What Citizens Broadband Radio Service Means for America
Government mobility is about to get a massive upgrade. That’s because in late 2018, the Federal Communications Commission (FCC) finalized rules for unlocking the 3.5GHz band of spectrum known as the Citizens Broadband Radio Service (or CBRS).
Government Business Council (GBC), the research arm of Government Executive Media Group, has partnered with Ruckus Networks to create an immersive infographic detailing what CBRS is all about and what it means for the federal government in 2019 and beyond.
What is Citizens Broadband Radio Service?
Hover over the radio wavelengths below to understand their use.
Also called the ‘innovation band’, the 150 MHz of wireless spectrum is now completely dedicated toward CBRS use.
For years, spectrum has provided government, particularly the Department of Defense (DoD), with the wireless support it needs to manage and safeguard satellite, radar, and military communications.
Spectrum is already a scarce resource that citizens and government alike depend on for their daily wireless needs.
CBRS marks an evolutionary milestone to the framework of shared spectrum: by deploying a three-tier model, it allows for spectrum sharing, allowing general authorized users to deploy private LTE based solutions of their own.
The three-tier model protects incumbent users in the band, such as satellite, radar, and other priority operators. The FCC is expected to authorize complete commercial CBRS spectrum availability in Q3 2019. Essentially, if the higher tiers aren’t using all of the spectrum in a given time, general authorized access users are free to use that spectrum.
Indeed, CBRS is a perfect vehicle for unleashing the power of private wireless LTE. Compared to WiFi, LTE networks offer greater bandwidth capacity, lower latency, more predictability, and improved security with built-in over-the-air encryption.
What is the three-tier model for CBRS?
Tier One: Incumbents
Incumbent Access users include authorized federal users, grandfathered Fixed Satellite Service earth stations, and, for a limited time, Grandfathered Wireless Broadband Licensees in the 3650-3700 MHz portion of the band. These users will be protected from harmful interference from Priority Access and General Authorized Access (GAA) users.
Tier Two: Priority Access
The Priority Access tier consists of Priority Access Licenses (PALs) that will be assigned using competitive bidding within the 3550-3650 MHz portion of the band. Each PAL is defined as a renewable authorization to use a ten megahertz channel within a county for ten years. Up to seven total PALs may be assigned in any given county with up to four PALs going to any single applicant.
Tier 3: General Authorized Access
The GAA tier is licensed-by-rule to permit open, flexible access to the band for the widest possible group of potential users. GAA users are guaranteed access to a minimum of 80MHz and are permitted to use any portion of the 3.5 GHz band not assigned to a higher tier user and may also operate opportunistically on unused Priority Access channels.
Why Expand CBRS to Federal Agencies?
The federal government’s data needs have reached a tipping point, all but ensuring that CBRS will be the top mobile priority in 2019. A GBC survey of federal employees in late 2018 shows unprecedented appetite for mobility and wireless fidelity:
use one or more wireless mobile devices to carry out their work duties
said their work-issued mobile devices were essential for using on the job
said their ability to be productive is considerably or extremely dependent on wireless access
said they had no familiarity or knowledge of CBRS prior to taking the survey
The government’s wireless usage is only going to increase as the number of mobile devices and network-connected touchpoints expand in scale and volume. Traditional WiFi can’t accommodate these trends by itself, and providing coverage via existing wireless models can’t guarantee secure, uninterrupted service when users require it.
Under CBRS, government agencies will be able to deploy their own private wireless networks in mere hours, providing ‘campus connectivity’ to an increasingly mobile workforce. CBRS will in the future make innovative use of a neutral host, in which a shared LTE deployment can serve subscribers from multiple operators, thereby providing more indoor coverage and data capacity.
Wireless providers tout the benefits of WiFi and private LTE, but one area where LTE clearly outshines WiFi is in mobility. Whereas WiFi users are confined to operating in a specific range from a router, LTE provides mobility wherever the user’s device is authorized to operate. That’s a huge asset for government employees whose work depends on having a stable connection across multiple mission centers.
The U.S. government may be the world’s largest target of cybersecurity attacks. In 2017 alone, federal agencies reported more than 35,000 cyber ‘incidents’ to the Homeland Security department! CBRS offers improved security over traditional WiFi. As GBC’s survey of federal employees showed, 1 in 2 respondents admitted to using a cellular data connection at work to access information when WiFi was down.
What does this look like in action?
Intelligence agencies like the CIA, NSA, and NGA could provision LTE network access that is completely secure and contained to their agency without having to relay data back through mobile carriers and thirty party providers.
Working with CBRS providers, agencies such as Department of Transportation and Homeland Security could equip their vehicles with LTE gateways, providing a level of mobility not available via traditional WiFi.
Unleash the Internet of Things
CBRS lets agencies truly own their IoT device management. Imagine DoD military outposts augmenting their networks with surveillance devices for round-the-clock visibility, or Department of Energy personnel receiving real-time feeds of electrical grid infrastructure that magnify changes in the system.
By harnessing LTE access through CBRS, General Services Administration could help agencies procure Push-to-Talk phones or mobile devices specifically tailored to that agency’s mission needs, ensuring total privacy of communications.
