  • Publication number: 20110269478
    Abstract: An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.

  • Publication number: 20110246148
    Abstract: The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.

  • Publication number: 20110211444
    Abstract: A communication system enables a node to utilize multiple communication interfaces to connect to an overlay network. The use of multiple communication interfaces provides a redundant overlay network connection, thereby enabling a node to maintain connectivity or select a preferred connection to the overlay network, increasing efficiency or reducing costs in the overlay network. A network in which member nodes obtain services in the absence of server-based infrastructure is referred to as a “peer-to-peer overlay network” (or “overlay network” or simply “overlay”). Overlay networks consist of several nodes from hundreds, to thousands, joined together in a logical routing structure. Individual nodes often participate in routing and maintenance aspects of the overlay. Typically an overlay is formed through the enrollment and joining of all these nodes as defined by the overlay protocol. Nodes forming peer-to-peer overlay networks may communicate with each other over various network technologies.

  • Publication number: 20110183683
    Abstract: The subject matter disclosed herein relates to a system and method for receiving, by a first mobile station, a signal transmitted from a second mobile station and addressed to a communication device (e.g., a communication device having a known location). The signal comprises a location estimate for the second mobile station. A range from the first mobile station to the second mobile station is estimated based at least in part on a measured signal strength of the received signal.

  • Publication number: 20110179027
    Abstract: A database of the location based relationships of points of interest within an environment is automatically generated using a digital representation of the environment that includes the points of interest at different locations within the environment. The locations of the points of interest in the environment are identified and the location based relationships between the points of interest are determined. The points of interest are labeled with the determined relationships and the points of interest and labeled relationships are stored. For example, a graph structure may be produced where each node is a point of interest and the edges between nodes is labeled with the determined relationships.

  • Publication number: 20110176468
    Abstract: A time-of-propagation distance-determining method involves sending a probe request from a handset to an AP and receiving a return ACK. The time it takes for the probe request to propagate to the AP, the turnaround time, and the time it takes the ACK to propagate back to the handset is measured on the handset. The turnaround time is subtracted from the measured time, and the result is used to make a distance determination. In order to reduce power consumption, the “lowest overall transmit energy” setting that will give acceptable reception of a probe request sent by the handset to the AP station is determined. The lowest overall transmit energy setting involves a bit rate setting and a transmit power setting. The lowest overall transmit energy setting is used to send probe requests when probe requests are sent from the handset in carrying out a time-of-propagation distance-determining transaction.
