Abstract
Methods and apparatus are provided for estimating a location of a plurality of wireless terminals. Signal strength measurements are obtained for at least one packet transmitted by each of the wireless terminals; and a Bayesian algorithm is applied to the signal strength measurements to estimate the location of each wireless terminal. In an infrastructure-based deployment, signal strength measurements are obtained from one or more signal monitors. In a client-based model, signal strength measurements are obtained from a client associated with a respective wireless terminal.
