Abstract

A repeater (100) that extends the range of a wireless communication system (120) especially one using Time Division Duplex (TDD) protocols. The device preferably translates signals (120) received on a first radio frequency channel to a second radio frequency channel. The repeater preferably monitors one or more channels for transmissions. When a transmission on one channel is detected, the repeater is configured to translate the received signal to another channel where it is then transmitted. The device thus solves a problem of isolating input and output signal from one another.
