Abstract: Methods and systems for performing a round trip time determination between two devices are described. An example method may include publishing, over a wireless network interface by a first device within a neighbor aware network (NAN) cluster, a schedule that invites devices within the NAN cluster to request, within a time window, to perform a round trip time (RTT) determination with the first device. The schedule may indicate that the time window begins at a time offset from a NAN discovery window and ends after a predetermined period of time has elapsed. The method may also include receiving a request, from a second device within the NAN cluster, to perform the RTT determination with the first device. The method may also include performing the RTT determination with the second device.

Abstract: A system and method for locating a network device. A location provider determines, based on location data, a location of a wireless access point. The location data includes location data from each of a plurality of network devices, wherein the location data for each network device includes the network device's location and data representative of a distance between the wireless access point and each network device. The location provider generates, based on the location of the wireless access point, location information for the wireless access point, signs the location information with a credential to form signed location information, and communicates the signed location information to the wireless access point.
