1.1.2. Base Station Components
Each base station site contains several components that enable:
• Connection to telecom system
• Internal switching of traffic
• Power supply
• Radio communications.
Some of these components are mandatory and others optional depending on the
configuration of the site and the particular type of network backbone
interconnection.
Each Base Station Radio (BSR) is optionally physically connected to a Base Station
Distribution Unit (BSDU), which provides data connectivity, power, and local
switching functionality, as well synchronization between the BSRs. A BSDU can
serve up to six BSRs, and up to four BSDUs can be chained in a single base station
to support up to 24 BSRs.
