MOBILE BROADBAND FOR PUBLIC SAFETY The Australian emergency services sector is pushing the federal government to set aside spectrum for public safety mobile broadband.

hen it comes to spectrum allocation for mobile broadband, which entities should take priority - commercial carriers (who pay big bucks to government for spectrum rights) or agencies that provide essential public services (who can’t, and many would say shouldn’t, match what the carriers pay)? How can the needs of both user groups be met? At the recent ACMA Radcomms 2013 conference in Sydney, Mark Burgess, CEO of the Police Federation of Australia, forcefully argued the case for public safety agencies to be allocated a fair share of spectrum for mobile broadband public safety communications - such as the unsold portion of 700 MHz digital dividend spectrum. The following is an edited version of Burgess’s presentation. In 2011, when giving evidence to a US Senate Committee on broadband spectrum for public safety, New York Police Commissioner Ray Kelly told the committee that a 16-year-old with a smartphone has a more advanced communications capability than a police officer carrying a two-way radio. In Australia there are around 400,000 first responders across our public safety agencies. Our roles are unique. When society and nature are at their worst, police and emergency services need to be at their best. We believe our governments have an obligation to emergency services personnel to provide them with the best equipment and resources that will enable them to do their job effectively and efficiently, and to protect the public and each other. A mobile broadband capability fits into that category. Deloitte Access Economics, in a June 2013 report, ‘Building our Nation’s Resilience to Natural Disasters’, said: “… mobile broadband would achieve a more timely assessment of incidents, more effective command, control and coordination of activities, faster and more appropriate response to incidents that will lead to a more productive use of resources and improved personal safety”.
The legislation When the Keating government embarked on radical market-based reform of spectrum allocation in 1992, it foresaw that a problem would arise, namely how to ensure
www.CriticalComms.com.au
that non-commercial users like police and emergency services had affordable access to spectrum into the future. Recognising that these not-for-profit public safety agencies could not compete in an open market system against the big telecommunications companies for a rare commodity, the government built a series of safeguards into the Radiocommunications Act 1992. The Act specifies that the system must make adequate provision of spectrum for law enforcement and emergency services. Parliament was saying that spectrum has a public safety value, not just a value for commercial uses. Charging for spectrum must also take into account the value of non-commercial use of spectrum. In other words, the public safety agencies should not be expected to pay the commercial rate for their spectrum - the Act provided for spectrum to be reserved for these essential public purposes so that they would not have to compete at auction. These safeguards need to be upheld today more than ever, as the big telcos vie for spectrum at the expense of public safety and the public interest. It is the responsibility of the government and ACMA, under the Act, to ensure that the spectrum needs of law enforcement and emergency services are directly met and not to send these public safety agencies to do the best deal they can with one or more of the major telecommunications companies at commercial rates.
Factors in valuing the spectrum The Deloitte Access Economics report indicated that the total economic cost of natural disasters in Australia averages $6.3 billion per year, and that this is expected to double by 2030, and to reach approximately $25 billion by 2050. Of the costs of disasters to governments, 80% falls to the federal government. Currently Australia spends $1 on pre-disaster measures and $10 on post-disaster recovery. Motorola Solutions told the 2013 Parliamentary committee on spectrum for public safety, that “every dollar spent on public safety returns $5 to the community”. Deloitte Access Economics also says a simple cost-benefit analysis shows how government funds would be saved by bringing forward investments in predisaster resilience measures. It would come as no surprise that we consider

PUBLIC SAFETY Wikimedia/Mriya needs to be mission critical hardened. • The carriers do not need to have the security considerations that public safety requires. A further consideration is ownership - what if the carrier were owned by a foreign government? What would be the implications for the security of the network? spectrum for public safety to be such a resilience measure. Our view is that ACMA should take a whole-of-government approach when making spectrum decisions. This means taking into account these real costs to the federal government.
Public safety mobile broadband There is currently an argument about the need for a dedicated public safety mobile broadband network. We suggest that this argument has been had and resolved. Two recent parliamentary enquiries have come to a unanimous and bipartisan view that a dedicated public safety mobile broadband network is the way forward. In 2011 a Senate Committee inquired into the capacity of communications networks and emergency warning systems to deal with emergencies and natural disasters. The committee recommended the Commonwealth Government allocate sufficient spectrum for dedicated broadband public protection and disaster relief (PPDR) radio communications in Australia. In 2013 the Parliamentary Joint Committee on Law Enforcement conducted an Inquiry into Spectrum for Public Safety Mobile Broadband. That Committee had as its chair the former Attorney-General, Robert McClelland, who had also previously been Minister for Emergency Management. The deputy chair was Senator Fiona Nash, Deputy Leader of the National in the Senate and now Assistant Minister for Health. Other members were Senator Stephen Parry, Deputy President of the Senate and Michael Keenan, then Shadow Minister for Justice and now Minister for
10 Critical Comms - Nov/Dec 2013
Justice who now also has responsibility for Emergency Management. It was not a lightweight committee. The committee made five key recommendations, including that a minimum of 20 MHz should be allocated to public safety in either the 700 or 800 MHz band. What brought them to that conclusion? When the committee did the analysis between a potential carrier model for public safety and a dedicated public safety network, there was only one conclusion they could come to. Consider the following points: • A public safety network has to be able to deal with a variety of incidents, from day-to-day operations, right through to those mission-critical events such as natural disasters, major incidents and even terrorist strikes. • The carriers’ model is built on revenue growth and profits for shareholders, whereas the public safety model is built on the premise of protecting life and property. • The carrier’s model is designed for normal day-to-day operations. Their networks can quickly be degraded with traffic overload, whereas public safety is built on my earlier premise - when society and nature are at their worst, public safety systems need to be at their best. • The carrier’s model is built on oneto-one communications; public safety is one to many. • The carrier’s model is based primarily on heavy downloads whereas public safety will rely on heavy uploads. • The carrier’s network is built to a commercial grade while public safety
A new government Did the federal election change anything? We think not. If anything we think it’s enhanced our prospect of getting a public safety network developed. In the lead-up to the 2013 federal election, we posed the following question to the major political parties: “The PFA seeks your party’s commitment to provide a minimum of 20 MHz of the 700 or 800 MHz band spectrum for a dedicated mobile broadband network for Australia’s public safety agencies so that inter-operable communications become a reality across the nation.” The Coalition gave a fairly detailed response, but the key point was: “If elected, a Coalition Government will conduct a rigorous cost-benefit analysis into the question of emergency services wireless communications and consider the most cost effective means of upgrading Australia’s law enforcement and emergency services mobile broadband network. The Coalition will continue to carefully investigate this issue and seek to weigh the various competing public interests in consultation with stakeholders and State and Territory Governments.” We welcome the Coalition Government’s commitment to conduct a rigorous costbenefit analysis. We think that will play significantly in favour of public safety agencies. The cost-benefit research conducted by Deloitte Access Economics and others will be interesting reading for the new minister. A May 2013 report by Professor John Ure from the University of Hong Kong, titled ‘A Study of Value and Opportunity Cost in the Assignment of Radio Spectrum’,

