Disclosed is a base station comprising an antenna and a plurality of
integrated transceiver modules. Each integrated transceiver module
includes a radio and a decentral duplexer connected to the radio and the
antenna for transmission of and reception of communication signals. The
integrated transceiver module therefore modularizes the base station so
that all of the components of a base station can be located on a single
module (e.g., one printed circuit board (PCB)). The base station can be
upgraded by inserting additional integrated transceiver modules into the
base station.
