Abstract: A functional module is provided for connection in a modular transceiver system in a radio communication network. The functional module has an input for receiving input signals at an RF frequency, an RF signal processor for receiving and processing the input signals, an ID generating circuit for generating an ID signal which characterises the functional module, and an ID port for transmitting the ID signal to an interrogation circuit. A self-configuring transceiver module for receiving and acting on the ID signal is also provided.

Abstract: Power control of output RF signals in a mobile radio communication network is described. A base transceiver has a booster module (12) attached for increasing the power of the output RF signals. A power levelling loop controls the transmission power of the unboosted transceiver. When a booster module (12) is attached, the loop is extendible to control the power of the boosted RF signal output from the booster module. A node (52, 53) connects the amplifier circuit (4) of the transceiver and booster module (12). The node allows an RF signal to be supplied from the amplifier circuit (4) to the booster module (12) for transmission. The node (52, 53) also forms part of the extended power control loop and allows the detected level of the boosted signal to be returned to the transceiver.
