Citizens Broadband Radio Service Device (CBSD) are stations that can run the Citizen Band Radio Service (CBRS) over the Spectrum Access System (SAS), either by means of Priority Access Licenses (PAL) or General Authorized Access (GAA). For CBSD stations consisting of multiple nodes, each node must communicate with the Spectrum Access System (SAS) over a single network interface
. The individual nodes are defined by a system-wide unique CBSD ID. In addition, group identification from a CBSD group is possible.
