Abstract

A system and method for determining the positioning of mobile-appliance location determining sensors in a mobile-appliance communications network by estimating the positioning accuracy of the sensors.

Claims

1. In a mobile-appliance communication system with plural base stations, a method of positioning location sensors for determining the location of a mobile-appliance within a predetermined accuracy, the improvement comprising the steps of:

positioning the location determining sensors at some but not all of the plural base stations to minimize the number of location determining sensors, the positioning being a function of an estimated accuracy of the location calculated by the location determining sensors; and

positioning the location determining sensors at some but not all of the plural base stations to minimize the number of location determining sensors, the positioning being a function of the costs of the location determination sensors.

2. The method of claim 1, wherein the location determining sensors are positioned as a function of minimizing the number of sensors required for a signal coverage area.

3. The method of claim 1, wherein the location determining sensors are positioned as a function of a selected capability of the sensor.
