mart, flexible, reliable and future-proof, Omnitronics has responded to industry demands with the release of the DX-Altus digital radio management system. Together with the Alto dispatch software, DX-Altus reaches new heights in radio dispatch and interoperability.

The DX-Altus is built on the company’s industry standard IPR technology and is designed to be both internet and user friendly.

Ultimate flexibility is provided by giving users a choice. DMR, P25, Tetra, SIP, PMR and dPMR are just some of the protocols that can work together on the one system. The advanced DRG-100 digital radio gateway translates voice and data into the same language, meaning differing radios and protocols will all be able to connect to the one network. Users are no longer restricted in their choice of protocol nor need to convert their entire network in one swoop. True interoperability is now within reach.

Choice is also available when it comes to the user-friendly GUI, Alto.

Running on a Windows 7 PC, touch screen or keyboard, Alto is completely customisable.

Administrators can choose which functions they wish to include on the system and what operators can and can’t see, right down to button size and colour.

The DX-Altus, DRG-100 and other IP components of the network can also be configured remotely through a web-based system, meaning administrators do not need to go on site.

DX-Altus also gives users the option of using more than just voice communications.

Operators can send and receive text messages, make individual calls and manage emergency

situations more effectively. These functions and more are amongst the many capabilities now available with digital radio protocols such as MotoTRBO and P25.

DX-Altus is built on Omnitronics’ philosophy of modular system architecture, a key aspect of reliability. However, DX-Altus takes this even further by providing complete redundancy.

Firstly, soft degradation has been included. For example, in the unlikely event that an operator’s module fails, a standby module will be switched into operation.In addition, if the Enterprise version of the DX-Altus is chosen, a whole-ofsystem backup can be created with a seamless changeover to the backup system in the event of an outage. For organisations that cannot afford any communications downtime, this feature is invaluable and available in systems with a back-room server, unlike much of the dispatch software currently available.

The DX-Altus is also futureproof. Not only is the system adaptable to any future changes in technology and protocol advancements, it also is easily expandable. As the DX-Altus runs over IP, it is simple to add a repeater or control centre, anywhere in the world.

In addition, the DX-Altus and other IP devices support a range of web-based diagnostic functions. It has the ability to remotely monitor the health of the system in real time using SNMP and other protocols. A number of diagnostic reports are also available to assist with future planning.

Get in touch with Omnitronics to ask for a demonstration.

he concourse - just a walkway to the two seminar theatres the previous year - had exhibition stands all the way along, with the main exhibition hall full to capacity; a testament to how the radio communications industry and end users have embraced this event since its launch in 2007.

In addition to the exhibition, two concurrent presentation streams delivered technical papers and a range of case studies, offering delegates access to over 40 speakers as they enthused about a wide range of issues affecting the industry. From LTE and spectrum planning and allocation, to the contrasting requirements of SCADA applications and the development of stateof-the-art microwave systems in Australia, there was something for everyone and much was covered over the two days of the conference.

The Plenary Theatre’s audience sat in silence during the opening keynote address as Garry Kerr of the Queensland Department of Community Safety presented a critical communications paper wherein he recalled events of last summer and showed footage of devastation wrought upon Queensland by both the floods and Cyclone Yasi.

Next up, Peter Clemons, Director of Communications at Teltronic and Director and Board member of TCCA (formerly the www.radiocomms.com.au

RadioComms Connect has done it again. With over 700 participants from across Australia and all corners of the globe, walking in to this year’s show felt like you were joining in a tight-knit community, buzzing with excitement; a room full of people, passionate about all things radio.

TETRA Association), asked delegates “Does critical communications have a future in the broadband age?” A somewhat tongue-incheek question and one that was answered emphatically during his paper, which looked to open debate on the real issues facing the industry over the next 10 years or so.

Delegate Kevin Jacoby, Department of Defence, said it all, “The information in the conference was very informative and provided in-depth solutions to real-time issues and the very broad range of exhibitors assisted greatly in providing solutions to some of my very obscure requests for a variety of my radio comms requirements.

I will certainly be attending future RadioComms Connect conferences.”

Other hot topics from the technical papers included the release of Phase II of the P25 standard; unlocking the power and performance of radio networks; testing in the digital age; safeguarding lone workers from possible dangers in the field leveraging converging technologies; the NBN rollout and the future of digital mobile radios in the 21st century.

With the venue bursting at the seams, whispers there would be a change of venue for 2012 were confirmed by WF Media’s Event Manager, Paul Davis, “The Etihad Stadium has been a great home for us since 2008 and we’ll be sorry to leave; whilst it’s not purpose built for events

like ours, it’s proved very popular with everyone and has suited us just fine. We do need more space now though, and so, along with the ARCIA Industry Gala Dinner, we’re heading over the other side of the Yarra to the new Conference Centre at the MCEC. With its state-of-the-art facilities and great space, we’ll be well looked after and we hope it’s as popular as the Etihad has been these past few years.”

Held in conjunction with the conference and exhibition each year, the annual ARCIA Industry Gala Dinner and awards night was a sellout too. Almost 500 radio industry professionals gathered at the Palladium at Crown, where high achievers and long-time members of the industry were recognised. For coverage of the night and a full line-up of awards winners, see page 6.

The increased numbers at this year’s conference, exhibition and ARCIA Industry Gala Dinner demonstrated yet again that the radio communications industry is very much on the up and appears to have some way to go. If you didn’t get the chance to attend this year, maybe 2012 at the MCEC will be worth a visit.

For further information see radiocommsconnect.com.au, where a short video of the event is available and access to many of this year’s papers is given under ‘Speakers & Topics’.

he Industry Excellence Award presentations are always a highlight of the evening. In 2011, the most prestigious honour, the Jonathon Livingstone Seagull Award, saw Craig Ross awarded for his significant service to industry, through which he has made huge contributions to charity. One such contribution, highlighted by Ian Miller of ARCIA, was Craig’s efforts to refurbish and donate preloved radio pagers to the Cancer Ward at the Melbourne Royal Children’s Hospital where they were used by parents with children either in the hospital or awaiting procedures, so that they could be contacted and kept informed, enabling families to lead as normal a life as possible.

