Abstract
A distance estimation system is disclosed for estimating a distance between two electronic devices. The system includes a power adjustable transmitter that is capable of having its power level adjusted between successive transmissions of packets of data, a remote device that is remote from the power adjustable transmitter for receiving the packets of data, and a distance estimation unit. The distance estimation unit is for generating a distance estimation signal responsive to the packets of data received at the remote device such that the distance estimation signal is associated with a power level at which the power level adjustable transmitter is not able to sufficiently transmit the packets of data to the remote device.
