What is CBRS?
Citizens Broadband Radio Service
In 2015, the FCC (Federal Communications Commission) adopted rules for shared commercial use of the 3550-3700 MHz band (3.5 GHz band). The Commission established the CBRS (Citizens Broadband Radio Service) and created a three-tiered access and authorization framework to accommodate shared federal and non-federal use of the band. Rules governing the Citizens Broadband Radio Service are found in Part 96 of the Commission’s rules.
*Unprotected means that if the network is congested
Tier 1 and 2 transaction have priority.
This has nothing to due with network security.
