Abstract
A system and method of locating a key fob with respect to a vehicle includes: detecting short-range wireless signals communicated between the key fob and a plurality of nodes at the vehicle using an IEEE 802.11 protocol; calculating the distance of the key fob relative to each of the nodes attached to the vehicle based on the detected short-range wireless signal; and determining the location of the key fob based on the distance of the key fob relative to each of the nodes.
