摘要:
Systems, methods, devices, and computer program products are described for generating an aggregated group profile of access terminal users in an identified geographic region (e.g., at an entertainment venue). A group profile request may be received for a set of mobile access terminal users in the identified geographic region. User profile information may be requested for each of the users. User profiles may be aggregated to generate an aggregated group profile. The aggregated group profile may be distributed (e.g., for use in selecting advertisements at an entertainment venue to reflect the users currently in attendance).

Systems, methods, and devices for determining the geospatial position/location of a mobile device by using transmissions from surrounding wireless utility meters and prior knowledge of the locations of the surrounding meters. A mobile device may receive transmissions from a plurality of wireless utility meters, and determine signal strengths and meter identifiers of each of the plurality of wireless utility meters from the received transmissions. The signal strengths and meter identifiers may be compared to data records stored in a wireless utility meter signal signature database to identify a best match data record, which may include geographic coordinates that may be used by the mobile device to determine its current geospatial position and/or location.

摘要:
A method and apparatus for determining a location of a wireless device using radio waves and pressure measurements is disclosed. In one embodiment, a plurality of Radio Signal Strength (RSS) measurements are used to trilaterate an approximate location of the wireless device. The wireless device also takes pressure measurements that are compared with a second pressure measurement made by at least one other pressure sensor at a known elevation and in a local area near the wireless device. This comparison is used to generate an accurate estimate of the elevation of the wireless device. The accurate estimate of elevation may be combined with the RSS measurements to yield an accurate estimate of the location of the wireless device.

Systems, methods, and devices are described for determining a physical location of a wireless device. A receiver may be configured to receive associations between anchor locations and sensor nodes, wherein each sensor node uses near field communications to identify an anchor location. The receiver may also receive signal strength measurements from the wireless device measuring the signal strength of wireless sensor nodes. Arrangements may also be configured to determine physical locations of the sensor nodes based on physical locations of anchor locations and utilize received signal strength measurements with the determined physical locations of the sensor nodes to determine the physical location of the wireless device.

A collaborative method for a node includes forming a local network with at least one other node using a lower power subsystem; selecting a master node from among the local network based on a first set of criteria; and communicating with a back end server over a wireless wide area network (WWAN) using a higher power subsystem. An apparatus may include a first subsystem for communicating with a local network; and a second subsystem having an active mode and an inactive mode, the second subsystem for communicating with a wireless wide area network (WWAN) when in the active mode, the apparatus selecting the active mode or inactive mode based on a set of criteria.

Disclosed is a portable token device that may be used to assist a user in generating a PIN at one device and to then pass the PIN to another device such that the two devices can securely communicate with one another. The portable token device may include: an interface; and a processor. The processor may execute operations including: determining if a close proximity coupling through the interface to a first device has occurred; transmitting a PIN request to the first device; and obtaining a PIN. Further, the processor may determine if a close proximity coupling through the interface to a second device has occurred. If so, the processor may command transmitting the PIN to the second device. The second device may perform device registration with the first device based upon the received PIN.

Techniques for designing a sensor module that may be inserted into a container, for example, a box, for tracking RFID-labeled items enclosed in the container. In an exemplary embodiment, at least two planar surfaces are adjoined along a linear interface. Each of the planar surfaces supports a planar antenna whose radiation pattern may cover the volume of the container. A battery-powered tracking unit is attached to at least one of the planar surfaces to drive the planar antennas. In an exemplary embodiment, the planar antennas may be driven in succession to avoid collisions between the RFID communication signals, and for better RFID coverage of the items enclosed in the container.
