<p>The method involves estimating flight time between initiating and requesting radio equipments (A, Z) corresponding to a duration of transmitting signals between the equipments along a strong propagation path (t2). A channel sonding frame is sent to the equipment (Z) by the equipment (A), and a flight time difference between the path and another path is estimated from the received signals by the equipment (Z). Another flight time is determined by subtracting the former flight time from the estimated difference, and distance between the equipments is calculated from the latter flight time. Independent claims are also included for the following: (1) a method for locating an equipment (2) an estimation device integrated in an initiating radio equipment (3) an estimation device integrated in a requesting radio equipment (4) a computer program comprising code instructions for controlling operations carried out by an initiating radio equipment (5) a computer program comprising code instructions for controlling operations carried out by a requesting radio equipment.</p> |
