Claim:
1. A method comprising: receiving, by a computing device, known location information for a first access node, the known location information corresponding to a network associated with the first access node; determining, based on the known location information, a first value of a first timing offset for the first access node, wherein the first value of the first timing offset is based at least on an expected time for a signal to reach the first access node via a transmission line of the network; determining a second value of the first timing offset; determining a difference between the first value and the second value; translating the difference to a known distance using a velocity of propagation in a transmission media; responsive to the difference satisfying a first threshold associated with an expected timing offset, determining, by the computing device, that the known location information was inaccurate and determining a second timing offset for a second access node located within a predetermined distance of the first access node; determining a level of inaccuracy of one or more of the first timing offset or the second timing offset; and responsive to whether the level of inaccuracy satisfies a second threshold associated with a discrepancy in a set of data used to determine the known location of the first access node, including known location, coverage map or timing offset information, performing a statistical analysis to determine which of the set of data are inaccurate, and based on the determination and a collection of wireless Received Signal Strength (RSSI) information from a plurality of user devices connected to the first access node, confirming the accuracy of the known location information for the first access node or adjust the known location information for the first access node.
