Abstract

An arrangement is disclosed for improving the signal to noise ratio on the reverse path of a GSM wireless communications system that utilizes an existing broadband distribution network to carry communication signals between wireless telephones and remote transceivers to centrally located transceivers and the telephone network. The signal to noise ratio is improved by a time slot muting arrangement in the remote transceivers that senses when there is no communication signal coming from a wireless telephone for a predetermined period and provides squelching in the remote transceiver during any time slot in which a wireless telephone is not operating to thereby reduce white noise applied to the broadband distribution network.
