Patent ID: 8730848

Claim:
A time-division duplex (TDD) repeater system for transmitting communication signals in a wireless network comprising: a master unit configured for communicating with a base station of the wireless network; at least one remote unit configured for communicating with a network terminal and located away from the master unit; a waveguide connecting the remote unit with the master unit for transmitting the communication signals in an uplink direction from the remote unit to the master unit and in a downlink direction from the master unit to the remote unit; both the master unit and the remote unit including a switch for changing direction between the signal transmission in the uplink direction and the signal transmission in the downlink direction; and the master unit including a synchronizing unit configured for receiving a portion of the communication signals that are to be transmitted in the repeater system and for determining a clock pulsing signal from the communication signals fed to the master unit, the synchronizing unit further configured for using the clock pulsing signal and for generating and supplying a control signal corresponding to this clock pulsing signal to the switches of both the master unit and at least one remote unit for selecting the direction of the signal transmission, the control signal providing a change in the direction of the switches of the master unit and at least one remote unit with a time staggering of a duration corresponding approximately to a signal propagation time between the master unit and the remote unit; the synchronizing unit further configured for transmitting the control signal for selecting the direction of the switch in the remote unit, together with the communication signals, at different frequencies, through the same waveguide to the remote unit.
