Intra-piconet location determination and tomography

摘要: A technique for intra-piconet location determination and tomography is described. This uses received signal strength indicator (RSSI) values in conjunction with transmitted power levels to determine the relative of each device within a small network employing frequency hopped spread spectrum transmission. In addition properties invention, geometry devices network, as well path loss information between pairs devices, may be used infer absorbers reflectors piconet. absorption reflection creating piconet tomography. The approach described this specification applied Bluetooth wireless Personal Area Network (PAN) locations, mitigate effects multi-path, perform indoor security functions, other application functions requiring cost-effective determination.
