Abstract: An RF repeater arrangement for exchanging transmit and receive signals between a handset and a base station in a wireless telephone system automatically compensates for attenuation losses. The RF repeater arrangement includes first and second RF repeater parts connected by a signal conduit, the first part interfacing with the base station and having a signal level detector for detecting the level of the transmit signal, a microprocessor controller for quantizing and encoding the signal level detected by the level detector and a modulator for modulating the signal level data and outputting the modulated signal level data to the signal conduit.

Abstract: A method of controlling the switching of components of a cordless telephone system includes sensing the signal link quality of the signals received from a handset at a basestation through signal exchanging components. e.g. RADs, supplying switching control signals to the signal exchanging components so as to cause adjacent ones of the signal exchanging components to have mutually different switched states; and changing the control signals so as to reverse the switched states of the signal exchanging components in response to a predetermined deterioration of the signal link quality.

Abstract: An RF repeater for interfacing with a base station for exchanging transmit and receive signals in a time division duplex cordless telephone system comprises a multicarrier amplifier having an input and an output and a transfer switch connected to the amplifier output and the amplifier input and having first and second switch states. The switch means connects receive signals from the handset to the amplifier input and the amplifier output to the base station in the first switch state, and connects the base station to the amplifier input and transmit signals from the amplifier output to be broadcast to the handset in the second switch state. The operation of the switch is controlled so that the transmit and receive signals are alternately amplified by the amplifier. Thus, only a single amplifier is required.

Abstract: An RF repeater arrangement for use in linking cordless handsets to a base station, has RF repeaters spaced from a common power supply unit and so distributed over an area to be serviced by the power supply unit that each of the RF repeaters is spaced from at least one other of the RF repeaters by a distance which is less than the range of coverage of the handsets. The power supply unit has a DC power supply connected to supply DC power to said a cable inner conductor, and RF repeaters each have an antenna for exchanging the radio signals with the handsets, transmit and receive circuits and a DC power pick-up connected to the co-axial cable inner conductor for powering the respective RF repeater.
