Abstract
A method of personal location monitoring in a wireless communication system operating on a local area network. The method includes initializing a master communication device and a slave monitor device on the local area network. A next step transmitting a signal on the local area network by the slave monitor device. A next step includes the communication device receiving the signal on the local area network and measuring the signal strength which is compared to a threshold. A next step includes triggering an alarm in the communication device when the signal strength falls below the threshold, indicating that the monitor device is straying from the proximity of the local area network.
