Abstract:
Techniques are provided which may be implemented using various methods and/or apparatuses to determine time difference of arrival of signals from two base stations as received at a mobile device, to use the time difference of arrival to determine differential forward link calibration for at least two base stations, and also to determine location using the differential forward link calibration for at least two base stations, determined using the time difference of arrival of signals from at least two base stations as received by a mobile device.
