ABSTRACT:
A method for use in a wireless communication system with a network overlay geolocation system having a sparse deployment network in which base stations of the wireless communication system may or may not have a co-located wireless location sensor (WLS). The method uses U-TDOA measurements on the uplink (reverse) signal and E-OTD measurements on the downlink (forward) signals to estimate a location for a mobile appliance.
