RADIO COMMUNICATIONS SIGNAL BOOSTER

摘要

23159-1506 An apparatus for extending coverage of a fixed radio transmitter-receiver to selected mobile transceivers in a predetermined graphical area is described. The apparatus includes a number of signal repeaters spaced throughout at least part of the geographical area such that at least one of the repeaters is in radio communication with the transmitterreceiver and a second of the repeaters is in radio communication with the first repeater. The second repeater senses a signal from a mobile transceiver and retransmits that signal to the first repeater. The first repeater senses that signal and retransmits it to the fixed transmitter-receiver. The apparatus is capable of repeating a limited number of channels without generating spurious signals.
