Figure 2-1 Cell of Origin In its simplest form, this technique makes no explicit attempt to resolve the position of the mobile device beyond indicating the cell with which the mobile device is (or has been) registered.

Depending on the accuracy requirements of the underlying business application, performance may be more than sufficient for casual location of mobile clients using the highest signal strength technique.

For instance, users intending to use location-based services only when necessary to help them find misplaced client devices in non-mission critical situations may be very comfortable with the combination of price and performance afforded by solutions using the highest signal strength approach.

In these cases, four or more receiving sensors are employed to perform To A multi-lateration.

Figure 2-3 Time of Arrival (To A) To A techniques are capable of resolving location in two-dimensional as well as three-dimensional planes.

To A tri-lateration makes use of three sensors to allow the mobile device location to be resolved with improved accuracy. The amount of time required for a message transmitted from station X to arrive at receiving sensors A, B, and C is precisely measured as t A, t B, and t C.

Given a known propagation velocity (stated as c), the mobile device distance from each of these three receiving sensors can then be calculated as DA, DB, and DC, respectively.

The intersection of the three circular plots resolves the location of station X as illustrated in .

In some cases, there may be more than one possible solution for the location of mobile device station X, even when using three remote sensors to perform tri-lateration.

When receiving cells provide received signal strength indication (RSSI) for mobile devices, the use of the highest signal strength technique can improve location granularity over the cell of origin.
