Abstract:
1. A wireless boundary system for tracking a location of a movable device in a generally circular user-defined roaming area comprising: a base unit including a base transceiver unit, an oscillator and a component for reducing clock speed variation, a location of said base unit defining a center point of said generally circular user-defined roaming area with a radius of said user-defined area being defined by a user during system set-up; at least one movable device trackable within said roaming area and having a movable device transceiver unit in signal communication with said base unit transceiver unit, said movable device transceiver unit being incorporated within a PCB assembly that includes a movable device oscillator and a movable device component for reducing clock speed variation between the movable device and the base unit; said system configured to continuously obtain distance values between the base unit and the movable device on a real time basis using said transceiver units and to calculate a current estimate of a distance between the movable device and the has on an ongoing basis.
