Abstract: A method and system for providing location services at a network edge is described. An AP can receive location information associated with a second AP in a location group. The AP can also receive client location data from the second AP and associated with a first client. From at least the received client location data, the AP can determine a location of the first client. The AP can then send the location of the first client to a location service.

Abstract: Presented herein are techniques to shield transmissions from being received and the information contained in them recovered by unwanted devices. Multi-user multiple-input multiple-output (MU-MIMO) techniques are employed, and in particular the spatial dimension aspects of those techniques. Shield nodes are controlled to transmit in a way to obscure the downlink streams transmitted by a wireless access point that are intended for a particular client device to anything outside of the shielded area, and also to obscure uplink streams from one or more client devices to the wireless access point to anything outside of the shielded area but allowing the uplink streams to be well received by the wireless access point.

Abstract: In a computer-implemented method for automated management of correspondence related to an insurance claim, an evaluation trigger (e.g., occurrence of a pre-scheduled time, a triggering event associated with the claim, and/or reception of an evaluation request from an application) may be detected and, in response, an evaluation may be performed. Performing the evaluation may include retrieving one or more data elements from a claims database, and/or generating evaluation output data by processing the retrieved data element(s) according to a first set of rules implemented by a rules engine. Based upon the evaluation output data, at least one action may be selected from among a set of potential actions. The set of potential actions may include automatically generating correspondence (or selected portions thereof) associated with the claim and scheduling a future evaluation. The selected action may then be performed using a second set of rules implemented by the rules engine.

Abstract: This technology allows for determining the location of client devices via radio scanning for triggered orthogonal frequency-division multiple access (“OFDMA”) uplinks. Access points (“APs”) are configured for OFDMA transmissions. A first AP transmits a trigger frame on particular channel to stations in the wireless network. Neighboring APs scan channels for trigger frames (“TF”). Upon detection of a TF, neighboring APs associate a station identifier with a frequency allocation, or resource unit, in the TF. The neighboring APs receive an OFDMA uplink from the stations, determine a received signal strength indicator (“RSSI”) value for each frequency allocation in the OFDMA uplink, and transmit the RSSI values with the associated station identifier to the first AP. The first AP determines the location of each station by mapping a distance value to the RSSI values.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for obtaining initial parameters for ultrasonic transducers around a calibration target. The calibration target can include a fish-shaped structure, sensors placed at different locations of the fish-shaped structure, a processor that receives sensor values from the sensors, and a transmitter that outputs sensor data from the calibration target based on the sensor values. The calibration target can be fixed at a particular position relative to the ultrasonic transducers by a filament coupled to both the calibration target and a support structure. Sensor data can be obtained from the calibration target at the particular position relative to the ultrasonic transducers, and relative locations of the sensors can be determined. Parameters for the ultrasonic transducers around the calibration target can be adjusted based on the sensor data and the respective locations of the sensors.

Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.

Abstract: A method may be provided. One or more packets from a client may be received, in a block based modulation environment, at one or more switchable antennas of an access point. The access point may have a plurality of switchable antennas. Each switchable antenna may have an antenna state. The plurality of switchable antennas may be switched among such that at least five of the antenna states are sampled. Angle of arrival of the client may be calculated based on the at least five of the antenna states.

A computing device may establish Multi-Access Point (AP) coordination between at least a first AP and a second AP. The first AP can determine an uplink operation is scheduled. When an uplink is scheduled, the first AP can switch its antenna to a narrow beamwidth.

After the uplink transmission, the first AP can then switch the antenna to a larger beamwidth for a next Multi-AP coordination operation.

Abstract: A location server collects from access points at known locations in a venue, which is represented by grid locations defined by parameters accessible to the location server, (i) ultra wideband (UWB) location measurements for a UWB location technology based on UWB transmissions from mobile devices in the venue, and (ii) non-UWB location measurements for non-UWB location technologies based on non-UWB transmissions from the mobile devices. The location server associates the non-UWB location measurements for the non-UWB location technologies with the grid locations, using the UWB location measurements as reference measurements. The location server populates location calibration records for the grid locations of the venue with the non-UWB location measurements associated with the grid locations. The location server calibrates the non-UWB location technologies at the grid locations based on the non-UWB location measurements in the location calibration records associated with the grid locations.

Abstract: Methods and systems for distinguishing between radar signals and Wi-Fi signals are provided. When a set of electromagnetic signals are received, various tests are performed on the signals to determine if the signals are associated with radar pulses or if the signals are more likely to be associated with stray WI-Fi signals or other non-radar interference. One such test relies on the relatively small variance of frequencies used by radar pulses when compared to the high variation of Wi-Fi signals. Another test relies on the relatively low peak to average power ratio of signals associated with radar pulses when compared to Wi-Fi signals. The tests described herein are an improvement on existing methods for distinguishing radar signals from Wi-Fi signals and result in less switching of Wi-Fi channels due to erroneously detected radar signals.
