Abstract
A method and range monitoring system for verifying that communication between two communicating units is of satisfactory quality and that the units are within a predetermined range from one another, wherein the units are in non-continuous communication. One or both units test that the quality and distance by sending a signal to the other unit, and expecting a response signal. If no response signal is received, an alert is fired. The check is initiated upon a trigger, such as a timer, a sensed motion, or a user-initiated event such as when the user presses a button.
