A method for fixing a location of a fixed wireless terminal. The method includes receiving a first plurality of telecommunication signals at the fixed wireless terminal, generating a first model of a network environment of the fixed wireless terminal based on an identification code sent with each of the first plurality of received signals, wherein the identification code is indicative of a base station from which the signal was transmitted, and the signal strength of each of the first plurality of received signals, receiving a second plurality of telecommunication signals at the fixed wireless terminal, generating a second model of the network environment of the fixed wireless terminal based on an identification code sent with each of the second plurality of received signals, wherein the identification code is indicative of a base station from which the signal was transmitted, and the signal strength of each of the second plurality of received signals, and determining whether the first and second models differ beyond a predetermined limit.
