Abstract
A digital cellular radio communication system having a remote repeater is provided. The communication system includes a central communication site which: transmits and receives signals in a first radio channel assigned according to a cellular communication system channel reuse plan, transmits signals to and receives signals from a cellular communication network unit, and digitally processes received signals for subsequent transmission in the first radio channel or to the cellular communication network unit. The communication system further includes a remote communication site, substantially remotely located from the central communication site, which: receives a signal in either the first radio channel or a second radio channel assigned according to the cellular communication system channel reuse plan, channel shifts the received signal between the first and the second radio channels, and transmits the shifted signal in the other of the first and the second radio channels.
