Rf repeater for tdma mobile telephone systems

Abstract

An RF repeater for exchanging time division multiple access (TDMA) transmit and receive signals between a mobile handset and a CATV plant or other signal conduit has a signal timing detector responsive to the timing of transmit signals being broadcast to the handset to provide timing information indicative of the timing of receive signals being received from the handset. A signal level detector responsive to the signal level of the receive signals provides signal level information. A signal control device responsive to the timing information and the signal level information provides a signal level control output for time slotted control of the receive signals. The timing and signal level information may be used to effect diversity selection between receive signals from two spaced antennas at the repeater and/or diversity selection may be effected between two versions of the receive signal at a base station after passing through the signal conduit.
