  • Multi-repeater communication system
    Patent number: 6032020
    Abstract: A structure (24) includes a plurality of repeaters (34), each having a primary transceiver (36) and a secondary transceiver (38) electromagnetically located upon a clear side (30) and a blocked side (32), respectively, of a barrier (26). Each primary transceiver (36) and secondary transceiver (38) communicate using an intra-repeater signal (46). Each intra-repeater signal (46) is output from its respective primary transceiver (36), combined with other intra-repeater signals (46) by a combiner (50), passed over a communication infrastructure (22), separated from other intra-repeater signals (46) by a separator (54), and input to its respective secondary transceiver (38). Optionally, each intra-repeater signal (46) may be retrieved from the communication infrastructure (22), separated from other intra-repeater signals (46) by a separator (62), amplified by a bandpass amplifier (64), combined with other intra-repeater signals (46) by a combiner (66), and inserted back into the communication infrastructure (22).
