Abstract
An access point includes first and second radios that operate in accordance with first and second wireless protocols, respectively. The access point performs a method including receiving a first protocol packet of the first wireless protocol and a second protocol packet of the second wireless protocol transmitted by a wireless device over a communication channel, and measuring a first received power of the first protocol packet and a second received power of the second protocol packet at the access point. The method further includes determining whether reception times of the first protocol packet and the second protocol packet are within a coherence time for the communication channel and, when the reception times are within the coherence time, combining the first received power and the second received power into a multiprotocol received power. The method also includes determining a location of the wireless device based on the multiprotocol received power.
