Abstract
A method determines wireless radio locations in a network. The method includes identifying a group of location fixed radios in a network. Radios in the network with known location coordinates and/or known timing bias error values are grouped. RTT values are determined between each radio in the group and radios outside the group. Timing bias error values are determined for each radio outside the group. The timing bias error value for each radio outside the group of radios with known location coordinates and known timing bias error values is based on the determined RTT values. Location coordinates are estimated for each radio outside the group. A request is received for access to the network from a mobile radio device. The known location coordinates and estimated location coordinates of radios are used to determine a distance of the mobile radio device from one of the location fixed radios.
