  • Publication number: 20230057201
    Abstract: A user equipment (UE) is configured to perform a prewarming process, wherein the prewarming process includes concurrently performing a face detection process and an unlock process independent of face detection, determine whether a face detection operation indicates the presence of a face within a field of view of a camera of the UE and disable prewarming for a predetermined time period when the face detection operation is not satisfied.

  • Patent number: 10623994
    Abstract: In one embodiment, a computing device determines a plurality of probability-based trajectories a mobile device could traverse through a plurality of access point (AP) cells within a given area depending on an entry point of the mobile device into the given area. A predictive dwell time may also be associated to each AP cell based on how long a mobile device is expected to remain within the respective AP cell. Based on i) current locations of mobile devices, ii) the plurality of probability-based trajectories a mobile device could traverse through the plurality of AP cells, and iii) the predictive dwell time of each AP cell, the computing device can compute a probability of mobile device density surpassing a potential flash crowd threshold within each AP cell at any given future time. In response, the computing device may then perform one or more mitigation actions.

  • Patent number: 9788263
    Abstract: A hybrid wireless client apparatus including: a hybrid client controller, at least one antenna, and a plurality of shared and discrete components coupled to one another to form at least one transmit and receive chain each coupled to the at least one antenna for orthogonal frequency division multiplexed (OFDM) wireless communications with a wireless access point (WAP). The hybrid client controller is coupled to the plurality of shared and discrete components and configured to determine an eligibility of at least one neighboring wireless client node on a wireless local area network (WLAN) as a relay target, and responsive to an affirmative eligibility determination to initiate on the hybrid wireless client apparatus both local communications with the WAP together with a relay of distinct communications between the WAP and the at least one neighboring wireless client node as the relay target.

  • Publication number: 20170223502
    Abstract: Implementations of the present disclosure involve a system and/or method for indoor mapping. The indoor mapping system may receive wireless signals from wireless devices located in an area and create a wireless signal fingerprint that identifies each signal and the strength of the signal. A user may identify the location that the wireless signal fingerprint was taken on a geo-referenced map. After the wireless signal fingerprints for an area have been mapped, a user may determine a location by taking a wireless signal fingerprint and comparing the wireless signal fingerprint to previously taken wireless signal fingerprints.

  • Patent number: 9071972
    Abstract: An asynchronous access controller comprising a subscriber profiler, a piracy detector and a password injector. The subscriber profiler configured to aggregate both information about subscribers together with information about each associated WLAN. The piracy detector is configured to detect whether wireless communications usage of at least one of the WLANs exceeds at least one parameter specified in a service level agreement (SLA) with the associated subscriber. The password injector controller is configured to inject a new network access password into one or more of the nodes of the WLAN responsive to an affirmative determination by the piracy detector; whereby subsequent network access is selectively revoked on the WLAN in a manner which returns communications usage thereon into conformance with the SLA for the associated subscriber.

  • Patent number: 8750157
    Abstract: A diagnostic apparatus including a signal analyzer and a throughput projector for diagnosing a wireless home network. The signal analyzer analyzes wireless communication parameters at identifiable locations within a coverage area associated with the wireless home network. The throughput projector projects wireless throughput levels for at least one proposed wireless device differing in communication capabilities from the diagnostic apparatus at each of the identifiable locations, based on the communication parameters analyzed by the signal analyzer together with parameters which identify relative differences in communication capabilities of the diagnostic apparatus and the at least one proposed wireless device.