researched eight economies in the AsiaPacific region - Australia, China, Indonesia, Malaysia, New Zealand, Singapore, South Korea and Thailand. His policy findings are: • On a social cost-benefit basis the benefits of assigning broadband spectrum to dedicated PPDR services on an exclusive basis far outweigh the costs as measured by opportunity cost. • There is justification on a cost-benefit basis for allocating the spectrum that is considered sufficient for national needs. In all cases the cost-benefit analysis seems to support a case for up to 20 MHz and, in every case except Singapore, up to 30 MHz if necessary. • The decision would need to be based upon a realistic assessment in each country of what contribution broadband would make to reducing the risk of loss. • On a cost-benefit basis the opportunity cost is insufficient to justify marketbased assignments of spectrum for PPDR purposes. What this means is that on a costbenefit basis, it is better to allocate 20 to 30 MHz of spectrum for public safety
12 Critical Comms - Nov/Dec 2013
than to auction it to commercial carriers to achieve additional funds for the Federal Budget.
The Police Federation’s position As a result of our work, and that of many others, we’ve come to a number of conclusions. First, public safety needs mobile broadband communications. It is in the public interest. This must be a dedicated network controlled by public safety because our needs are so different from those of commercial networks. Secondly, there is a shared responsibility between the Commonwealth Government and state and territory governments for emergency management. The federal government has the spectrum; the states are prepared to invest in the development of the networks. And remember, the states are not starting with a blank piece of paper as many seem to suggest - they already have significant physical infrastructure that they would be enhancing. (Ericsson, in its submission to the 2013 Parliamentary
Inquiry, revealed that the construction of physical infrastructure by way of towers and sites - which many of the public safety agencies already have - represents 80% of overall network costs, compared to the 20% cost of equipment.) And the federal government will need access to the state networks for mission-critical incidents and major events like G20. Thirdly, there are serious doubts about the feasibility of public safety agencies roaming or overflowing onto public networks during critical incidents. While a report on this aspect is due on this shortly, many people have advised us that technically it’s possible but there would be serious flaws in such a system. Flaws that could jeopardise the safety of emergency services workers and the public. It is a risk, unless we can be guaranteed otherwise, that we think is too great to take. The possibility of commercial carriers or the NBN accessing the public safety network when it is not in high demand should be seriously considered as a way of ensuring efficient use of spectrum. The caveat is that the public safety agencies must have control of decisions about spectrum sharing. What we don’t have agreement on yet is the amount of spectrum public safety needs, although the Joint Committee concluded that a minimum of 20 MHz is necessary and it will come as no surprise that we agree. When a final decision is made and everyone has locked himself or herself into a position, I hope we’ll have got it right. When we have the next Royal Commission, Commission of Inquiry or even a Coronial Inquiry into a natural disaster or some other major critical incident - and we will - this issue and the decisions that were made will be under the microscope. If we’re judged to have got it wrong, whoever is in the witness box at the inquiry will be in the loneliest place in the world trying to justify their decisions. Mark Burgess will take part in ‘Workshop 3 - Mobile broadband & LTE for critical communications’ at the Comms Connect 2013 conference in Melbourne.

