Abstract: Techniques are provided for utilizing reference signals transmitted by network stations to determine the orientation of a wireless node. An example method for determining an orientation of a user equipment includes determining a first location associated with the user equipment, determining a second location associated with a first wireless node, receiving, with the user equipment, a radio frequency signal transmitted from the first wireless node, determining two measurements based at least in part on the first location, the second location, and angle of arrival information associated with the radio frequency signal, determining a gravity vector based on inertial measurements obtained with the user equipment, and computing the orientation of the user equipment based at least in part on the gravity vector and the two measurements.

Abstract: Disclosed are a system, apparatus, and method for adaptive discovery and scanning of wireless access points. In one embodiment, a set of channels can be scanned in a first iteration to discover wireless access points. In one embodiment, a discovery profile based on the discovered wireless access points can be determined and in a second iteration, a subset of the set of channels can be scanned. In one embodiment, the subset consists of non-overlapping channels selected according to the discovery profile.

Abstract: Navigation solutions for a pedestrian or vehicle user are obtained by determining whether the direction and location of the user obtained from a map at least substantially conform to the direction and location of the user based on one or more measurements obtained from one or more sensors, and if the direction and location of the user obtained from the map at least substantially conform to the direction and location of the user based on one or more measurements obtained from one or more sensors, computing the navigation solutions based, at least in part, on the direction and location of the user.

Abstract: Methods, apparatuses, and/or articles of manufacture are disclosed, which may be employed in a mobile device communicating with a transponder via a near field communications channel. In one example, round trip time of a message may be computed to estimate processing latency contributed by processes occurring within the mobile device and/or the transponder.
