ABSTRACT:
In one embodiment the present invention includes an arrangement for monitoring RF signals for use in a base station, said arrangement comprising a demodulation circuit operable to demodulate RF signals, an RF signal transceiver, and a controller. The RF signal transceiver is operable to transmit downlink RF signals to a wireless terminal and receive uplink RF signals from the wireless terminal. The RF transceiver further comprises: an antenna operable to receive first RF signals within a first frequency band and second RF signals within a second frequency band; a signal router connected to the antenna and having first and second ports, said signal router operable to provide signals within the first frequency band to the first port and signals within the second frequency band to the second port; a first RF switch connected to the first port; a first RF signal path connected to the first RF switch; a second RF signal path connected to the second port, and a second RF switch connected to the first RF signal path and the second RF signal path, said second RF switch having an output for connection to the demodulation circuit. The controller is operably connected to the first RF switch, the second RF switch, and the demodulation circuit. The controller causes the first RF switch to connect the first signal path to the first signal port and further causes the second RF switch to connect the first RF signal path to the demodulation circuit to facilitate monitoring of the first RF signals, and wherein the controller causes the second RF switch to connect the second signal path to the demodulation circuit to facilitate monitoring of the second RF signals.