Hytera
SAFE CITIES ARE SMART CITIES Reliable, robust communications - personal, industrial and governmental - have become an essential part of our society’s fabric. Hytera’s Peter Clemons argues that this trend will only increase, and that that’s a good thing.
W
e live in an increasingly interconnected world, powered by an explosion in communications capabilities. What roles will communications continue to have in making our lives better, and can it make our cities safer and smarter? Peter Clemons is head of TETRA Business, Americas, for Hytera Mobilfunk, the German division of Hytera Communications, and a regular speaker at the Comms Connect conference, having delivered keynote presentations for the past three years on a wide range of topics, with particular focus on the future of TETRA and critical communications. Peter will return to Melbourne next month for Comms Connect 2013, to explain how cities must be safe before they can be truly smart, and how Hytera is working to make this vision a reality. Peter is renowned within the industry for taking a forwardlooking approach to business and business solutions. We caught
18 Critical Comms - Nov/Dec 2013
up with him during his busy schedule and asked him to give us a forecast for the future of critical communications. First up, Peter, how did you get involved in critical communications? It was such a long time ago that it is hard to remember now. I’d studied and worked as an academic and economist in Latin America for a number of years and then returned to Europe during the 1990s, where I got involved in telecommunications and managed to carve out a niche within the PMR sector, working for a number of TETRA manufacturers as well as helping out end users as a consultant. TETRA was, and continues to be, my main focus and I was honoured to become a director and board member of the TETRA Association - now TCCA - in 2010, serving a two-year term before returning to consulting and then joining forces with Hytera to develop the next generation of PMR solutions.
www.CriticalComms.com.au
SAFE AND SECURE HOWEVER, THE SAFER OUR SOCIETIES BECOME, THE EASIER WE TEND TO FORGET HOW IMPORTANT PUBLIC SAFETY IS.
Do you see critical communications continuing to grow? During the 1970s and 1980s, land mobile radio was synonymous with mobile communications, before the days of GSM. Nowadays, almost everyone has an internet-enabled mobile phone, smartphones are everywhere and we all depend on mobile applications during our daily life. More and more essential services are delivered remotely and via smart mobile devices. I think this trend is irreversible and requires a total rethink of how we manage mobile networks, putting critical communications at the core of modern societies. The PMR community has a long history of providing secure, reliable, alwaysavailable services, so we must make sure we have a role to play in this mobile revolution. There are many options for businesses and agencies looking to adopt a critical communications system. Is TETRA still a force to be reckoned with? I have no doubt that TETRA will remain at the core of advanced critical communications solutions for many years to come around the world. There has never been a standard quite like TETRA and there will probably never be another one like it in the future. In today’s complex, increasingly integrated world, no single technology can provide the full solution for professionals working in demanding environments but TETRA provides as much as 95% of the total solution today when TEDS (TETRA Enhanced Data Service) is included. Broadband solutions such as LTE can work alongside TETRA to provide higher-speed data and video solutions for the foreseeable future. On the subject of broadband, do you agree with those who say that LTE will be the complete solution that everyone has been waiting for? There is no doubt that LTE will be a success. It would be naive of me to suggest otherwise, considering the amount of resources being invested by major manufacturers, operators and developers within the global 3GPP framework. All major PMR manufacturers, including Hytera, are also looking at how we can use LTE to provide faster data rates for our customers in the future. However, LTE has not been designed from the beginning to cope with the demands of the critical communications community so we need to remain engaged with 3GPP and the commercial vendors and operators in order to create the consensus required to deliver critical broadband solutions in the medium term. As the concepts of ‘safe cities’ and ‘safe communities’ develop during this decade and the next, both the commercial and critical communications worlds will need to come together to guarantee high levels of security expected by citizens. This will take several years to achieve, so we will be kept busy and will have to remain vigilant for a long time to come. Tell us about Hytera and how it is tackling the critical communications future. Hytera is the fastest-growing PMR solutions provider in the world. This month we are celebrating 20 years in the industry and there will be a big birthday party in China. From the beginning, Hytera has focused on providing high-quality products and solutions at an affordable price for the most demanding users, changing industry business models in the process. As convergence continues and solutions become more sophisticated, Hytera has moved into the high-end systems business with DMR Tier 3 and TETRA/TEDS offerings that are taking those industry standards to new levels.
www.CriticalComms.com.au
TETRA in particular is a well-known, mature global standard that continues to evolve to form the base for current and future smart society solutions including smart cities, smart grid, etc. Hytera is at the forefront of these developments, so we are truly in exciting times. Hytera has been expanding via acquisition in recent years, hasn’t it? Can you tell us about the strategy there? At the beginning of 2012, Hytera Communications acquired Rohde & Schwarz Professional Mobile Radio GmbH, the well-respected German TETRA systems manufacturer, enabling Hytera to become a full TETRA solutions provider. The renamed Hytera Mobilfunk GmbH, based in Bad Munder, Germany, as Hytera’s main TETRA Centre for Competence, is now the focus of TETRA R&D activities within the group. And then last year the wireless protocol specialist company, fjord-e-design GmbH (FED) was acquired in order to accelerate TETRA/ TEDS development and prepare for the challenges of the future. Hytera has already delivered a TETRA Release 2 (TEDS) solution for Lima Police, Peru, based on the latest DIB-500 Release 5 base station which offers best-in-class TETRA solutions. Your address at the upcoming Comms Connect will cover ‘safe cities’ and ‘smart cities’ - how do you define those terms, and what is the relationship between them? Security is the basis for all societies. If authorities are unable to provide a secure environment for their citizens, it is unlikely that communities will thrive and flourish. This leads to a more uncertain economic environment where future investments cannot take place. Unsafe, precarious societies are forced into survival mode, living day by day, as we unfortunately witness in conflict zones around the world. An iPad is of limited interest if food and water are scarce or property rights cannot be guaranteed. However, the safer our societies become, the easier we tend to forget how important public safety is. Advanced critical communications solutions based on technologies such as TETRA continue working 24/7 in the background to make our cities safe, providing the conditions for the possibility of the emergence of smarter cities built on applications that enhance and enrich all our lives. With technology and societal evolution moving so quickly, is it becoming harder to anticipate the technologies and solutions that will be needed in the near and medium future? That’s a good question. What we know for certain is that the future will be different and we will have to continue to deal with unexpected events that will challenge our emergency services and force us to come up with better and better solutions. Those societies and companies that are best able to adapt to the new circumstances will thrive and prosper. Those societies and businesses that refuse or struggle to adapt will have to go through difficult times. It is up to Hytera and other like-minded technology companies to listen to users, identify and anticipate changing circumstances and work together with the rest of the critical communications community to continue delivering the best possible solutions at an affordable price. This is the best recipe for delivering safer and smarter cities and nations in an increasingly volatile world. Peter Clemons’ Comms Connect keynote address, ‘Safer cities will be smarter cities’, will be at 9.20 am on Friday 22 November. Hytera is a Platinum Sponsor of Comms Connect 2013.

Case study
Keeping a city energised
O
ne of the largest energy companies in Seoul, South Korea, urgently needed to replace its legacy communications control system with a 21st-century solution. To call Seoul, South Korea, a megacity would be an understatement - it’s the world’s second largest metropolitan area, with a population of 25.6 million people. More than half of the country’s residents live in Seoul. Those residents need a lot of energy, including natural gas. Samchully City Gas is a natural-gas distribution company that serves Seoul, supplying not only liquefied natural gas to residential and commercial customers, but also the gas that fuels the city’s steam supply and power-generation systems, fuel cells, cold- and warm-water supply systems, and even the city buses. With 5000 employees and an annual revenue of approximately US$2.33 billion, the scope and complexity of Samchully’s operations reflect the scale of the city it serves. That’s why Samchully relies on a centralised communication system to coordinate, control and manage its operations. Samchully recently installed Zetron’s DCS-5020 Digital Console System with the help of Seoul-based communications equipment provider Hanswell. The solution is providing Samchully with the updated technology and functionality it needs to manage its extensive operations. The need to update Prior to 2012, Samchully was using remote desktop equipment for its operational communications. The equipment had been in use for many years, however, and was beginning to fall behind in its ability to meet the company’s evolving needs. In addition, communications technology had advanced considerably over those years. Company officials began to realise that their operations could benefit greatly from the improved functionality and additional features an updated, more comprehensive communications solution would offer. This included capabilities that would allow them to combine multiple devices and resources into a single system and provide a graphical user interface to control them all.
www.CriticalComms.com.au
The situation became more pressing when the need arose to use multiple iDEN devices on the system; the existing equipment could support only one such device. Samchully began searching for a vendor to help it obtain, design and implement a new communications system based on current technology. After considering a number of proposals, they awarded the project to Hanswell. Based in Seoul, Hanswell provides two-way radio equipment and RoIP, dispatch and intercom systems to public- and privatesector clients throughout South Korea and Asia. Hanswell Vice President Sebastian Beck explains some of the most critical factors that contributed to the company being chosen for the project. “Not only have we had a long-standing, positive and successful business relationship with Samchully over the years,” says Beck, “but our proposal was based on Zetron’s DCS-5020 Digital Console System. The DCS-5020 would be able to provide the centralised, updated and improved functionality Samchully was looking for and would more than fulfil their requirements of the project.”
Zetron was chosen for other reasons as well. For the past seven years, Zetron’s Australasia office in Brisbane and its North Asianbased territory manager have worked together to support Hanswell’s business-development efforts throughout South Korea. Zetron has also responded to local market requirements by engineering its key dispatch products so they can easily be localised into the language of local users - in this case, Korean. This combination of easy localisation and local support has been a key ingredient of Zetron’s success throughout the non-English-speaking countries of Asia. And it contributed significantly to the decision to use Zetron equipment for the Samchully project. >

