Abstract:
1. A computing device including a processor and a memory including instructions that, when executed by the processor, are configured to cause the computing device to perform operations comprising: identifying at least three distance measurements by way of a packet-based time precision protocol, each distance measurement indicative of a distance between a first wireless device and a different one of a plurality of wireless devices; optimizing a set of weighting factors, each of the distance measurements associated with a corresponding weighting in the set of weighting factors; assigning at least one of the distance measurements a weighting according to an underlying wireless technology over which the respective distance measurement is determined; performing a weighted trilateration of the distance measurements weighted according to the weighting factors; and provisioning a location of the first wireless device according to the result of the weighted trilateration.
