A data communications system characterized by the combination of a base station connected to a plurality of repeaters for communicating with remote terminals in response to outgoing data from a host computer and for communicating with the host computer in response to incoming data from the remote terminals. Each repeater is assigned a coverage area with in a predetermined communications area to support data communications with the remote terminals located within its coverage area. In response to incoming data, a repeater conducts a signal amplification operation and outputs amplified incoming data to the base station via a first communications link. The base station processes the amplified incoming data and, in turn, generates processed incoming data for distribution to the host computer via a second communications link. The base station also processes the outgoing data from the host computer to generate processed outgoing data, and sends transmitted outgoing data to each repeater via the first communications link. Each repeater connected to the base station can amplify the transmitted outgoing data, and outputs amplified outgoing data to the remote terminals within its coverage area.