Smooth operators The solution for Samchully comprised three positions of Zetron’s DCS-5020, 10 iDEN ports, three PBX lines and 12 hotlines. The equipment was installed in Samchully’s command centre in a process that Beck says was completed smoothly and easily. Once the new solution had been installed and thoroughly tested, Hanswell trained Samchully’s 12 operators on the best and most effective ways to use it for their purposes. The training and transition to the new system went more quickly than anyone had expected, thanks in part to the system’s intuitive operation. “Because the DCS-5020 is so easy to learn and use,” says Beck, “the operators caught onto it readily. In fact, many of them found that, once they got used to the system, they were able to appreciate more and more the extent to which it simplified their tasks and helped them function more efficiently. That’s in large part due to the
fact that the DCS-5020 allows them to control everything from the console. They’re able to attend to their commandand-control tasks and operations without having to focus on the equipment itself.” Beck says that the customer is extremely pleased with its new equipment. “They particularly like the system’s highquality audio and flexible, easy-to-use graphical user interface,” he says. “They also like its intuitive operation, web and closed-circuit TV integration, and its ability to integrate and connect radios and other communication lines and resources, such as PSTN phone lines, to their radios. Its support for Korean is also a real plus.” Although the installation at Samchully’s command centre has been completed, this is not the end of the story for Hanswell. “Thanks to the success of this project, and because the features of the DCS-5020 meet the requirements of the Korean National Emergency Management Agency [NEMA],” says Beck, “we are currently in the process of reviewing second and third projects that will also involve the DCS-5020.” Zetron Australasia Contact info and more items like this at wf.net.au/V455

Fluke Calibration has introduced the 5730A Multifunction Calibrator, designed for calibration professionals who require the most accurate dc/low-frequency signals available in a multifunction calibrator. The device builds on the 5700A/5720A with improved accuracy, new digital components and a large full-colour, touch-screen display. The display brings all of the calibratorâ&#x20AC;&#x2122;s status and settings into one location, making any operation accessible with the touch of a finger. For laboratories running their existing 57XX calibrator under remote control, the 5730A can be set to run in 5700A/5720A emulation mode, eliminating the need to rewrite system software or procedures.
Satellite RoIP In remote field work, VHF and UHF have always had inherent coverage limitations. But today, operators can have a radio IP network via satellite that solves many coverage problems. AST Australia has focused its efforts on providing satellite comms-on-the-move with radio IP connectivity. In collaboration with Cobham, a new mobile satellite L-band solution has been developed that provides a basic fist microphone PTT solution that can operate either in a moving vehicle/vessel or at a fixed location using both GSM and satellite connectivity. The Cobham Explorer PTT is a purpose-built L-band satellite RoIP solution designed to be bandwidth efficient on the Inmarsat network to provide a global solution. Additionally, there is the advantage of using GSM when available (there are ports for two GSM dongles), which is said to provide a true least-cost route between mobile and satellite. Also provided is a 4-wire ear and mouth solution, with which operators can add existing radio infrastructure and connect various nodes to essentially become a bridge, a repeater or a simple

Quadband antenna The G Spotter Omni Quadband ‘Hard Hat’ antenna has been designed with emergency services vehicles in mind, with a single low-profile antenna providing four different outputs in a single unit. The antenna has two 850-900 Mhz cables enabling current 3G and the soon-to-be-activated Telstra LTE MiMo reception, as well as a single 2.4 GHz Wi-Fi cable and a separate UHF cable (that can be customised to any suitable frequency). The randome is made from a tough fibreglass that is very robust. The design can be fitted to larger emergency vehicles, in particular rural fire tankers, where traditional whip antennas have a high rate of damage. Field testing has shown that there is no interference or loss of performance when transmitting a UHF signal and concurrently utilising 3G wireless broadband and at the same time creating a Wi-Fi hotspot inside the vehicle. The antenna also creates a large area Wi-Fi hotspot outside, enabling meshing of Wi-Fi across vehicles as well as data bonding for greater bandwidth throughput and GPS tracking as future possibilities.

MILITARY CONNECTIONS Peter McNeil, Product Marketing Manager, L-com Global Connectivity
Intended to bring harmony to military design and procurement, military standard or MIL-STD devices are widely used in the commercial and industrial communication fields.
B
uilt for the toughest of conditions, military-grade components are often also used for civilian purposes, such as mission-critical communications for emergency services, mining operations, transport and logistics, to name just a few. Such utilisation can guarantee the best possible performance under the most trying of conditions, such as extreme heat or cold. Outlined here are some different types of purpose-built connectivity products that are designed for harsh military applications. Communications systems for use in combat operations have special requirements compared with non-military, commercial systems but are nevertheless suitable for stringent commercial usage. Many of the voice, video and data systems used by the military are mobile and designed for rapid deployment in harsh environments where temperature extremes, shock, vibration, dust and moisture can be prevalent. The constant jostling, vibration and even major shock experienced in combat operations could potentially disable a system based on commercial standards. Other potential hazards include heavy EMI and RFI cause by proximity to noise-generating devices such as motors, switching power supplies and microprocessors. When designing a communications network for such conditions, engineers can make use of specialised products to address these factors and more.
Fibre optics The use of fibre optics provides several benefits. First, it is immune to EMI and RFI. Secondly, it can support very long distances before a repeater becomes necessary. Thirdly, fibre offers very large bandwidth
36 Critical Comms - Nov/Dec 2013
and can be used in video, voice and data applications. And lastly, the cost of fibre continues to decrease. Many fibre products are now available to address the needs of military-style applications. Specialised military connectors such as Straight Tip (ST) are offered with extra-heavy tension springs to assure physical mating will not be compromised in the event of a major shock or vibration. Variations are available that feature a locking mechanism that prevents optical disconnects in high-shock or -vibration conditions. Other militarised fibre-optic connectors include ingress protection that feature extra-robust strain reliefs and screw-lock mating for solid optical connections, even when subjected to shock and vibration. Typical strain relief on these connectors is well over 250 newtons, which is more than 50% better than standard, commercial designs. This added protection ensures the cable assembly will survive incidental contact during field use. Fibre cable is now also offered in military/industrial styles featuring armour (typically corrugated steel), as well as special crush- and impact-resistant simplex and duplex fibre patch designs.
Copper Ethernet cabling Cat 5e/6 Sometimes fibre-optic systems cannot be used due to the presence of legacy equipment, or for various design reasons. In traditional civilian/commercial installations, unshielded twisted pair (UTP) systems are fine for controlled environments where cabling is often installed and then not touched for years. But for military-style applications, UTP will not cut it. But by coupling shielded twisted pair

