Abstract
A wireless distribution system includes a number of remote units distributed in a coverage area to receive wireless signals and to provide the signals through the distribution system to input ports of an expansion unit where the signals are combined, detectors operatively connected to one or more of the plurality of input ports to determine the presence of information carrying signals at the input ports, a number of selection circuits to select signals in which information has been detected, and a node to combine the selected signals.
Claims17
