Abstract: A communications system has a base center with radio transceivers for providing a number of radio frequency (RF) communications links and a plurality of fixed radio ports through which RF signals can be transmitted and received over the air. A fiber optic network interconnects the RF transceivers and the fixed radio ports and carries the RF signals by means of optical signals. There is a plurality of radio/optical interfaces by which RF signals can be modulated onto and demodulated from one or more optical signals, between the RF transceivers and the fiber optic network, and between the fiber optic network and the fixed radio ports. A matrix switch selectively interconnects the transceivers and the radio ports through the fiber optic network.
