Abstract
A system and method for preventing relay attack on a passive entry system (PES) or other passive system (PS) included within a vehicle or other entity. The relay attack prevention may be based in part on an assessment of whether the fob is able to distinguish signal strength relative to messages communicated form different antennas within the vehicle and/or amongst different signal amplitude communicated from the same antenna.
