Claim Text:
1. A network device comprising: a plurality of antennas; signal reception logic operably connected to the plurality of antennas and configured to wirelessly receive packets transmitted by a station device and convert the packets to orthogonal samples; antenna switching logic configured to switch between the plurality of antennas during each occurrence of reception, by the signal reception logic, of a response packet transmitted multiple times from the station device, resulting in corrupted orthogonal samples for each occurrence of reception of the response packet; signal re-generation logic configured to, for each occurrence of reception of the response packet, re-generate ideal orthogonal samples based at least in part on a final uncorrupted reception of the response packet, by the signal reception logic via a single antenna of the plurality of antennas, as a final response packet from the station device; and location logic configured to generate a set of estimated locations for the station device by converting signal phase information, embedded in the corrupted orthogonal samples and the ideal orthogonal samples, into an estimated location of the station device for each occurrence of reception of the response packet.
