WHAT IS CBRS?

Citizens Broadband Radio Service (CBRS) refers to 150 MHz of spectrum in the
3550 MHz to 3700 MHz range (3.5 GHz to 3.7 GHz) that the United States Federal
Communications Commission (FCC) has designated for sharing among three tiers of
users: incumbent users, priority access license (PAL) users and general
authorized access (GAA) users.

 

The incumbent tier is reserved for grandfathered users that had traditionally
used the 3550-3700 MHz range. This group mainly includes the Navy as well as
commercial fixed satellite stations. The CBRS band was designed taking into
consideration the geographical usage of the band as well as predictable data
that the incumbents had provided over time in order to limit interference for
the incumbents.



The PALs tier is for users that purchase spectrum licenses at the CBRS PALs
auction beginning in July 2020. The FCC will auction seven 10-MHz blocks in each
county in the United States. In total, the FCC is making 22,631 PAL licenses
available in its Auction 105. The licenses are for 10-year terms. The licenses
are purchased on a per-county basis, and bidders are limited to 40 MHz in any
county.

The General Authorized Access (GAA) tier is unlicensed spectrum that users can
access for free.

 


CBRS provides much needed mid-band spectrum for a variety of users, including
wireless carriers, cable operators, and organizations.

Report on CBRS

Wireless carriers are expected to use CBRS to enhance their networks with
mid-band spectrum, especially in dense urban areas. Cable operators that deliver
mobile virtual network operator (MVNO) services can use CBRS to offload some
traffic from their wholesale wireless providers, saving on wholesale costs. Both
wireless carriers and cable companies could use CBRS to deliver fixed wireless
access (FWA) services. And enterprises will be able to use the spectrum to
potentially build their own 4G or 5G private wireless networks. In addition,
CBRS is also expected to outperform Wi-Fi for in-building use.

CBRS is also unique because it includes a spectrum sharing aspect. A group of
Spectrum Access System (SAS) managers have been designated to manage the use
and sharing of the spectrum. Those SAS managers include Federated Wireless,
Google, CommScope, Sony and Amdocs.

When a user wants to use the CBRS band, he puts in a request via the SAS
cloud-based system. If the spectrum is free in the desired geographic location,
the SAS will grant the request. In order to access the CBRS spectrum, users will
need to use Citizens Broadband Radio Services Devices (CBSDs) that must be
registered with the SAS.
