Abstract

A telecommunication base station transceiver subsystem that can be easily configured to provide single or multi-carrier frequency service. Capacity is increased and diversity reception is maintained from a single to a dual frequency system without the need for additional antennas. The base station is divided into a main unit and a radio unit such that the radio unit is positioned proximate to the antennas and the main unit is remotely located from the radio unit. Furthermore, a single base station transceiver can provide service via multiple wireless protocols, such as CDMA, TDMA, GSM or Analog. The base station transceiver can also operate on various transmit/receive frequencies as well as variable transmit power settings.
