First Claim
Patent Images
1. A method for transitioning between location technologies comprising the steps of:
- defining a perimeter threshold of an area;
tracking a location of a device using a first location technology when the device precedes the perimeter threshold; and
tracking the location of the device using a second location technology when the device exceeds the perimeter threshold.

Abstract
A perimeter threshold of an area is defined. The location of a device (102) is tracked using a first location technology (108) when the device (102) precedes the perimeter threshold. The location of the device (102) is tracked using a second location technology (100) when the device (102) exceeds the perimeter threshold.

- 16. A first device used for transitioning between location technologies, which when operable, defines a perimeter threshold of an area, tracks a location of a second device using a first location technology when the second device precedes the perimeter threshold, and tracks the location of the second device using a second location technology when the second device exceeds the perimeter threshold.
