Abstract
In a conventional Time Division Multiple Access (TDMA) wireless system, the specified distance between a mobile unit and the base transceiver system (BTS) cannot exceed predetermined distances because of time slot synchronization constraints. In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band translators include a loop back circuit that permits a host BTS to measure the propagation time delay by sending test access signals between the host BTS and each in-band translator. The measurements are then used to adjust a time delay in an uplink signal as received from each in-band translator by the BTS in normal operation.