Martin Cahill, of Pacific Wireless Communications, was also recognised for his involvement with both the radio communications industry over many years and with ARCIA. On the night, Martin received Life Membership of ARCIA for his efforts, some of which are reflected in the growth of the association in recent years. For Martin, his motivation and belief in what was previously seen as a flagging industry are well rewarded when he sees the progress that has been made.

The night was also a showcase for the young, as Dylan Bucktrout was awarded a Sir Angus Tait Memorial Scholarship and Theo Goslett from ComGroup was awarded the Apprentice Trainee Award.

Mobile Masters offered Dylan an apprenticeship in December 2010 and throughout his work Dylan had expressed a keen interest in and passion for learning about the radio industry and is currently studying Certificate 3 in Electronics and Communications at polytechnic.

Theo was awarded for his attention to detail and strong problem-solving skills. In addition to being moved to the Victoria engineering and product development team after only 12 months, he has been recognised by his managers as

having potential to become a leader of the future.

Another newcomer to the industry, Elisha McCann from Kenwood, was awarded the New Talent Award. Elisha was nominated for her dedication in providing excellence in service to her dealer channel, always going above and beyond in her level of service.

Other talented and respected award winners on the night included: Jamie Baker, RF Industries, who received the Peter Wallace Award for his commitment to the industry. Many have come to rely on Jamie and his genuine and helpful advice; Damien Tyrell, the Professional Sales Award for his role at Motorola within the national minerals and energy sectors; Vanessa Rayner, Customer Service Award for her professionalism and willingness to go above and beyond for her customers at Mobile Masters; Nigel Porritt, AA Radio Services, the Technical Excellence Award for demonstrating his skills and talent in many different technical facets of the radio industry over many years and Neil Sutherland, the Engineering Excellence Award for his work at Nixon Communications, including the design and development of a proactive test station for the mining sector.

With both the ARCIA Industry Gala Dinner and RadioComms Connect a sellout this year, the strength felt within the industry about what it has to offer end users is clear. It appears to be a community full of passionate individuals who truly care about what they do and how they do it and, in the end, that can only benefit those looking for radio communication solutions.

Next year the dinner moves to a new home, ready for an bigger night with entertainment, awards and plenty of time for networking with industry colleagues, old and new.

The future of radio Paul Ludvik, NSW business development manager, ComGroup Australia

In my 19 years within the two-way radio industry I have seen many changes and developments. I have seen the transition of radios using crystals, diode matrix boards, EPROMs and DSPs for programming and frequency changes, along with the introduction of data with MDTs, GPS and telemetry within the two-way radio medium.

Paul Ludvik has been in two-way radio for 19 years, starting out as an apprentice communications technician in 1993.

Throughout his career he has worked in various technical and sales roles for many of the country’s leading radio solutions providers. In his current role as NSW business manager, ComGroup Australia, Paul is responsible for managing the local Parramatta branch and serving the NSW market.

8 RADIO COMMS - January/February 2012

Recently the industry has begun to move into the digital world with TETRA and P25 protocols, adding new vibrancy to the radio industry, as the government invests in P25 technology with a focus on interoperability and high-level encryption. Within the Australian market, TETRA technologies are starting to gain real momentum thanks to the changes in the ACMA 400 MHz frequency band, allowing 25 kHz with 10 MHz or more frequency splits within 400 MHz high-density areas to cater for this technology. However, the new kid on the block is definitely DMR, which encapsulates the benefits of both P25 and the TETRA technologies.

DMR features may vary, but most vendors incorporate the following: two timeslots in a 12.5 KHz channel, giving you the benefit of either two voice channels or simultaneous voice and data; some will incorporate duplex telephony while others offer in-built GPS options with their portables coupled with tier 3 offering DMR trunking; and let’s not forget benefits such as digital encryption along with digital audio quality. It was pleasing to see the response to our new Simoco DMR platform at the recent RadioComms Connect show. It’s not hard to see the industry is buzzing about digital radio.

The real challenge, as with any new “The new kid on the block is definitely technology, is the migration and transition DMR, which encapsulates the period. DMR seems to manage this very well. However, the one thing that has been benefits of both P25 and the TETRA underestimated by some adopters is the technologies.” higher cost and current consumption of either microwave links at solar sites to link multisite systems together, or the lack of DSL type services within the rural base sites. This has possibly been the hardest obstacle to overcome with the migration to digital, but investments that are needed by organisations and industry will provide major benefits for years to come, and has now become the norm when planning a new radio system.

So the digital revolution is certainly alive and well, as we are seeing new players within our space. And these newcomers are our friends from the IT world.

With the integration of IP-based technology in the form of consoles, remote configuration and diagnostics, coupled with VoIP linking, we are seeing an RF control with an antenna fitted within an office being swapped out for a PC with a console application connected via DSL-type services.

The bridge between two-way radio, cellular and IT is becoming more and more apparent, with the onset of LTE or 4G adding to the mix, with the possibility of one day having two-way radios as an application on your smartphone. So who knows what is around the corner, but whatever the future brings, it is important that the radio industry embraces it and makes an investment in skills and training, so that we can better manage this transition and have some control of our market and destiny.

xperts from Kingston University, London, have developed a solution to ensure breakdowns in communication are a thing of the past for emergency workers responding to disasters.

A team led by Dr Christos Politis has designed an internet-based technique to keep rescuers and their central control room in touch independently, rather than using central wireless access points or the TETRA police radio system.

The app, which can be used on an iPad or other personal digital assistant, will also allow emergency service workers in Britain to talk to counterparts across Europe on a secure system.

The research, funded by the European Union’s PEACE project, built on existing work into mobile networks, known as MANETs. These are networks of mobile devices which work independently and are connected by individual wireless links.

Rather than connecting through an external internet network, the new technique allows rescue workers to set up an independent communication system designed for their specific purposes at the scene whatever the situation or location - be it an underground tube station or next to a collapsed office block.

