Patent ID: 7734298

Claim:
A method comprising: (1) receiving (i) a first measured pathloss for a signal that is processed by a wireless terminal at a first time T 1 and (ii) a second measured pathloss for the signal at a second time T 2 , wherein the first time does not equal the second time; (2) estimating a first location of the wireless terminal at the second time based on (i) the first measured pathloss, (ii) the second measured pathloss, and (iii) an estimate of the probability that the wireless terminal at a second location at the first time T 1 will still be at the second location at the second time T 2 ; wherein (2) comprises: (2.1) comparing the first measured pathloss to: (i) a first expected pathloss of the signal when the wireless terminal is at a third location at the first time T 1 , and (ii) a second expected pathloss of the signal when the wireless terminal is at a fourth location at the first time T 1 ; and (2.2) comparing the second measured pathloss to: (i) a first expected pathloss of the signal when the wireless terminal is at a fifth location at the second time T 2 , and (ii) a second expected pathloss of the signal when the wireless terminal is at a sixth location at the second time T 2 .
