  • Patent number: 7450967
    Abstract: In a combination of a transceiver cabinet housing a plurality of transceivers and one or more DECON boards for supporting said transceivers, and a cable for connecting one or more of said transceivers through a selected DECON board to selected control and radio interfaces, a first end of the cable is connected to the selected DECON board, and the second end of the cable is split into and includes multiple discrete portions, each discrete portion being associated with one particular transceiver supported by the selected DECON board such that each discrete portion, and thus one particular transceiver, can be connected to a particular RTT board of a control and radio interfaces.

  • Patent number: 7190973
    Abstract: A method is disclosed for adapting base station equipment at a sectorized cell site to relieve high call blocking rates in a first heavily utilized sector. The method includes selecting a TCB cabinet corresponding to a second more sparsely utilized sector and placing first sector transceivers in a first set of designated slots of the TCB cabinet and second sector. A split receive (uplink) signal path within the second sector TCB cabinet is achieved by substituting a four input port combiner card for a conventional two input port combiner card. First and second sector receive signals are respectively directed to first and second input port pairs of the combiner card and are separately routed by the TCB cabinet backplane circuitry to the first and second sector transceivers. The foregoing method allows the cell site owner to add needed transceivers to the heavily-utilized sector without purchasing and installing a new base station.