The design allows one of the mobile devices carried by a rescue worker to act as the super-node - a bit like a mini satellite - letting other mobile devices communicate with each other. As soon as a device passes a virtual intelligence security check, it can start to find others in the location.

Each worker can then talk or send video or data to individual workers or entire groups.

The devices can also be used to work with new sensors being created by research partners in the PEACE project.

“In the future the technology will also be able to act as sensors and pick up humidity levels, workers’ heart rates, temperatures, movement and pass these on to a central operator,” Dr Politis said.

46-position installation of Zetron’s Advanced Communication (Acom) system is in its final stages of deployment and testing at the Queensland Emergency Operations Centre (QEOC) near Brisbane.

Two main operations are housed at QEOC: the communications centre and the State Disaster Operations Centre. The Zetron Acom system installed at the communications centre will serve as the command-and-control point for the Queensland Ambulance Service, the Queensland Fire and Rescue Service, Queensland Corrective Services and Emergency Management Queensland.

Colin Allen, Operations Manager, QEOC, Queensland Department of Community Safety commented: “The new Acom system meets our operational needs well and gives us excellent

control and functionality over our radio systems.”

The Acom system for the QEOC communication centre includes: 46 operator consoles; 10 analog PABX/PSTN interfaces; 156 analog radio interfaces; 10 utility audio interfaces; 46 PABX phone-to-console interfaces; and 10 digital, long-term logging interfaces that use E1 links from all console and radio lines.

“We worked closely with the QEOC to deliver a system that would meet their unique and exacting specifications,” said Zetron Australasia Vice President and General Manager, Ranjan Bhagat. “Zetron is committed to providing solutions that support public safety services throughout Australia and Asia and that also reflect a thorough understanding of local requirements.”

A name change for TETRA Association

T

he TETRA Association has changed its name to the TETRA + Critical Communications Association (TCCA).

The name change is said to promote the development and adoption of common standards and solutions for the users and providers of critical communications worldwide.

This change is in response to the growing demand from professional mobile radio (PMR) users for mobile broadband services. This demand may be satisfied by the capabilities of future and complementary technologies such as LTE and/or WiMax. TCCA chairman Phil Godfrey commented, “Changing our name gives us the scope to better address these new opportunities whilst protecting the huge investment of users and industry in TETRA technology and systems.

“This change in no way diminishes our focus on TETRA. TETRA will be the primary, most important technology for mission- and

TETRA + Critical Communications Association (TCCA) business-critical voice and data services for at least the next decade, and we will continue to develop, promote and protect the TETRA standard worldwide.”

Enhanced protection for quiet zone

L

he Australian Communications and Media Authority (ACMA) has enhanced the radio quiet protections for the Mid West Radio Quiet Zone (RQZ) in remote Western Australia (near Boolardy Station), around 200 km east of Meekatharra.

whilst offering ambulance organisations increased efficiency and faster response times in answering emergency calls. Voice and data messages are immediately and reliably relayed, saving precious seconds in answering calls.

The advantages offered to ambulance crews and control rooms by the ambulance solution enables crews to improve their service to the public.

DMR completes test sessions

T

he Digital Mobile Radio (DMR) Association has completed an interoperability test session in Milan, Italy.

Testing of the DMR repeater and simulcast network infrastructure of Selex Communications with Hytera’s DMR terminals was carried out following the association’s interoperability process that defines a list of interoperability tests, suitable test methodology, testing laboratory criteria and a test result verification process for both conventional and trunked modes of operation.

Tests performed include voice calls (individual, group, broadcast and emergency calls), call alerts, radio check, remote monitoring, emergency alarm, radio enable and disable.

In addition, the association announced that DMR category one member Vertex Standard will hold an interoperability test session open to manufacturers for DMR-compliant products in the week of 13-18 June. This brings to five the number of DMR manufacturers actively involved in formalised interoperability testing.

ast year, the new digital communication system deployed by the five authorities responsible for all hospital and emergency services in Denmark became operational, using Sepura TETRA radios. This is part of the migration from their legacy analogue infrastructure onto SINE, the Danish national TETRA network.

Sepura celebrates its 100% market share in the Danish ambulance market with Radiocom, Sepura’s valued distribution partner in Denmark.

Over 550 ambulances are now equipped with Sepura vehicle and hand-portable TETRA radios enabling critical voice and data communications between all paramedics and their command and control centres in each of the five Danish regions.

The first phase of the migration to TETRA technology follows the recent Scandinavian success of Sepura’s ambulance solution with three key Swedish health authorities.

The ambulance solution delivers swift and reliable communication to health service operatives in Denmark. It enables faster response times and more efficient service provision by combining two-way radio communications, messaging, mobile telephony and mobile data.

Sepura radios provide reliable uninterrupted reception, clear audio and use of data messaging

The RQZ was established in 2005 to provide an environment that protects highly sensitive equipment, used for radio astronomy, from unwanted radiocommunications signals.

These arrangements protect the radio telescopes currently in place at the Murchison Radioastronomy Observatory, as well as those proposed in the Australian-New Zealand bid to host the square kilometre array (SKA).

“A clear regulatory framework to support radio quiet arrangements will further assist Australia to create the world’s best radioastronomy facility,” said ACMA Chairman, Chris Chapman. “This will provide a platform that should be ideal for future radioastronomy projects, including the € 1.5 billion SKA project.”

Mr Chapman said the new protection measures provide greater clarity and certainty to the arrangements that protect radioastronomy services in the RQZ. “The new measures continue to provide for radio quiet while supporting the use of spectrum by other users and placing the lowest feasible burden on industry in the region,” said Mr Chapman.

He said the new protection measures will not significantly change the nature of spectrum access and radio quiet arrangements in the Mid West RQZ. “This will enhance protection for the RQZ by upgrading the existing statements of ACMA administrative practice to more formal regulation,” Mr Chapman said.

The ACMA has released a response to submissions paper that outlines the rationale behind the final package of measures.

