Abstract
A system for monitoring the proximity and location of a child by a parent includes two transceiver units which communicate wirelessly. The child unit will transmit a signal to the parent unit so that the parent unit can determined the proximity of the child unit and its direction. A safe zone may be set by controls on the parent unit. When the child unit moves beyond the safe zone, the parent unit will generate an alert.
