Abstract
Cellular communication systems (20) use repeaters (50) to communicate with subscriber units (24) otherwise shadowed from base stations (22). A networked repeater (50) is provided for use in a cellular communication system with low-earth orbit satellites (22) and mobile subscriber units (24). Networked repeater (50) includes a base transceiver module (54) for communicating with the base stations (22) and a plurality of subscriber transceiver modules (56), each of which communicates with subscriber units (24). The base transceiver module (54) is located so as to be unshadowed, i.e. able to have unimpeded communication with at least one of the satellites (22). The subscriber transceiver module (56) is located so as to provide unshadowed communication with the subscriber units (24) that would otherwise be shadowed, i.e. unable to have unimpeded communication with any of the satellites (22).
