Abstract: A method implemented in a first wireless device is described. The method includes transmitting a plurality of paging requests, receiving a first plurality of bit streams, and performing a first correlation, during a reception window, of each bit stream. When a correlation threshold is exceeded, a synchronization packet is transmitted, a bit stream received, and a second correlation performed. When a third time difference between a first time difference and a second time difference is within a predetermined time difference range, a plurality of poll packets is transmitted, a second plurality of bit streams received, and a third correlation is performed of each bit stream of the second plurality of bit streams with a second expected bit stream. The method further includes determining a correlation time of a maximum correlation value of each poll packet and determining the plurality of RTTs corresponding to the plurality of poll pockets.

Abstract: A method and Bluetooth mobile device are disclosed for geo-locating a plurality of target Bluetooth devices. In some embodiments, a method includes distinguishing between time delays associated with received response packets from different target Bluetooth devices based at least in part on Access Codes derived from unique lower address part (LAP) of the received response packets; and determining a location for each of the target Bluetooth devices based at least in part on the time delay associated with the response packet received from the target Bluetooth device.