Floods, cyclones and radio communications While radio played a major role in alleviating some of the worst aspects of Queensland’s 2011 floods and cyclones, there were times when the technology was stretched to its limits. Here Garry Kerr, manager of system support devices at the Queensland Department of Community Safety, describes some of the challenges that face radio operators and technicians during the crises.

D

uring the worst part of the Queensland floods, the Department of Community Safety and other public safety agencies used two-way radio to support front-line incident response and recovery. The department delivered ambulance, fire, emergency and disaster management services through a single agency.

Kerr told his audience that, with three quarters of the state declared a disaster zone, ambulance and fire received 14,349 Triple Zero emergency calls, which on average were over 1500 more calls than usual. There were over 560,000 transmissions on ambulance and fire radio networks across the state during the flood period.

The ambulance service in the Brisbane region handled 5236 emergency Triple Zero calls. The radio network managed 44,734 radio transmissions, totalling 143 hours of talk time, or 74% utilisation, which was 30% above the average.

All radio networks in Brisbane and across the state handled the workload well, with all operational ambulance and fire radio sites maintaining serviceability

during this time. The solar sites with wind generators functioned well, keeping the batteries charged and operational he said.

Queensland was still recovering from the flood when tropical cyclone Yasi crossed the coast at Mission Beach just after 2.00 am on 3 February 2011.

The cyclone unleashed winds of up to 290 km/h. The hardest hit communities were Cardwell, Tully, Innisfail and Mission Beach, with major flooding in the Townsville, Ingham and Giru areas.

At this time, the Firecom communications centre in Cairns undertook a controlled handover of the northern region radio network. In addition to this, the Triple Zero telephone calls to Firecom Townsville were programmed to immediately divert to other Firecoms around the state with no delay to call response times.

The hand-over of control worked by connecting both the Far Northern region and Northern region networks together at the Mt Cudmore radio site.

Both networks were configured for wide-area operation so, when Cairns Firecom keyed a repeater in its radio

16 RADIO COMMS - January/February 2012

network, all repeaters in both regions keyed simultaneously, providing one workgroup all-informed capability. Another option available was to use the radio management systems to activate RoIP services to connect into each region’s networks.

Swift Water Rescue teams The Swift Water Rescue teams that worked during the disasters relied heavily on radio communications. The teams rescued people from swiftflowing water and floodwater and encompassed areas such as natural waterways, weirs, stormwater drains, floodways and inundated streets.

Rescuers worked under life-threatening conditions and radio communication devices needed to be ruggedised, reliable and as waterproof as possible.

The Swift Water Rescue teams used waterproof radio harnesses, helmet coms and hands-free devices. Rescuers also used whistle, voice and hand signals to communicate with incident command due to the significant environmental noise. www.radiocomms.com.au

Mt Mackay radio site provides coverage to Tully and adjoining areas.

501 Tango QFRS incident command unit

Establishing incident communications Although many networks had run into complications, the fire radio network in the Brisbane region operated normally as a conventional wide-area PMR network. During its operation, when one radio site repeater was activated, all repeaters across the region were activated simultaneously.

When establishing incident communications, one consideration was to isolate a selected radio repeater from the existing network. Alternatively, preconfigured dedicated radio communications channels could be allocated specifically to incident and emergency situations.

This method worked well as it ensured uninterrupted communications at the incident zone, and allowed the operations radio network to function as normal.

Townsville ambulance service backup communications The ambulance service in Townsville had a different story. As part of its planning, it had activated its backup communications centre that provided support services to the main communications centre.

In the hours after Yasi crossed the coast, there was no communication with Palm Island and Ingham. This suggested there was a problem at the Townsville www.radiocomms.com.au

Castle Hill radio site that had a UHF talk-through repeater service for ambulance to use throughout the Townsville area, Kerr said.

For this area, ambulance operations were able to use the Mt Stuart repeater as a backup to Castle Hill. A stand-by radio system that communicated to Palm Island was installed at the communications centre and, using the standby system, radio communication was established between the ambulance communications centre and Palm Island.

Ambulance operations in Ingham changed their channels to Palm Island to communicate with Townsville. With all appropriate business continuity plans and procedures in place, the ambulance service continued operations as normal.

501 Tango cyclone preparations Fires incident command unit 501Tango was prepared for the cyclone. The unit travelled from Brisbane and set up

a staging area and command post in Mareeba near Cairns. After Yasi passed through, Tango travelled to Tully and was placed into operational readiness for any specific incident requirements such as search and rescue, particularly swift-water situations.

The Tango and crew managed and provided support for large-scale emergency incidents. Services included email, printing, mapping, VoIP, external cameras, radio communications, wireless capability and computer-aided dis-

patch. The unit also supported NextG data services, video conferencing, audio visual and satellite connectivity.

Recovery operations The recovery operations included inspecting all radio equipment for damage. Locations included radio sites, ambulance, fire and SES stations and it took 22 days after Yasi subsided to complete all site inspections.

Access to radio sites was one of the biggest challenges. Technical teams

18 RADIO COMMS - January/February 2012

attempting to reach various radio sites were delayed sometimes by inaccessible roads and tracks and, in some cases, roads that were washed away altogether. In some cases helicopters were used to help technicians reach radio sites when road access was not possible.

An inspection following helicopteronly access showed that the antenna towers had been damaged by high winds although the radio equipment remained operational. The wooden towers are being replaced with steel monopole towers, he said.

The Mt Mackay radio site, normally managed from the far northern region operations, provides radio coverage to Tully and adjoining areas, providing services to ambulance, fire, EMQ, Queensland police, electrical utilities and many commercial businesses.

Kerr mentioned that overall the radio sites worked well. While some sites lost serviceability during the cyclone, the Queensland Department of Community Safety’s business continuity planning, incorporating the use of redundant radio services and dedicated incident channels, allowed the operational divisions to continue their service delivery to the communities, without compromise.