Military standards Standards for military-grade connectors grew out of efforts by the US Department of Defense in the 1930s to standardise devices for, particularly, aeronautical applications. Originally specified with AN (Army-Navy) numbers, they are today known by their Military Standard, or MIL-STD, numbers, sometimes informally called MIL-SPEC. And although originally developed for military purposes, they are now widely used for industrial, commercial and aerospace applications. Military specifications exist for electrical connectors and for fibre-optic connectors. The primary ones of concern are MILDTL 26482, MIL-DTL-38999 and MIL-DTL-5015. MIL-DTL 26482 defines the requirements for “two series of environment resisting, quick disconnect, miniature, circular electrical connectors (and accessories)”. The standard describes requirements for operating temperatures and pressures. MIL-DTL-38999 describes four series of “miniature, high density, bayonet, threaded, or breech coupling, circular, environment resistant, electrical connectors using removable crimp or fixed hermetic solder contacts, and are capable of operation within a temperature range of -65 to +200 degrees Celsius”. These kinds of connectors are suitable for SWAMP (severe wind and moisture problem) conditions. The widely used MIL-DTL-5015 standard defines circular electrical connectors with removable crimp or solder contacts, with several temperature rating standards up to +200°C. There are many other standards, such as MIL-DTL-83513, which defines a micro connector (Micro-D connector) for use where space or weight considerations are a priority. Others include MIL-C-83522 and MIL-DTL-83526, both of which are concerned with fibre-optic connections.
MIL-DTL-5015 connector.
Military standard 38999 connectors.
(STP) cabling and ruggedised military-style connectors, most design requirements can be met. Many styles of military-grade connectors exist today, including: transversely sealed jack and plug options in zinc-nickel, which provides excellent levels of corrosion protection; or anodised finish, which also increases corrosion resistance and wear resistance. These types of connectors feature a compression nut that establishes the cable strain relief, thus keeping the connection even when bumped or hit. Additionally, these connectors support 360° shielding when terminated to the cable’s shielding.
Jacket compounds Another consideration is the type of cable jacket compound. Typical UTP cabling utilises PVC in the outer jacket. PVC is very toxic when burned and can act as a wick, increasing the spread of fire. A popular jacket type used in military systems is low smoke zero halogen (LSZH), which produces very little smoke and no harmful

halogens such as fluorine, chlorine and bromine, which can damage expensive communications equipment and endanger lives. LSZH cables will self-extinguish and are used extensively in shipboard, aerospace and mobile vehicle applications where confined space communications and networking is common. Another type, polyurethane, stands up well to damaging UV rays, is resistant to oils and petroleum-based products, and is very resistant to mechanical abuse in situations where abrasions and cuts are commonplace. One downfall, though, is that they give off very toxic gases when burned and do not self-extinguish. In summary, connectors and cables originally designed for use by the military are also widely used in general industry and often are used more for commercial projects than military projects. Public safety is one such area, where devices are required to be of a very high standard and especially to be water resistant and rugged.

Signal and spectrum analyser The R&S FSW67 high-end signal and spectrum analyser covers the frequency range from 2 Hz to 67 GHz in a single sweep, simplifying test set-ups. It does away with external harmonic mixers and therefore does not require complex cabling. Image frequencies and other spurious emissions caused by harmonic mixing are suppressed. With its analysis bandwidth of up to 320 MHz, the FSW67 also measures wideband, hopping and chirp signals. As users can perform spectrum measurements and modulation measurements in the 60 GHz band, the FSW67 is not suitable for the development, testing, verification and production of transmitters and components for radar applications, satellite and military communications systems. The analyser also provides valuable assistance when performing development tasks relating to fast wireless communications based, for example, on WiGig (IEEE 802.11ad) or WirelessHD. The integrated multistandard radio analyser (MSRA) measures spectrum and modulation parameters of signals with different modulations simultaneously and also correlates these signals in time. With the MSRA function, users can efficiently analyse how and why different signals affect each other. The 12.1â&#x20AC;ł (31 cm) touch-screen interface makes operation very convenient, especially for complex measurement tasks. The MultiView function allows users to simultaneously display multiple measurements and applications. Rohde & Schwarz (Australia) Pty Ltd Contact info and more items like this at wf.net.au/V403

The TX6500S radios are a robust communications solution when managing team communications in a business environment but are equally suitable for camping, touring and 4-wheel driving. A comprehensive range of aftermarket accessories provides multiple charging options, hands-free communication choices and radio protection. Digital signal processing measures, filters and compresses standard analog radio signals and converts them to a digital format, eliminating much of the conventional processing and time-consuming manual alignment. Advanced signal management (ASM) identifies interference caused by strong local signals on adjacent channels and prevents these from opening the squelch control. ASM also minimises distortion of reception by finetuning the receiver frequency to match that of the incoming signal. Dynamic volume control automatically compensates for variations in received audio level and, when activated, provides a constant audio output level, enhancing quality of reception and the simplicity of use. Other features include: five extra programmable receive channels with alpha labelling; SelCall; CTCSS; DCS; and voice inversion scrambler. GME Contact info and more items like this at wf.net.au/V489

GUNS, MINES AND LTE LTE is quietly gaining a foothold in non-traditional areas. To learn why, Jonathan Nally spoke with Simon Lardner from Challenge Networks and found out why his teams sometimes have to be accompanied by armed guards packing Uzis.
W
hich technology is best for your critical communications circumstances? Is it TETRA, P25, dPMR, DMR, LTE? In many cases the choice might be obvious, but in others not so. According to some, LTE - traditionally a consumer-orientated technology - could be the elephant in the room. Challenge Networks has installed 2G, 3G and LTE mobile phone networks across the Pacific and is now moving into the mining sector in Australia. Lardner will present a case study on LTE for major resources projects at the Comms Connect conference in Melbourne in November. He’ll also take part in one of the workshops (mobile broadband and LTE for critical communications) the day before the conference begins. What sort of work does Challenge Networks do? Historically, we’ve built mobile phone networks for typically small countries, such as islands in the Pacific - Fiji, Vanuatu and so on. We are probably one of only two companies in the world that does that; it’s fairly specialised. We’re now moving more into the mining segment, which kind of makes sense - mines are like very small countries, like an island I guess. They’re typically in the middle of nowhere, often with reasonably difficult climatic conditions. So we’ve gone from being in traditional carrier networks and now moving into the mining segment. And my presentation will be on some of the challenges you have in building small networks. So what are some of those challenges? It’s mainly about money. Anyone can develop anything - it’s making it cost-effective that is the key thing. But the mining segment does have some specific needs. Most mobile networks, in the LTE type of
48 Critical Comms - Nov/Dec 2013
space, at the end of the day are still designed for consumers. They’re not exactly designed for true industrial applications. The trick is to get what is historically a consumer network to work in an industrial sense, and that’s mainly about reliability and ruggedness. So you only handle LTE? You don’t get into TETRA or other systems? No, we’re very specifically in the LTE space. We’re not an IT company and we’re not a comms company in the TETRA, P25 sense. We’re essentially a telecoms company that is jumping market segments a little bit. Do you work through subcontractors or do you get your hands dirty on the ground? We pretty well do it all, and that’s partially due to the legacy of where we’ve come from. We tend to work in island nations, so we fly in a bunch of guys who basically do everything, although we tend not to do pure civil works, because that’s something that can usually be done more economically by someone locally. Similarly in a mine site, typically there’s someone already in the mine who does civil works, and they’re the people you want to work with. Which island nations have you worked with? Most of the Pacific including Kiribati, Vanuatu, PNG, Fiji, Samoa and Tonga. We have also done some work in Asia and Africa. I just got back from Kiribati, where we’re installing a 3G/LTE network. They’re very challenging places logistically, because if you don’t get what you need on the boat this month, you have to wait for perhaps another eight weeks for the next boat. But for sites in Australia, typically there is a daily road train delivery going to the mine. So while it is a bit tricky getting stuff to these Australian locations, it’s nothing compared to getting a base station into Kiribati.

