Abstract

A repeater (1) particularly suitable for a time-division duplex transmission of communication signals is provided. The repeater (1) comprises a master unit (2) for communicating with a base station (3) of a wireless network, at least one remote unit (4) for communicating with a network terminal, as well as a waveguide (11) connecting the remote unit (4) with the master unit (2) for transmitting the communication signals in an uplink direction (6) from the remote unit (4) to the master unit (2) and in a downlink direction (5) from the master unit (2) to the remote unit (4). Both the master unit (2) and the remote unit (4) comprise one switch (19, 20) each for changing over the signal transmission between uplink direction (6) and downlink direction (5). Both switches (19, 20) are selected by a synchronizing unit (21) arranged in the master unit (2), the synchronizing unit (21) being designed for determining a clock pulsing from the communication signal fed to the master unit (2)—in particular from the base station (3)—and for supplying a control signal corresponding to this clock pulsing to the switches (19, 20).