RF measurement instruments Aeroflex has expanded its S-series family of benchtop RF measurement instruments. Two S-series digital signal generators, the SGD in both 3 GHz and 6 GHz models, and two vector signal analysers, the SVA, available in a 6 GHz and a 13 GHz model, have been added.

The SGD-3 and SGD-6 both feature +13 dBm output power, with a +20 dBm option. They incorporate an IQ modulator with 300 MHz RF bandwidth, which can generate wide bandwidth modulated signals. A dual-channel arbitrary waveform generator (AWG), operating at up to 250 MS/s, with memory options up to 4 GB, offers faster waveform generation and the ability to store multiple signals. The embedded IQCreator waveform generation tool enables the user to set up a modulation scheme and create an AWG file using modulation templates.

The SGD has low single sideband phase noise of -135 dBc/Hz at 1 GHz offset, and a frequency settling time of 100 Âľs, enabling accurate receiver testing with a significant reduction in measurement time and cost. The high dynamic range of the IQ modulators provides for an adjacent channel leakage ratio of -71 dBc on WCDMA signals, enabling the user to design and test amplifier performance to higher specifications.

The extended frequency range, up to 13 GHz for the SVA-13, allows the instrument to be used for analysing second harmonic performance of signals in popular communications bands. A wide maximum instantaneous bandwidth of up to 90 MHz makes it suitable for measuring and analysing both narrow- and wide-bandwidth communication systems.

Peak signal power levels up +30 dBm can be input directly to the instrument. With a maximum sensitivity of -148 dBm/Hz, very low level signals can easily be discriminated from noise when measuring transmitter spurious outputs.

rf testing

Pushing radar designs to the limit with realistic signal scenarios Beate Hoehne, product manager high-speed AWGs, Agilent Technologies

In the development of next-generation radar and electronic warfare systems, typical test scenarios include simulations such as low-observable signals mixed with ground clutter and environmental interferers.

A

ddressing these demanding scenarios requires an arbitrary waveform generator or signal-scenario generator that has two key attributes.

The first is a design that provides wide bandwidth and high resolution simultaneously. The second is built-in capabilities that support the creation of long, complex signal scenarios.

The Agilent M8190A SSG has 14-bit resolution at eight gigasamples per second (GSa/s) or 12-bit resolution at 12 GSa/s, and offers two modes that ensure good signal fidelity at high frequencies.

It also enables long playback time with up to 2 GSa of waveform memory and a variety of sequencing capabilities.

Today, typical AWGs force system creators to make a trade-off between units that offer either wide bandwidth and low resolution or limited bandwidth and high resolution.

The respective levels of performance in both bandwidth and resolution depend www.radiocomms.com.au

on the digital-to-analog converter used in the AWG. Bandwidth is limited by the DAC sample rate and accuracy is affected by the quality and performance of the analog components used inside the device.

Agilent researchers have developed a way to eliminate the spurious signals (spurs) and distortion present in typical DAC designs. The approach focuses on the beginning of the signal-generation process, reducing the need for filtering at the end of the signal chain.

This is based on two key ideas. One is to let switched current sources settle within the DAC. The other is to resample the signal with a special low-noise clock before outputting the simulated signal.

The resulting DAC output provides spurious-free dynamic range of up to 80 dBc, which is much better than most other designs can achieve.

At 8 GSa/s, the DAC typically delivers 75 dBc SFDR (excluding second and third

harmonics) across an output frequency range of 0 to 3 GHz. One of the most important design choices was the decision to use a lowtemperature, multilayer ceramic substrate.

A package with many layers is necessary to meet specifications for noise and spurious response.

The net result is good performance at high frequencies. As implemented in the M8190A SSG, the ability to achieve high resolution at high frequency gives system developers greater confidence that they are testing their design, not the signal source.

To create realistic signal scenarios, an AWG or SSG needs more than raw DAC technology. Three additional attributes enable sufficiently long playback times: waveform memory, advanced sequencing capabilities and real-time access to individual memory segments.

The SSG can be configured with 128 MSa (standard) to 2 GSa (optional) of

January/February 2012 - RADIO COMMS

rf testing

waveform memory per output channel.

With 2 GSa installed, the maximum playback time of a single waveform is 180 ms at the highest sample rate.

The absolute quantity of waveform memory is important. However, using the available memory efficiently enables a concept called memory gain. Typical AWGs consume memory space by requiring multiple occurrences of identical segments that are repeated within a sequence.

In the M8190A, sequencing capabilities such as stepping, looping and conditional jumping make it possible to create such segments once and re-use them programmatically as needed. These capabilities can be applied to waveforms or waveform sequences.

Specific to the M8190A, up to 256,000 segments can be stored in memory and up to 4 billion loops can be defined for each segment.

Beyond the sequencing of individual segments, it’s possible to set up a series of advanced sequences. This enables users to build and playback highly complex scenarios comprising one or more sequences.

The third attribute is a hardwarebased dynamic sequence-control input.

This eight-bit bus is used to enable immediate or synchronous switching between segments or sequences. Immediate jumps interrupt the active segment or sequence before completion; synchronous jumps wait until the active segment or sequence is completed.

The actuating signals can come from the unit under test, another instrument within the system or any other external device.

Software is a fourth element in the solution set. Examples include Signal Studio from Agilent, MATLAB from MathWorks and LabVIEW from National Instruments. These provide an environment for signal creation and the results can be downloaded to the SSG’s memory for playback.

Two versions of Signal Studio are especially relevant in aerospace and defence applications. Signal Studio for Pulse Building (N7620A) simplifies the creation of complex pulse patterns for testing radar receivers. SS for Multitone Distortion (N7621A and N7621B) can be used to create multitone and noise power ratio signals for testing satellite transceivers.

Another useful application is Agilent’s SystemVue electronic system-level (ESL) design software. The Radar Model Library for SystemVue (W1905) includes predefined radar signals that can be

“The resulting DAC output provides spurious-free dynamic range of up to 80 dBc, which is much better than most other designs can achieve.” selected and loaded into, for example, the M8190A. The library also provides more than 35 highly parameterised primitive blocks and higher-level reference designs that can be used to create a working radar system.