What is your impression of the future of LTE? There are a couple of aspects to it. One is that many people have a lot of investment in a number of technologies, and there’s a huge legacy in those. I think LTE is just another inclusion into the portfolio of things you can use. Emergency communication at one end of the continuum starts at hand signal flares. It then moves on through systems such as TETRA and P25, and LTE is just another one. I don’t think LTE is the salvation of the world, its just another technology that can work in some applications. I think one of the valid criticisms of LTE in the emergency comms sector is that it is designed for consumers. And that’s what I’ll be talking about at the conference - it all depends on how you build the network. So you can build an LTE network that’s more ruggedised for stringent applications? That’s right. Because of our experience building consumer networks, we’ve learned what works and what doesn’t. But a consumer network is still a consumer network - if you’re building an industrial LTE network, that is a completely different animal. One of my key points is that the mistake that some people make is saying that consumer and industrial networks are the same thing, and they’re not. There are a number of things you can use LTE for. One of them is as a replacement for where people have been using Wi-Fi. So one place where LTE is more likely to be used is the mining segment, in physically large mines, because the big thing that LTE has up its sleeve is that a base station can cover up to 30 or 40 kilometres, whereas Wi-Fi can cover 100-200 metres. So when you start to look at telemetry and things like that, which have traditionally been done on Wi-Fi, LTE is a whole new game and it can be a lot cheaper than Wi-Fi.

LTE FOR MINING
And I imagine that LTE would give you lots of other benefits, such as being able to use normal mobile phones on the network as well? Coming out of the consumer space, you get a whole bunch of things for free, as it were. And one of those is that there is a variety of CPEs. So you have things from a $5000 industrial modem installed in a $10 million truck to do telemetry, to down at the other end where you have a $29.95 dongle that people use to surf the web at night. And all of them work on the same network. And so that’s where I guess LTE has its place. It enables you to be involved in a portfolio of services. It’s not a single game, so you can use LTE for things like talking to each other - standard voice comms. And then moving through the continuum you have data services - so being able to know where every truck in the mine is. Then you have consumer applications, where people can use their PCs around the mine and in dongas at night. And these things become more important as the mine becomes larger. For example, a large mine may be 35 by 35 kilometres in size with a car speed limit of about 25 kilometres per hour. So to get from where you stay at night to where you work can take you an hour. So if you have a meeting down at the other end of the mine, this can lead to significant time lost to travel. If you enable something simple such as mobile videoconferencing between people at opposite ends of the mine, there can be significant lost labour savings. And that’s an advantage of LTE over, say, P25 - the ability to broadband? The disadvantage of P25 and TETRA networks is that they have relatively low bandwidth. They’re mainly designed as voice networks basically. The handsets are also often quite expensive and have relatively limited voice capabilities - certainly compared to modern 3G or LTE networks. The advantages of P25 and TETRA are that they’re fairly reliable, and you can do things like group calling. LTE networks can now do all those things as well, especially if you build them specifically as industrial networks, which is what we do. So we can do group calls for anyone and everyone in the mine. But you would never do it in a consumer network, because it could kill the network if you were not careful. So if you build an LTE network for a mine, you need to build it so it is essentially bulletproof. Has your experience working in difficult island environments helped you to get the mining companies on board? From our experience in working in countries like PNG, we had an unofficial company motto: If you’re not being shot at, it’s a good day. And in some places in PNG there can be real safety concerns. So when we first went to the mines, they said, “You cannot do mines, you don’t understand how rough it is.” We then explained how in PNG we worked with people who had Uzi machine guns for protection - so we were used to working in challenging circumstances. So unless the mines start firing at us with semiautomatic weapons - which is what has happened to us in some markets - we’re pretty happy. Or unexploded ordnance, such as we found in the Solomon Islands. You’d dig a hole in the ground to build a base station tower and find mortars from World War II. So while the mining segment is tough, it’s not that bad! Challenge Networks www.challengenetworks.com.au

Industry Talking The end of 2013 will be dominated by the Comms Connect 2013 show in Melbourne and we are very pleased to be part of this event. ARCIA has been working with the event organisers to add more value and I believe 2013 will be the best event yet. Of course the gala dinner is a highlight and will again showcase the depth of the industry, with many different aspects represented from all over Australia. It will be tremendous to see so many people - from individual business owners, public safety organisations, consultancy groups, end-user companies and global suppliers - all under one roof. The industry awards presented during the gala dinner will celebrate the efforts of many professionals and are a great way to recognise those who are at the forefront of service delivery, engineering or in some cases have dedicated a large part of their working life to the communications field. I would encourage all members to nominate our silent achievers through the ARCIA website. Being on the ARCIA committee, you come to realise the amount of work that goes on behind the scenes to bring all this together. We should all be very grateful to the many people that are passionate about the Australian radio communications industry. The ARCIA committee has also started work on a number of items for 2014 in a number of areas that we believe are very important to our members. Industry training remains a focus and we are looking at new ways to engage with the ARCIA membership. There will be a session on training needs at Comms Connect and I encourage all members to participate and make their views known. Our industry also faces a number of key spectrum challenges with the implementation of the 400 MHz plan, the impact of the 900 MHz on many areas of business, as well as the decision by ACMA to increase high-density UHF apparatus licences by 15% per annum. It is very important that ARCIA continue to advocate on the industryâ&#x20AC;&#x2122;s behalf to all levels of government. When you consider what radio or SCADA systems are used for and the repercussions were they to stop working, it is clear that our industry is under-represented in the thinking of governments. New developments such as LTE for public safety also need to be considered by all stakeholders. Our industry has a role to play to ensure that critical public safety needs are met and that the crucial importance of existing technology options are not lost. Our industry is seeing a convergence of technologies and we must all adapt to best serve our clients. Finally, the ARCIA website continues to be updated and improved with new content being added all the time. Make sure you use this valuable source of information regularly and give feedback to ensure it becomes even more valuable.
Emergency call software Rohde & Schwarz has reached a milestone in the introduction of voice over LTE telephony for the IP multimedia subsystem (IMS). The company has verified test cases for IMS emergency calls over EPS/EUTRA in compliance with GCF Work Item 154. All mobile phones and smartphones must be able to place emergency calls, both in their home network and in other networks - even without a SIM card. The correct signalling of an emergency call is crucial in an emergency. In cooperation with leading chipset makers, Rohde & Schwarz has verified test cases defined in GCF Work Item 154 for IMS Emergency Call over EPS/EUTRA. The R&S CMW500 multi-RAT protocol tester was used to test the RRC connection set-up for an emergency call and the IMS emergency call registration. Rohde & Schwarz says this is a key step in the transition toward pure LTE networks. In the past, placing emergency voice calls on LTE networks was especially challenging for network operators, chipset makers and consumer electronics manufacturers. The R&S CMW-KC504 IMS emergency call over EPS/EUTRA software option is available for the R&S CMW500 multi-RAT protocol tester.

