20100056133 | Data Compaction Techniques - Many areas of technology need highly accurate data compression to provide small, multifunctional devices. For example, in the area of communication governed by the IEEE 802.11 standards, a wireless device could significantly improve its performance by using its calibration data. Moreover, because of the increased mobility of users, a wireless device should be able to operate in different regulatory domains. This flexibility requires access to significant amounts of data regarding such regulatory domains. Advantageously, piecewise linear abstraction and/or mapping can be used to significantly reduce the amount of stored data while ensuring accuracy in reproducing the total data at a later point in time. | 03-04-2010 |
20120002704 | Measuring Received Signal Strength on Neighboring Frequencies of a Channel with Interference in a Wireless Device - System and method for operating a wireless narrowband receiver. A signal may be received on a channel of the wireless narrowband receiver. At least a portion of the signal may be received from a first wireless narrowband transmitter. The wireless narrowband receiver may implement an adaptive frequency hopping algorithm. It may be determined if interference is present on the channel and one or more errors are detected in receiving the signal. In response to determining that interference is present on the channel and one or more errors are detected in receiving the signal, received signal strength of one or more neighboring frequencies of the channel may be measured, and the resulting measurements may be stored in a memory. The measurements may be used to determine interference sources interference on the channel. | 01-05-2012 |

20140022050 | RELATIVE POSITIONING APPLICATIONS IN WIRELESS DEVICES - 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. | 01-23-2014 |

20140051460 | POSITIONING USING OBSERVER-BASED TIME-OF-ARRIVAL MEASUREMENTS - 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. | 02-20-2014 |
20140113674 | GROUP ASSOCIATION BASED ON NETWORK DETERMINED LOCATION - Systems, methods, and devices enable group associations based on network determined location information. The various embodiments enable the ad-hoc creation of mobile device groups based on network determined locations. In an embodiment, a server may determine the location of a mobile device and based on the mobile device being located in a pairing zone may add the mobile device to a group. In an embodiment, the server may add the mobile device to the group following the occurrence of a trigger event, such as the mobile device pausing in a given pairing zone for a period of time. In an embodiment, the server may identify that mobile devices are located within a pairing zone and may add all the mobile devices in the pairing zone to the same group. | 04-24-2014 |
20140222562 | LOCATION BASED DYNAMIC COUPONS - 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. | 08-07-2014 |
