Patent ID: 8879607

Claim:
A method comprising: storing a constant path loss exponent corresponding to free space; receiving a signal via a rake receiver of a user device; identifying a maximum received signal strength, during an instant t, based on a signal strength associated with the signal relative to fingers of the rake receiver; storing a current maximum received signal strength value based on the identifying; determining whether the current maximum received signal strength value is a first time stamped maximum of maximum received signal strength values that are stored corresponding to a sequence of samples of signal strengths received; calculating a current indoor position of the user device based on the constant path loss exponent and the current maximum received signal strength value when a determination is that the current maximum received signal strength value is the first time stamped maximum of maximum received signal strength values, wherein the constant path loss exponent is used regardless of a type of multipath environment in which the user device resides; and outputting the current indoor position.
