Abstract: In one aspect, a method performed by an access point in a wireless local area network (WLAN), includes receiving a first ranging request message from a first device and monitoring for a second ranging request message from a second device on a channel of the WLAN. The first ranging request message includes a device identifier of the first device and the second ranging request message includes a device identifier of the second device. In response to receiving the second ranging request message, the access point combines the device identifier of the first device, first timing information associated with the first ranging request message, the device identifier of the second device, and second timing information associated with the second ranging request message into a single ranging response message. The access point then broadcasts the single ranging response message on the channel of the WLAN.

Abstract: Methods and apparatuses are presented for obfuscating the locations of terrestrial wireless transceivers, including wireless access points and femtocells. According to some embodiments, a method may receive, by a mobile device, data for a terrestrial wireless transceiver, wherein the data includes location coordinates of the terrestrial wireless transceiver, and wherein the location coordinates include an error term. Additionally, the method may include determining the error term based on the data. Furthermore, the method may include determining a corrected location of the terrestrial wireless transceiver by removing the error term from the location coordinates. In some instances, the data can further include a unique identifier associated with the terrestrial wireless transceiver, and wherein the error term is further determined based on the unique identifier.

Abstract: Disclosed herein are techniques for timing synchronization between a first wireless device and a second wireless device. The techniques include sending a first message by the first wireless device to the second wireless device, obtaining a first timestamp at the first wireless device by the first wireless device, and receiving, by the first wireless device, a fine timing measurement frame from the second wireless device in response to the first message. The fine timing measurement frame includes at least a part of a second timestamp from the second wireless device. The techniques further include determining by the first wireless device that the first wireless device is not synchronized to the second wireless device based at least partially on the part of the second timestamp and the first timestamp.
