Method of localization

A method for localizing terminals is carried out by preparing a plurality of antennas at distinct points of an area to be monitored and acquiring by means of said antennas an identification signal uniquely associated with a terminal present within the area to be monitored. For each antenna, a measurement is made of a received strength signal, RSS, representative of a strength of the identification signal acquired by the antennas and a probability distribution of a position of the terminal with respect to each antenna is generated as a function of the respective RSS. The position of the terminal is determined by maximizing the probability distribution.
