    Abstract: Presented herein are techniques for scheduling Ultra-Wideband (UWB) anchors and mobile devices for client ranging. A control device can determine respective ranging priorities for a plurality of mobile devices, which are each assigned to at least one UWB anchor. The control device can obtain at least one collision mapping identifying, for a respective pair of the mobile devices, a collision probability that a UWB signal associated with a ranging procedure involving a first mobile device of the respective pair will collide with a UWB signal associated with a ranging procedure involving a second mobile device of the respective pair. The control device can establish a ranging schedule for the mobile devices and UWB anchors based on the respective UWB ranging priorities and the collision mapping(s). The control device can send at least one command to cause UWB ranging procedures to be performed according to the ranging schedule.

    Abstract: Presented herein are techniques to optimize wireless local area network access point beam settings. A method includes, during a survey period, causing a first access point and a second access point in a wireless local area network, to simultaneously transmit survey transmissions according to a predetermined sequence of transmission states, receiving, from a survey station that received the survey transmissions during the survey period, telemetry associated with the survey transmissions, the telemetry including a location of the survey station when the survey station received the survey transmissions, and after the survey period, controlling, based on the telemetry associated with the survey transmissions, the first access point to operate according to a first transmission state from among the transmission states and the second access point to operate according to a second transmission state from among the transmission states.

    Abstract: A method for adaptive presence-based radio configuration of access points in a venue includes defining a number of regions in the venue in which access points are deployed, each region having a center point, and assigning a first access point to a first region, positioned at the center of the first region. The method also includes affecting a first energy level in the first region, which corresponds to a power of a transmit signal emitted by the first access point, and assigning to the first region a configurable capacity value that determines an acceptable overlap constraint between the first energy level of the first region and an energy level of a neighboring region. The method further includes generating data describing a tessellation graph in which a possible map of the access points is formed using an iterative descent process based on the first energy level and the overlap constraint.

    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.
