A system and method of locating a key are disclosed. The key is configured to communicate with a base station through a plurality of antennas that are coupled to the base station. The method includes turning off each of the plurality of antennas, turning on one of the plurality of antennas, measuring a first received signal strength, turning off the one of the plurality of antennas and measuring a second received signal strength. The key is determined to be located within a predefined area if the difference between the first received signal strength and the second received signal strength is above a preset threshold.

Field measurement compensation

A wireless charging system is disclosed. The wireless charging system includes a coil to create electromagnetic field and a sniffer system to detect a presence of a low frequency (LF) signal. The sniffer system is configured to deactivate the coil for a predetermined duration and perform an operation to detect the presence of the LF signal.