The block set and its example workspaces serve as algorithmic and architectural reference scenarios to verify radar performance with a variety of signal conditions: target and radar cross-section scenarios; clutter conditions; jammers and environmental interferers; and different receiver algorithms.

AWGs and SSGs provide important benefits in the development of present and future radar and EW systems. The greatest technical advantage is the possibility of creating simulated signal scenarios with enhanced realism. This helps minimise the need for costly flight testing and enhances the flexibility of groundbased testing.

From a business perspective, greater flexibility makes it possible to test multiple radar or EW designs with a single measurement system, enhancing system re-use. Further, modules such as the M8190A are based on commercial, offthe-shelf technology such as AXIe. A modular approach helps reduce the size, weight and physical footprint of the test system.

24 RADIO COMMS - January/February 2012

To address a variety of measurement needs, the M8190A offers three software-selectable output paths: direct DAC, DC amplifier and AC amplifier.

The direct DAC path is optimised for the generation of in-phase/quadrature signals that offer superior SFDR and harmonic distortion.

Key attributes include 5 GHz bandwidth, amplitude range of 350 to 700 mV peak-to-peak (fixed offset), differential output and rise/fall times of about 50 ps (20 to 80%).

The DC amplifier path is optimised for applications that require serial data and time-domain measurements. Important capabilities include differential output, amplitude range of 600 mV to 1.2 V peak-topeak (from -1.0 to +3.0 V), rise/ fall times of about 35 ps (20 to 80%) and a Bessel-Thomson filter to ensure low overshoot.

The AC amplifier path is designed for the generation of direct IF/RF signals. This output is single-ended and AC coupled with a power range of -10 to +10 dBm.

Mixed domain scope Tektronix has introduced what it claims is the first mixed domain oscilloscope that delivers the functionality of a scope and a spectrum analyser in a single instrument.

The MDO4000 mixed domain oscilloscope series gives users the ability to capture time-correlated analog, digital and RF signals for a complete system view.

More than 60% of oscilloscope users also use a spectrum analyser to troubleshoot embedded system designs with integrated wireless functionality, requiring them to work in both the time and frequency domain.

The instrument allows users to capture time-correlated analog, digital and RF signals across four analog, 16 digital and one RF channel.

The RF input frequency range extends to 6 GHz and provides a capture bandwidth of ≥1 GHz at all centre frequencies, 100 times wider than other spectrum analysers. Users can see up to four decoded serial and/or parallel buses at one time on the same display.

Due to this time correlation between domains, engineers can now make accurate timing measurements to understand delays and latencies between command/ control events in their design and changes in the RF spectrum.

The oscilloscope also allows designers to see the RF spectrum of a signal at any point in time within a long acquisition to see how the spectrum changes over time or with device state.

By moving the Spectrum Time throughout the time domain acquisition, designers can see the RF spectrum for any point in their acquisition while simultaneously seeing their analog, digital and/or decoded buses at the same point in time.

Similarly, RF time domain traces are used to show how the amplitude, frequency or phase of the RF input signal changes relative to time. The RF time domain traces are shown in the same window as the analog, digital and serial/parallel bus decoded waveforms, providing instant insight into device operation.

In addition to the standard RF power level trigger, an optional module (MDO4TRIG) allows additional trigger types to use the RF power level as a source, enabling users to further isolate an RF event of interest.

Users can trigger on a specific pulse width, or look for a timeout event or runt, or even include the RF input in a logic pattern defined along with the analog and digital channels.

This ability to trigger on whatever the user is interested in regardless of whether it’s analog, digital, RF or some combination is a claimed industry first for the series.

Once connected, every audio characteristic can be measured.

Key features include 30+ one-click audio measurements (including all standard weighting filters), onemillion-point FFTs, real-time oscilloscope monitoring, custom reports, statistical calculations and quasianechoic acoustic measurements.

With 21 measurements in 1 s, the analyser is suitable for Bluetooth production test.

Peltor’s DECT-Com II radio system delivers full duplex intercom communication for up to nine members in digital privacy. Operating in the 1.8 GHz DECT spectrum, the radio allows users to talk easily in full duplex within a team across a site.

Enhancing clarity and ease of use the system also allows full interoperability with land mobile two-way radios and establishes a gateway path with a mobile radio and then provides full radio access to other DECT-Com users.

For example, a fire appliance could have a dedicated dispatch radio in the vehicle connected to its controller. All occupants of the vehicle could be connected directly to the radio via the DECT-Com II units while in and out of the vehicle. The users are also communicating as a team in full clarity duplex.

Selected two-way radio traffic is instantly broadcast on the units and they are specifically designed for high-noise environments.

Shared networks: a blueprint for success Malcolm Keys, CEO and Brett Savill, Director, Airwave Solutions Australia

Sharing public safety communications networks can provide many advantages for a range of organisations. However, to ensure that individual agencies’ requirements are met, it is imperative that the balance between core and non-core users is optimised.

S

haring a radio network between public safety agencies, such as the police, fire and ambulance services, makes considerable sense, to facilitate inter-agency communication and cooperation and reduce the need for duplication of infrastructure resources. There are also many advantages for non-emergency service agencies, both in the public and private sector, using the same shared network.

However, for a shared communication infrastructure to be used to its best advantage, a number of parameters need to be considered to ensure all users’ needs are met, and no one agency’s requirements are compromised. Considerable care needs to be taken with the contractual arrangements to ensure that each agency’s contribution is a true reflection of its actual usage of the network.

Among the lessons learned by Airwave’s experience in the design, installation and management of a number of shared public safety networks in the UK, Europe and Australasia, is the simple fact that different types of agencies have different communications requirements.

While a TETRA or P25 network is capable of meeting these varying agencies’ needs, more so than a standard mobile or commercial-grade private mobile radio (PMR) network, it is also more expensive. As such, it is important that users actually value the capabilities and features of the system over and above what a mobile or PMR alternative can deliver.