Mobile surveillance system The Mobile Surveillance System (MSS) is a scalable system comprising mobile, solarpowered camera sites with radio and telemetry links to trailer-mounted bases. Typical applications are for security of mine sites and ad hoc deployment for crowd control. Currently deployed over an area of operations exceeding 70 km square and in some cases with links exceeding 100 km, the MSS is protected and capable of deployment in extreme weather conditions of wind, sea mist, temperature and with an associated highly corrosive atmosphere, which would attack and corrode deployed devices if poorly conceived. The radio links are based on DVT-B digital TV standards for high-quality video transmission and utilise COFDM digital technology to allow the cameras to be repositioned at will without suffering signal degradation common in both opencast and underground operations. The use of digital transmission opens up new opportunities for the operator to use the radio backbone to transmit GPS location data for vehicles within the area back to the control room. There is also the ability to mount cameras on vehicles and transmit this video back to the control room also.

802.11: SPEED VERSUS WIDTH ON 80 MHZ CHANNELS
Jonathan Ordman, Wavelink
When deploying an 802.11ac system, should you go for speed or RF channel width? This article provides the business case for why 802.11ac needs to be deployed on 80 MHz channels rather than 40 MHz.
W
hen planning an 802.11ac deployment you may hear recommendations to use a 40 MHz channel. While increasing the channel bandwidth is one of the primary ways of increasing data rates, the question remains as to whether it makes financial or technical sense to deploy 802.11ac if you are restricted to the same channel size as legacy 802.11n equipment. The primary reasons for deploying 802.11ac using a 40 MHz channel include spectrum availability, the need for Dynamic Frequency Selection (DFS) and destructive interference. Wider channels mean you need more spectrum. Traditionally, in an enterprise setting where multiple access points (APs) are deployed, you would deploy them on different channels. If you use a 1-in-3 frequency re-use plan you would need at least 240 MHz of spectrum or 3 x 80 MHz. DFS is a feature that lets the Wi-Fi network detect the presence of interference and dynamically move to a clearer channel. Deployment of a 1-in-3 frequency re-use plan with 80 MHz channels requires APs and clients to support DFS. From a client perspective, this means the client must be capable of responding to an 802.11 management action frame request to move to another channel. When deploying a traditional 1-in-3 frequency re-use scheme, you also have to worry about co-channel and adjacent channel interference. Interference deteriorates the performance of the network. To maximise throughput, it is important to avoid contention on the same
www.CriticalComms.com.au
channel and interference with adjacent channels. The spectral mask for 802.11ac 20 MHz and 40 MHz channels is the same as for 802.11n. The mask for an 80 MHz channel is an extension of the 40 MHz mask. A 40 MHz channel causes more adjacent channel interference (ACI) than a 20 MHz channel, while an 80 MHz channel is expected to cause more than a 40 MHz channel. In 802.11n deployments it is common to configure adjacent APs on non-adjacent channels, which means adjacent APs operate on channels that are at least 40 MHz apart. The power from transmissions in adjacent channels can spill into neighbouring channels and cause ACI. When deploying 80 MHz channels it isnâ&#x20AC;&#x2122;t possible to deploy adjacent APs on non-adjacent channels because there arenâ&#x20AC;&#x2122;t enough available today. It is therefore reasonable to conclude that if you are deploying in an enterprise environment using a 1-in-3 frequency re-use scheme with 80 MHz channels they will suffer ACI and performance will be impacted. The more traffic on the adjacent channels the greater the ACI and the greater the impact on performance. This has led to some suggestions that deploying 802.11ac on 80 MHz channels could result in worse performance than deploying 802.11n on 40 MHz channels.
Performance in a 40 MHz channel Technologies can be compared by looking at the maximum theoretical data rates. There are two technologies in 802.11ac Wave-1 products that are not in 802.11n. These are explicit beamforming and 256-QAM.

SMART SPECTRUM TO M A X I M I S E T H RO U G H P U T, I T I S IMPORTANT TO AVOID CONTENTION ON THE SAME CHANNEL AND INTERFERENCE
Although technically explicit beamforming was defined in 802.11n, it was not implemented because the specification provided the flexibility to implement beamforming in multiple ways and vendors did not support multiple mechanisms due to the implications for product costs. The 802.11ac specifications address this by defining a single beamforming mechanism. Explicit beamforming requires the beamformee or the client to provide explicit feedback regarding the channel conditions to the beamformer or the AP. The beamformer then uses this information to generate beams toward the beamformee. The advantage of beamforming is that it increases the range at which the higher data rates can be attained. The advantage of explicit beamforming defined in 802.11ac over the implicit transmit beamforming implemented in many of today’s 802.11n products is twofold. First, because it is based on channel conditions, the beamforming should be more accurate and result in a stronger received signal. Second, because vendors are aligned on a common mechanism it can be used for transmitted and received signals. The introduction of 256-QAM means that in extremely good RF conditions a signal can be modulated to carry eight rather than six bits per modulation symbol. This results in an increase in the data rate of 1.33x (8/6). This higher data rate can only be achieved in the best RF conditions. However, coupling 256-QAM with beamforming extends the range at which the higher data rate can be attained.
WITH ADJACENT CHANNELS.
The business case If you deploy 802.11ac in a 40 MHz channel, explicit beamforming has a very high probability of increasing the range at which you can get higher data rates. In addition to the transmit beamforming capabilities of 802.11n you should also have the benefit of beamforming on the uplink. Explicit beamforming does introduce higher overhead, due to the need to report channel conditions to the beamformer, but overall you can expect a performance improvement. It is impossible to say exactly what the throughput benefit will be as it varies with RF conditions and traffic loading but is it enough to replace the existing 802.11n deployment? The answer is clearly no. If you are currently in an 802.11g network is it enough to make you upgrade to 802.11ac over 802.11n? The answer to that depends on the equipment costs. The cost of 802.11n equipment is starting to drop significantly, while 802.11ac equipment carries the ‘new technology’ price tag. The bottom line is if you are considering deploying 802.11ac in 40 MHz channels there will be difficulty justifying it. To get the true gain out of 802.11ac you need to deploy it in 80 MHz channels.

