Abstract:
Distributed antenna systems provide location information for client devices communicating with remote antenna units. The location information can be used to determine the location of the client devices relative to the remote antenna unit(s) with which the client devices are communicating. A location processing unit (LPU) includes a control system configured to receive uplink radio frequency (RF) signals communicated by client devices and determines the signal strengths of the uplink RF signals. The control system also determines which antenna unit is receiving uplink RF signals from the device having the greatest signal strength.

Claim (Index 1):
A wireless communication system wireless communication system, comprising:\n at least one downlink interface configured to:\n receive downlink radio frequency (RF) signals; and \n distribute the downlink RF signals over at least one optical communications medium to a plurality of remote units; \n at least one uplink interface configured to:\n receive uplink RF signals from the plurality of remote units over the at least one optical communications medium; and \n distribute the received uplink RF signals; \n the plurality of remote units optically coupled to the at least one optical communications medium, and each remote unit comprising at least two antennas configured in a diversity arrangement, the plurality of remote units configured to use a multiple input/multiple output (MIMO) scheme and to be installed in known locations, the a plurality of remote units configured to:\n receive the downlink RF signals as optical downlink RF signals; \n convert the optical downlink RF signals into electrical downlink signals; \n transmit the downlink RF signals into a respective coverage area; \n receive uplink RF signals from client devices located in respective coverage areas; and \n distribute the received uplink RF signals; and \n a location processing unit (LPU), comprising:\n a plurality of signal monitoring devices configured to receive each of the uplink RF signals distributed from the plurality of remote units located in the known locations; and \n a controller configured to:\n determine signal strengths of the received uplink RF signals; \n determine which remote unit among the plurality of remote units is receiving the uplink RF signals from at least one client device having the greater signal strength; and \n determine location information for the at least one client device based on identification of the remote unit receiving the uplink RF signals having the greater signal strength.
