Abstract: Techniques for determining whether a mobile device crosses a boundary defined by a first wireless access point (WAP) and a second fixed location WAP are provided. A method according to these techniques includes receiving at a mobile device information defining a boundary defined by first and second fixed location WAPs the boundary being defined at least in part based on a ratio of a round trip time (RTT) between the mobile device and the first fixed location WAP to a ratio of a RTT between the mobile device and the second fixed location WAP determining the ratio of the RTT between the mobile device and the first fixed location WAP to a ratio of the RTT between the mobile device and the second fixed location WAP determining whether the mobile device has crossed the boundary and triggering an event in response to the mobile device crossing the boundary.

Abstract: A ranging operation between a first wireless device D1 and a second wireless D2 is performed by: sending (504), to the second wireless device, a data frame including a request for the second wireless device to report its actual SIFS duration to the first wireless device; determining (505) a time of departure (TOD) of the data frame; receiving (516), from the second wireless device, a response frame including SIFS information indicative of the actual SIFS duration of the second wireless device; determining (518) a time of arrival (TOA) of the response frame; and determining (522) a round trip time (RTT) of the data frame and the response frame using the TOD of the data frame, the TOA of the response frame, and the actual SIFS duration of the second wireless device. 501). Device D2 determines (508) the TOA of the received frame by capturing a time stamp, creates a response frame and determines (510) the TOD of the response frame, determines (512) ist actual SIFS duration, and embeds (514) the SIFS information into the response frame. The response frame is preferably an acknowledgement frame (ACK). Wireless devices D1 and D2 preferably include an SIFS database that stores a number of previously determined SIFS durations for the wireless device, one or more median SIFS durations for wireless device, and/or whether other wireless devices support ranging operations in accordance with the example embodiments. The exchange of ranging capabilities informs each of wireless devices D1 and D2 whether the other one supports capturing timestamps and/or is able to determine its own SIFS duration. In this manner, the ranging operations may be performed without estimating the SIFS duration of the second wireless device, thereby eliminating ranging errors resulting from uncertainties in the SIFS duration of the second wireless device.

Abstract: Techniques for determining whether a mobile device crosses a boundary defined by a first wireless access point (WAP) and a second fixed-location WAP are provided. A method according to these techniques includes receiving, at a mobile device, information defining a boundary defined by first and second fixed-location WAPs, the boundary being defined at least in part based on a ratio of a round trip time (RTT) between the mobile device and the first fixed-location WAP to a ratio of a RTT between the mobile device and the second fixed-location WAP, determining the ratio of the RTT between the mobile device and the first fixed-location WAP to a ratio of the RTT between the mobile device and the second fixed-location WAP, determining whether the mobile device has crossed the boundary, and triggering an event in response to the mobile device crossing the boundary.

Abstract: Methods, systems, computer-readable media, and apparatuses for location based dynamic coupons are presented. In some embodiments, location information for a plurality of users in an area associated with the network based positioning system is determined. The location information may be analyzed using a set of rules associated with the area to create an offer associated with a location within the area. The offer may then be communicated to one or more users. In alternate embodiments, user density may be used to create offers for users, and the offers may be directed toward influencing users to move from a high user density location to a low user density location.
