System and method for location determination using signal differential

A system for location determination of a beacon tag using signal differential comprising:

• an input component configured to receive a first beacon at a plurality of receiving devices and receive a second beacon at the plurality of receiving devices, the second beacon being received subsequent to the first beacon;
• a processor coupled to the input component, the processor to:
• identify a plurality of first received signal strength indicator measurements associated with the plurality of receiving devices based on the first beacon;
• establishing a reference point for the beacon tag based on the plurality of first received signal strength indicator measurements;
• identifying a plurality of second received signal strength indicator measurements associated with the plurality of receiving devices based on the second beacon;
• determining a displacement of the beacon tag based on a first order difference of the second received signal strength indicator measurements to the first received signal strength indicator measurements, determining the displacement including reducing a mean interference based on the first order difference by canceling out interference components within the received signal strength indicator measurements during the first order difference calculation;
• and
• updating a location of the beacon tag relative to the reference point based on the displacement.
