Abstract
There is described a system and method for location determination of a beacon tag using signal differential. A first beacon is received at multiple receiving devices. First received signal strength indicator measurements associated with the receiving devices are identified based on the first beacon. A reference point for the beacon tag is established based on the plurality of first received signal strength indicator measurements. A second beacon is received at the receiving devices. The second beacon is received subsequent to the first beacon. Second received signal strength indicator measurements are received at the receiving devices are identified based on the second beacon. A displacement of the beacon tag is determined based on a first order difference of the second received signal strength indicator measurements to the first received signal strength indicator measurements. A location of the beacon tag relative to the reference point is updated based on the displacement.