The key communication requirements of the police - coverage, capacity, availability, security, resilience, and terminal functionality - became the fundamental design criteria for the finished UK public safety network.

“Data capability is important and the security of data transmission is imperative to meet the data protection requirements of the health sector.”

Differentiation of delivery The UK network has demonstrated a clear differentiation between the needs of the principal core users. The public safety network was initially designed for the police and its key requirements became the fundamental design criteria for the finished system. Additionally, the system has a data capability.

While the ambulance service requires very similar coverage, availability and resilience to the police, security of voice traffic is a lesser consideration. By contrast, data capability is important and the security of data transmission is imperative to meet the data protection requirements of the health sector.

Due to the smaller nature of the agency, the ambulance service also requires a fully managed end-to-end service over and above the network services provided to the police.

In comparison, fire service requirements are notably different to those of the police and the ambulance. The fire service not only values vehicle-radio coverage in preference to handheld capabilities, but it also places much less importance on security. Availability and resilience remain crucial elements - both for voice and data - with additional ‘power resilience,’ an element specific to the fire service.

Beyond these front-line emergency services, cost becomes more crucial, with a greater need to balance the capabilities of a TETRA/P25 network over a cheaper mobile or PMR alternative. Here, non-core users include local councils, government departments and public transport agencies.

Importantly, these smaller agencies each see benefits in using a dedicated network that links into the larger agencies.

The Cabinet Office is a prime example of an agency in the UK that sees value in interoperability with incident command of the police and other security forces.

Other examples include the Maritime and Coastguard Agency - which is interested in general in-shore communications with the police, ambulance and RAF - and the Prison Service, that wants to interoperate with the police.

Equally, the Environment Agency wants interoperable communications with a number of agencies to facilitate the coordinated responses to environmental incidents, such as floods, snowstorms and waste spills.

Even the Royal Society for the Prevention of Cruelty to Animals can benefit from the ability to communicate seamlessly with larger agencies. Each of these organisations sees a unique benefit to being able to coordinate its communication with other agencies in a manner not possible if they had opted for a traditional cellular communication solution.

The diverse array of users similarly demonstrates differing agency requirements. Coverage, security, availability, resilience and interoperability are all still valued by non-core users, but to varying degrees for each end-user. Overall, the key combination of coverage, availability and resilience has been the overriding factor for most users to select the TETRA/P25 option. www.radiocomms.com.au

interoperability

Setting the service level These non-core users also differ from the police, fire, and ambulance services in the nature of their contracts. Typically, the expected provision of network services and features is defined for smaller users under a standard contract format. These contracts also provide the opportunity for ‘add-on’ contract services, such as terminal management, control room services, terminal numbers and fleet mapping, plus options for further tailoring of the system.

By comparison, the core users have the added advantages that service level agreements (SLAs) deliver. These, similarly, include an indication of the range of services and included features the user can expect from the network. However, every SLA is different and reflects the unique service needs of each agency. For example, the UK fire and ambulance contracts include the provision for management of terminals, services and control rooms, as well as network services, whereas the police only require that network services be provided.

Under an SLA, any failure to meet an agreed service level results in an accrued service credit. This can be reimbursed back to the agency directly, although more commonly the credit is used to improve the infrastructure in order to mitigate the chances of similar service level deficiencies in the future.

Allocating operational costs With each agency’s use of the network, it becomes essential that operational costs are apportioned fairly, and a number of models exist to facilitate this process.

By ensuring a transparent and itemised relationship between price and service deliverables, the political processes, regarding funding, can be simplified and claims of unaffordability can be successfully mitigated.

While apportioning operational costs can be difficult, the allocation of capital costs can present a greater challenge. As the agency for which the UK public safety network was primarily designed and established, the police have necessarily borne the brunt of the initial capital costs. When the fire and ambulance services subsequently began using the system, they were, in effect, able to have the benefits of an established infrastructure. The main capital cost faced by the fire and ambulance services has been to cover the 30,000 additional radio sets required and to tailor the capacity and coverage of the network to meet their own requirements.

To share the capital costs, the ideal scenario would be for all agencies to adopt the new communications package in paralwww.radiocomms.com.au

“Each [organisation] sees a unique benefit to being able to coordinate its communication with other agencies in a manner not possible if they had opted for a traditional cellular communication solution.”

lel. Realistically, however, it is inevitable that one agency will take the lead as the ‘anchor’ organisation for the new network.

As the largest, most sophisticated agency - and the one with the greatest requirements - the police make an ideal anchor agency in most countries or states.

Whichever agency takes the lead, the services and features they select will, in effect, become the benchmark for additional users. As new agencies subsequently join the network, they will then be able to choose which features of this established network they do and do not need and which add-on features they require.

The fire service places a high value on availability and resilience - especially ‘power-resilience’ - for both voice and data communications.

The ambulance service requires very similar coverage, availability and resilience to the police, with an additional requirement for a secure data capability.

The tender process In the UK, each agency went through a user-requirement phase before going out to tender. This was a more onerous process for the police, as the pioneer client for the network. For the fire and ambulance services, the network capabilities were a better known quantity, and negotiation revolved around variations to the established police platform to meet each individual agency’s requirements.

For the smaller contractees, far greater standardisation was offered. The police contract enabled Airwave to offer services to other authorised users in return for a slightly discounted overall price for police users. A discrete product - Airwave Direct - was developed to enable services to be offered to small scale agencies, with a framework in place to make specialist capabilities available, such as dispatching, control rooms and mobile data. However, it was only possible to meet the needs of these small agencies with the anchor tenant already in place.

Where possible, it has been advantageous to allow for service differentiation - with prices to match - to ensure users are not overpaying for services or features they don’t need. In practice, it is difficult to unbundle the standard features of the

TETRA or P25 network functionality and the savings to be made here are limited, especially given the fact that coverage remains the biggest cost driver. Rather than deconstructing the basic network provision, most differentiation has actually been achieved by adding additional services - including capacity, coverage, security, resilience, tighter SLAs, mobile data solutions, telemetry, and end-to-end service management.

