Abstract

An object of the present invention is to provide a method of proximity detection based on transmitting at random intervals burst of an RF signal and receiving, while not transmitting, a received RF signal. When detecting said received RF signal emitted by a target in range, an alarm signal is provided to warn of the proximity of the target. Another aspect of the invention is to deploy the above method among members of a territory and provide a monitoring patrol to verify if the proximity of those members can be detected from their RF signal. Another aspect of the invention is to provide to those members a plurality of statuses among which each member selects one corresponding to its current status and transmits that status in the RF signal he transmits, thereby informing other members in range of his current status.
