SAS
Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band of the 3.5 GHz band (3550 MHz to
3700 MHz) in the United States.
FCC has authorized the full use of the CBRS band for wireless service provider commercialization under a three-
tiered spectrum authorization framework to accommodate a variety of commercial uses on a shared basis with
incumbent federal and non-federal users. With this service, wireless carriers using CBRS are able to deploy 5G
mobile networks without having to acquire spectrum licenses.
When devices such as your CFW-2172 want to use the CBRS band they put in a request to a cloud-based
Spectrum Access System (SAS) to reserve unused General Authorized Access channels in a particular geographic
area. If channels are free, SAS can grant the requests.
When devices with permission to use channels no longer require access, their unused authorization is put back
into the pool that the SAS draws from to grant requests to other users with minimal interference.
