Leveraging 5G
Faster, more stable, and more secure wireless connectivity
By Tracy Barbour
5G technology is having a significant impact at Spawn Ideas. The Anchorage-based advertising agency is operating in hybrid mode: employees work two days in the office and three days from home, with about one-third of them completely remote. Most of the company’s thirty employees take advantage of 5G wireless service to communicate with colleagues and clients across Alaska, Washington, Montana, Iowa, Oregon, and Washington, DC.
The availability of 5G makes hybrid and remote work more feasible for Spawn Ideas. It enables employees to have ubiquitous and secure connectivity. For example, many use a mobile phone as a WiFi hotspot for their laptop when conducting Zoom calls or doing other business away from the office. With 5G, they can work wherever they are, which is a huge advantage—and luxury, according to President and CEO Karen King. “We are really spoiled by 5G’s data transfer speeds,” King says. “We’re used to low latency. We’re used to the stability and reliability of having a 5G [compatible] phone and service.”
Spawn Ideas uses wireless service from GCI which, incidentally, is also a client of the agency. “Living in Anchorage, I feel that I have all of the advantages with service from GCI that anyone else has in other US locations,” King says, referring to the speed and dependability of 5G cellular service.
The use of 5G technology has been steadily increasing among consumers and companies like Spawn Ideas. By 2025, 5G networks are expected to have more than 1.7 billion subscribers globally, according to Global System for Mobile Communications, which represents the interests of mobile network operators worldwide. Most cellular carriers began ramping up their efforts to deploy 5G a few years ago. At this stage, 4G is still relevant because 5G networks and devices rely on 4G to enhance performance. 5G, the fifth generation of wireless technology, is the technological upgrade to the 4G networks that connect most current cell phones. 5G technology uses shorter, higherfrequency bands of the radio spectrum to deliver greater load capacity, faster speeds, lower latency (delay in transmission), and improved flexibility. The actual speed and range of 5G cellular signals varies according to where frequencies fall within the spectrum. Since 5G can run on any frequency of the airwaves, it allows telecommunications companies to deliver different 5G experiences to their customers. 5G can be implemented in low band—which uses a frequency range similar to 4G cellphones— or mid band or high band.
Being a relatively new technology, 5G continues to evolve with the development of networks and devices. As 5G got off the ground, the biggest limiting factor was device availability, according to Josh Lonn, vice president of wireless products at GCI. “Most networks launched without a customerready device to market, including GCI’s 5G network,” he says. “On the consumer side, we saw earlier support on the Android side, as we launched the S20 5G in mid-2020, followed by the 5G-capable iPhone 12 later that year. That device ecosystem has matured beautifully over the last couple of years, pushing 5G availability down to affordable levels for consumers. Our customers love those phones and know they are getting the best available service in Alaska.”
Applications and Implications
Many industries are just now pondering how they can best leverage 5G technology. Initial use cases involve “stranded” data where building a wired connection doesn’t make sense. Other applications include enhanced mobile workforce scenarios.
“5G for business is still early-days enough where it is tough to tease apart use cases that could just as effectively be served with a strong LTE [longterm evolution] network,” says Aaron Helmericks, senior director of energy and mining at GCI Business. “Over time, the buzzwords of today, like ‘network slicing’ and ‘ultra-reliable, low-latency communications’ will start to make more sense as the device ecosystem evolves and as the customer business cases sharpen. But, again, these services are an evolution over what we can already do—in some cases, on a more limited basis using LTE [which was the generation just before 4G].”
Helmericks says 5G isn’t as gamechanging for business in the way it has been for consumers. All that will change as the foundation grows stronger. “We’re in the third year of a ten-year curve,” he says. “Think of where LTE was in the third year of its evolution [circa 2012]: data rates were still what we’d consider to be in the yawner category today, and the industry was just starting to think about advanced LTE services like VoLTE [voice over LTE] and MIMO [multiple-input and multiple-output].”
VoLTE and MIMO are essential elements of wireless communication standards. VoLTE is an LTE high-speed wireless communication standard for mobile phones and data terminals, including internet of things (IoT) devices and wearables. And MIMO is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. 5G is still in the initial stage of development, Helmericks says. “That said, the next set of 5G enhancements coming down the roadmap will be focused on providing large enterprise businesses the next-generation wireless connectivity capabilities like enhanced security, network slicing, missioncritical, and edge compute,” he says.
AT&T describes 5G as the “most transformative wireless technology” yet, with huge potential to spark innovation in everything from transportation to entertainment. Businesses today need to think and operate differently—and 5G makes that possible, says Jason Inskeep, AVP of AT&T’s 5G Center of Excellence in Texas. “Compared to previous generations of wireless networks, 5G’s faster speeds and low latency are creating more opportunities for massive IoT and sensors connectivity, fueling innovation and digital transformation across all industries,” he says.