Signal generator The Rohde & Schwarz SMW200A generates RF and envelope signals in real time in a single instrument, to enable testing of envelope tracking performance of power amplifiers. The high-end vector signal generator has been enhanced by adding the R&S SMW-K540 option for envelope tracking. This option enables quick and easy testing of envelope tracking power amplifiers for smartphones, base stations and tactical radios. The device meets the test requirements of chipset manufacturers by offering a solution that generates fully synchronous RF and envelope waveforms in a single instrument. Users can delay the RF waveform and the envelope waveform relative to each other by ±500 ns with 1 ps resolution. Due to its performance characteristics, the device delivers an extremely low-noise envelope signal at the analog baseband outputs. The signal generator calculates the envelope waveform from the baseband signals in real time, so that all communications standards supported by the signal generator as well as custom waveforms can be used. A large selection of flexible shaping functions allows users to optimise the envelope in real time. The envelope tracking parameters can be configured on the generator’s straightforward graphical user interface. Automatic envelope voltage adaptation is available to speed up set-up and testing time since the main parameters such as VCC voltage range, PAin range, DC modulator gain, DC offset and power offset only need to be entered once. Automatic recalculation of the envelope based on the power amplifier input level makes it possible to perform power sweeps over the amplifier’s entire input range.

Backhaul
Spectrum A key national resource
Welcome to Backhaul, where in each issue of Critical Comms we’ll take a trip down memory lane and look at the state of the industry 25 and 10 years ago. 25 years. Twenty-five ye a rs a g o , C r i t i c a l Comms began life as What’s New in Radio Communications, with the first issue published in Aug/Sep 1988. Rohde & Schwarz s i g n a l g e n e ra t o rs featured on the cover and stories inside included: a profile of UHF communications at the Mt Hammersley mine in Western Australia; the emerging field of packet radio; the introduction of five-tone sequential signalling for the Wyong Shire Bush Fire Brigade in NSW; and making the case for radio in the fight against satellite and fibreoptic comms. Looking over the new product announcements in that issue, cellular telephones were beginning to make an impact, CB radio was popular (this was the ’80s, remember!) and RFID (or RF Auto ID as it was then known) was on the cusp of explosive growth. 10 years. Exactly 10 years ago, What’s New in Radio Communications changed its name and became Radio Comms Asia-Pacific with the Nov/Dec 2003 issue. Tait was on the cover with new base stations and handhelds. This issue seems to have had a bit of a focus on HF, with a case study on HF radio telephones (Radtel) and a story on the use of HF by NGOs and peacekeepers in hotspots around the world. There was also an article on the Mid Murray Council in South Australia, which had decided to install its own radio and microwave network. It’s amazing to see how things had changed between 1988 and 2003 - we were now dealing with email, the World Wide Web, Windows systems, IP, VoIP, Bluetooth and Wi-Fi, and digital communications in general. Spectrum analysers had shrunk to become handhelds, wireless hands-free kits were all the rage and PCs had become mobile devices.

I am delighted to contribute to the inaugural issue of Critical Comms and welcome the opportunity to highlight some of the important spectrum work being delivered by my agency, the Australian Communications and Media Authority (the ACMA). I appreciate that I am speaking to a converted audience but it cannot be overstated just how crucial a resource spectrum is. It is one of the great enablers of the 21st century, a century increasingly being driven by technological innovation. Spectrum does not just facilitate communication; it has changed the very concept of how we interact with the world around us. This transformative capacity is not something that any of us, least of all regulators, can take for granted. Management of this finite national resource materially contributes to our region’s fundamental economic growth and social development. The past year has seen the ACMA deliver on a significant number of key spectrum initiatives, including the reallocation of the digital dividend spectrum; establishing new arrangements for a number of key bands; and implementing ongoing arrangements for the introduction of a new technologies and innovations. These achievements were the result of extensive work undertaken by the ACMA in close consultation with industry and government. I am proud of the high-quality outcomes that have been produced. However, there is no time to stop and rest. The ACMA’s spotlight has now shifted from the reallocation of the digital dividend to identifying mechanisms to meet the ever-increasing demand for spectrum to enable participation in the digital economy. Developments in technology have transformed the way we conduct most parts of our lives. Use of spectrum is no longer intermittent and discrete. Our devices - whether personal (like smartphones and pacemakers), private (like smart meters and asset trackers) or public (like disaster warning systems) - are now always on. There are a number of key implications of this seemingly relentless growth in demand for spectrum. We need to continue to seek and implement improvements in the efficiency of spectrum use (and Australian industry and researchers are great innovators in this field). We need to continue moving spectrum to its highest value use as this changes over time, recognising and valuing the diverse range of monetary and non-monetary contributions that users of spectrum make to the Australian economy and society more generally. The ACMA continues to critically evaluate demand and the need for spectrum across all sectors to better understand the complex and dynamic interaction of social, economic and technical factors that drive spectrum requirements. To this end, we have commissioned two bodies of research - Spectrum Demand Forecasting for Wireless Access Services and the Economic Impacts of Mobile Broadband. This research, the first in an ongoing series of commissioned research, will contribute to the ACMA’s evidence-informed and forward-looking work program with the intent of ensuring that we remain abreast of the game in enabling Australian society to reap the benefits of the digital age. The current framework for managing Australia’s spectrum resource has served us well for almost 20 years. However, in an industry that has undergone significant social, market and political change, as well as rapid technological change, we need to focus on refining and reforming our regulatory toolkit to make sure that regulation does not become an impediment to Australia realising its full potential from spectrum use. A key priority for the ACMA is to be unrelenting in our push for ongoing reform and review of the spectrum management toolkit. To achieve the best possible economic and social benefits from use of spectrum, we will continue to engage and participate meaningfully with the experts in the field - the innovators in all parts of industry.
