Methods and apparatuses are presented for obfuscating the locations of terrestrial wireless transceivers, including wireless access points and femtocells. According to some embodiments, a method may receive, by a mobile device, data for a terrestrial wireless transceiver, wherein the data includes location coordinates of the terrestrial wireless transceiver, and wherein the location coordinates include an error term. Additionally, the method may include determining the error term based on the data. Furthermore, the method may include determining a corrected location of the terrestrial wireless transceiver by removing the error term from the location coordinates. In some instances, the data can further include a unique identifier associated with the terrestrial wireless transceiver, and wherein the error term is further determined based on the unique identifier.