Although 5G requires upgraded cellular networks and devices capable of accessing the new networks, mobile providers are maintaining their 4G networks as they invest in 5G deployment. In addition, people who have 5G phones can expect them to work even where 5G service is limited because the 5G phones are backward compatible.
How does 5G compare to the 4G service most people use? The Federal Communications Commission indicates that some 5G services will provide data speeds up to 100 times faster and almost instantaneous response time. For example, it can take almost six minutes to download a feature-length movie with 4G. With 5G, the same movie can download as quickly as 15 seconds. Technically, current 4G speeds are approximately 12 to 36 megabytes per second (Mbps), while 5G services are expected to support speeds of up to 300 Mbps or greater.
Aside from mobile applications, some telecom providers are offering broadband wireless as an alternative to wired connections, such as digital subscriber line, fiber, or cable services.

AT&T’s 5G network reaches more than 281 million people and nearly 22,000 cities and towns in the country while its wireless network covers more than 99 percent of Americans (based on overall coverage in US licensed areas).
The company delivers three “flavors” of 5G—low band, mid band, and high band—to give customers individualized experiences, faster speeds, and greater capacity. In Alaska, AT&T offers lowband 5G, which can travel farther than its high-band 5G+ and penetrate buildings and objects. Its lower-frequency waves are slower for data, but it’s practically impervious to distortion.
AT&T’s mid-band 5G+ (using C-band spectrum) is faster and more responsive for the most demanding apps and services, from gaming to streaming to video conferencing. It travels farther than AT&T high-band 5G+ and provides faster speeds than the low-band version. And AT&T’s high-band 5G+ (using millimeter wave spectrum) delivers super-fast speeds but has limited reach. It’s more prone to distortion and is primarily employed in stadiums and high-traffic areas like entertainment venues.
According to Inskeep, companies large and small across all industries are transforming their business due to the impact of Industry 4.0, the oncoming (or ongoing) revolution involving massive IoT device proliferation and data intensive applications. “For example, AT&T is working with a company [whose name AT&T did not disclose] in Alaska to provide reliable and secure connectivity on the North Slope through a private wireless network,” Inskeep says. “Outdoor remote areas have dependency on connected devices, and WiFi can’t support all of the customer’s needs.”
AT&T’s 5G and private wireless networks serve the customer’s need. Inskeep explains, “With the private network, the company’s workers can access applications and IoT analytics and input information gathered in the field on their mobile devices, and the data stays private on the company’s local network. Before the installation of the private network, workers would have

to make handwritten notes about their equipment inspections. The private network also can support cameras to monitor gauges and other equipment remotely, reducing the amount of trips workers must take to remote facilities in treacherous terrains.”
5G from GCI
GCI launched Alaska’s first 1 Gbps and 2 Gbps internet service as well as the first standards-based 5G new radio (NR) service in the Anchorage Bowl in 2020. Recently GCI expanded its 5G footprint across the MatanuskaSusitna Borough. “Together, these areas cover over half of Alaska’s population,” Lonn says. “We will continue to push 5G service into our other urban markets, like Fairbanks, Juneau, and Kenai.”
As its next major undertaking, GCI is working on 5G service on the North Slope. In doing so, 5G will provide the area with wireless network connectivity to remote equipment, vehicles, inspection drones, mobile industrial IoT devices, and workers. GCI envisions improvements in productivity, efficiency, accuracy, and automation of intricate control processes at oil fields. “We’re excited to bring 5G to the North Slope in 2023, bringing state-of-the-art connectivity to our enterprise partners in that area,” Lonn says.
In addition to expanding coverage, GCI has focused on improving the speed of its 5G service. When the company launched Hometown 5G, it lit up five bands of radio spectrum. “Think of all that added spectrum as brandnew lanes on a superhighway,” Lonn says. “Even with the strong subscriber growth we’ve seen since our upgrade, those competitive speed test results show that there is still plenty of room to cruise.”
Currently, GCI delivers 5G to customers in all fifty states through a partnership with T-Mobile. The GCI 5G network in Alaska and the T-Mobile network that GCI customers have access to run on low band (600 MHz) spectrum. With GCI and T-Mobile’s low-band signal, information can still transmit at a rapid rate and travel through walls and buildings.
GCI says its 5G network provides bandwidth secure enough to support all unified communications and operational platforms for businesses, and the company sells a variety of 5G devices. These offerings from GCI allow consumers to leverage the latest 5G technology for their current and future needs. “Any customer that buys a 5G product or buys into Alaska’s most advanced network will be experiencing the best possible wireless connectivity in the state,” Lonn says. “Remember that where we are now is not how the 5G technology will perform in several years, and we haven’t even thought of the use cases that will revolutionize wireless connectivity.”