Outsource management The end-to-end service provision option ensures that users can completely outsource management of their mobile communications solution. This further ensures that upgrades are better coordinated between the network, terminals and control rooms. Research recently conducted by Airwave’s sister company Arqiva concludes that the main benefit to outsourcing such non-core services is cost savings.

A typical mid-sized regional police force, for example, can potentially have cost savings of around $900,000 over a four-year period by outsourcing its communications services. This equates to the cost of 16 additional officers on the beat for five years, two officers redeploying from communications management to frontline duties and total staffing savings over four years of $500,000.

Cost saving potentials are a recurring theme with shared networks, both for individual organisations and collectively through sidestepping the need to replicate communications infrastructure for each separate agency. While care needs to be taken to ensure that, as additional organisations come on board, the quality of the service for core users is not compromised, the reality is that, as more agencies use the network, the greater the infrastructure investment will be and the better the service enjoyed by all. Shared networks allow users to enjoy unprecedented inter-agency interoperability, while delivering unparalleled levels of coverage, availability and resilience.

INDUSTRY TALKING It has been a busy few months with the ARCIA elections, production of the annual report, RadioComms Connect and the annual gala dinner in Melbourne, formation of state-based subcommittees, and development of more regional events in Sydney and Brisbane.

Many thanks to outgoing members of the committee Steve Reining and Steve Kennedy. Thank you to Alistair Tibballs for his work as treasurer and congratulations to incoming members. David Cox is now treasurer and Bob Rogers is now secretary.

The Annual General Meeting saw a change to the ARCIA constitution which allows for up to 12 committee positions, in addition to the executive. This will allow state subcommittees to be formed that can then determine their own action plans and make representations to the executive for budget and support.

So far we have: Melanie Arnott, WA; Jeff Perry, SA, with Dennis Liddicoate; Anthony Blyth and Devran Roberts, Qld; Martin McLeod and Hamish Duff, NSW; and Alan Clarke, Neale Joseph and Alistair Tibballs, Victoria. Chris Stapleton leads accreditations. Bob Rogers leads the education and training committee. Events are managed by the regional groups. Ian Miller heads technical and spectrum management with Noel Higgins, who also chairs the RC4 and RC6 standards meetings and provides keen insights into the impact of any spectrum review proposals. Jamie Baker as ex-officio committee member provides an ambassadorial role in promoting ARCIA. Congratulations to all the Excellence Award winners at the annual gala dinner and many thanks to the sponsors and ARCIA committee members who helped out on the night.

It was particularly gratifying to see the quantity of nominations this year in every category and, more importantly, the quality of the representations that made the task that much harder in making the decisions of who would be recognised as outstanding performers. This program has gone from strength to strength as the industry realises the importance of peer recognition and the depth of talent in so many different areas.

Another program that is gaining momentum is the Sir Angus Tait Scholarship, jointly supported by ARCIA, Tait Communications, Westwick-Farrow Media and most recently, Omnitronics. The most recent scholarship was won by Dylan Bucktrout, an apprentice from Mobile Masters in WA. Congratulations to Craig Ross for his induction into the Jonathan Livingstone Award. This was another stirring and humbling event at the annual dinner.

Finally, many thanks to ARCIA’s sponsors and partners for 2011: Motorola Solutions, Kenwood Electronics, AA Radio, GME, Radlink, RFI, Tait and RadioComms Connect.

RADIO Zetron system dispatches ‘Flying Doctor’ to Australian Outback

A

digital console radio system has replaced the Australian Royal Flying Doctor Service’s (RFDS) 1990s radio installation.

This latest system from Zetron is the DCS 5020. It integrates telephony and radio, call handling, monitoring and logging and brings all these functions into a single operator interface.

Installed in the Broken Hill base of the RFDS, the system supports up to 30 channels and 16 screen-based operator consoles, each of which includes a host PC, video monitor and desktop speakers.

These operator positions are provided along with multiple radio inputs over HF, VHF and UHF and phone circuits.

This latest installation replaces a 17-year-old Zetron 4010 radio dispatch console and a combination of HF, VHF and UHF radios.

Providing information and recommendations to the RFDS was AA Radio Services, based in Melbourne.

AA Radio Services project manager Ian Miller says the company was first contacted to help repair and maintain the user’s existing system. They were then asked to provide a quote for a new system to be installed.

Miller explains how the RFDS’s DCS5020 system was implemented.

“The system was designed and assembled in the AA Radio Services workshop in Melbourne,” he says. “We then transported it to the client’s location about 700 km away. Our technical crew installed and commissioned the system over a period of five days, then made a follow-up visit to refine the system to meet the user’s unique requirements.”

“The daily operations of the RFDS could not be compromised. We often had to stand back and allow the operators

to complete their tasks before we could proceed with ours. But these challenges were all easily overcome because we had planned and prepared for them,” says Miller.

The RFDS has a long history of radio innovation beginning in the 1920s with the famous pedal radios under the inspiration of RFDS founder the Rev John Flynn. Originally designed to last a year, the system went from strength to strength even during the depression and World War II. Today, the RFDS is one of the largest aero-medical organisations in the world.

It delivers primary healthcare and 24-hour emergency services to people living in rural and remote areas of Australia. The organisation now has a fleet of 60 aircraft operating from 21 bases across the country. It provides medical assistance to over 275,000 people each year - about one person every two minutes.

Separated into four geographic sections; Central Operations, the Queensland Section, Western Operations and the South Eastern Section, each section has several bases from which the service’s aircraft are operated and dispatched.

Broken Hill is the main base for the South Eastern Section. It services NSW and parts of neighbouring states in an area of about 640,000 km2.

The RFDS has become an Australian institution that has led to better health and treatment for thousands of outback residents. Each year the Broken Hill base sees over 13,000 patients, conducts over 1600 clinic sessions and transports over 900 patients by air.

Modern radio communications should see the Royal Flying Doctor Service carry on its medical mission around the country for years to come.
