ABSTRACT:
A repeater system combines co-located antennas, limited and controlled downlink signal amplification, stability management and an amplification indicator to create a user-installed solution to co-channel interference within cellular systems, in strong signal environments such as elevated locations or high-rise building. The invention may be particularly relevant to cellular systems, such as CDMA, that allow limited imbalance between uplink and downlink path losses, thus enabling the design of an inexpensive downlink repeater which creates moderate signal amplification for selected line-of-sight signals, defeating co-channel interference over a small area. Signal amplification is maintained at a level below the capacity of the system to support imbalance, guaranteeing reliable cellular calls.
