Abstract
Improved distance estimation of a selected transmitter. An improved distance estimate from a target transmitter to a receiver is produced by assessing the target transmitter to determine transmit power, and combining this information with a propagation model, received signal strength, and reference signal strength indications. Target transmit power may be assessed through knowledge of the target device or device class, and/or transmit power reporting features of target wireless networks. The assessment may be made through looking up reported target device characteristics in a database, making inferences based on target device characteristics, or through standards-based diagnostic and/or reporting mechanisms.
