Abstract
The present subject matter discloses a method for estimating dilution of precision (DOP) across a service area. A Monte Carlo simulation is used to determine the DOP across a service area. Random points are selected across a service area and as well as the radio transmitters who signals are capable of being received at the random points are determined. Using the network topology of radio transmitters, a DOP is calculated for each of the random points. DOP is modeled for the service area as a function of the calculated DOP for each of the random points. The modeled DOP is used to determined the measurement accuracy required for subsequent location requests.

6. A method of optimizing the number of measurements requested in a service area, comprising:
-
selecting a level of uncertainty; determining a set of radio transmitters that transmit signals capable of being received in the serving area; determining a metric across the service area based on at least the geometry of each of the radio transmitters within the set with respect to a plurality of randomly distributed points across the area; and determining the number of measurements required at a location within the area based on at least the metric and the level of uncertainty. - View Dependent Claims (7, 8, 9, 10, 11, 12)
