Citizens Broadband Radio Service (CBRS)
In the U.S., the 3.55 – 3.70 GHz band (3550 – 3700 MHz) has evolved into a high-value shared spectrum asset for broadband and private wireless deployments.
The regulatory framework now allows innovative wireless services previously unavailable, enabling commercial users to deploy reliable mid-band networks at scale.

The regulatory framework now allows innovative wireless services previously unavailable, enabling commercial users to deploy reliable mid-band networks at scale.
Spectrum Allocation Server (SAS)
Access to the CBRS band is managed through certified Spectrum Access Systems (SAS). Once a CBRS-capable base station (CBSD) is installed, it contacts the SAS to request available channels, receives authorization, and commences operation—all while ensuring federal users and incumbent systems remain protected from interference
Shared-Spectrum Prioritisation Framework
The CBRS band is split into a three-tiered spectrum prioritization framework to accommodate a variety of commercial uses while sharing with incumbent federal and non-federal users of the band.
- Incumbent Access: Federal users (e.g., DoD, military radar, satellite ground-stations, certain utility operations) retain highest priority and interference protection.
- Priority Access: Licensed users holding Priority Access Licences (PALs) in defined geographic areas (census tracts) enjoy prioritized use of the 3.55–3.65 GHz portion with predictable performance.
- General Authorized Access: The final priority goes to GAA users of the spectrum. This level will allow the widest possible group of potential users. GAA users are permitted to use, through dynamic allocation, any portion of the 3550-3700 MHz band not assigned to a higher tier user. They will also be able to operate in unused portions of the Priority Access channels.
Any certified user can operate on a dynamic, opportunistic basis in portions of the band not occupied by higher-tier users, ideal for private LTE/5G, enterprise and fixed wireless access (FWA) networks.
