  • Distributed architecture for a base station transceiver subsystem having a radio unit that is remotely programmable
    Patent number: 6801788
    Abstract: A telecommunication base station transceiver subsystem that can be easily configured to provide single or multi-carrier frequency service. 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. 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. Furthermore, the base station transceiver can be reprogrammed, reconfigured and/or statused by a network operations center.
