Abstract: A method for network-based positioning of a mobile device as described herein includes selecting a first set of access points (APs) to take first positioning measurements from the mobile device; obtaining the first positioning measurements from the first set of APs; selecting, based on the first positioning measurements, a second set of APs to take second positioning measurements from the mobile device; obtaining the second positioning measurements from the second set of APs; and determining a location of the mobile device based on the first positioning measurements and the second positioning measurements.

Abstract: Methods and apparatuses are disclosed that may perform simultaneous ranging operations between a requester device and each of a plurality of target devices using OFDMA-based frame exchanges while maintaining a level of accuracy comparable to ranging operations that do not use OFDMA-based frame exchanges. Tone interleaving may be used so that the ranging devices may estimate channel conditions for the full frequency spectrum of the wireless medium. For example, a unique set of two or more non-adjacent groups of OFDM sub-carrier frequencies may be allocated to each of the plurality of target devices for ranging operations.

Abstract: A method of determining a position of a target device includes: sending a first measurement signal from a first known-position device; receiving the first measurement signal at a second known-position device; receiving a first acknowledgement signal from the target device at the first known-position device and at the second known-position device; determining the position of the target device using first timing information associated with the first measurement signal and the first acknowledgement signal, a first position of the first known-position device, and a second position of the second known-position device.

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.
