CBRS stands for Citizens Broadband Radio Service. It is a set of frequencies in the 3.5 GHz band that has been set aside by the Federal Communications Commission (FCC) for shared use by different types of users, including commercial, industrial, and government entities. These frequencies are available for use on a shared basis, allowing for the deployment of wireless networks in areas where traditional licensed spectrum may not be available or may be too expensive.
CBRS operates in the 3.5 GHz band, which is a mid-band frequency that offers a balance of coverage and capacity. The CBRS band is divided into three categories, known as Priority Access Licenses (PALs), General Authorized Access (GAA), and Incumbent Access. PALs are licensed on a long-term basis and are intended for commercial use. GAA is unlicensed access and is intended for general use and Incumbent Access is intended to protect existing users in the band such as federal radar sites.
The CBRS band is particularly well-suited for dense urban areas, where the demand for wireless services is high and the availability of spectrum is limited. It can also be used for a variety of applications such as, home and enterprise wireless networks, IoT and M2M and in-building wireless.
