    Abstract: Example implementations may relate to an occupancy sensing system. For example, the occupancy sensing system may collect connection data and traffic data related to electronic devices that connect to the networking device. The occupancy sensing system may determine a number of resident devices and a number of high-traffic devices, based on the connection data or the traffic data. The occupancy sensing system may determine a number of the electronic devices that are coactive within an analysis time window, and may constrain the number of coactive electronic devices to a range from the number of high-traffic devices to the number of resident devices to generate an occupancy value.

    Abstract: An example communications device includes communications circuitry and control circuitry. The communications circuitry may wirelessly communicate with client devices. The control circuitry may determine signal-to-interference-plus-noise ratios (SINRs) for the client devices based on compressed client-side channel state information received from the client devices. The control circuitry may assign the client devices to multi-user-multiple-input-multiple-output (MU-MIMO) groups based on the SINRs.

    Abstract: An example communications device includes communications circuitry and control circuitry. The communications circuitry may wirelessly communicate with multiple receiver antennas concurrently via multiple transmit antennas. The control circuitry may execute an adaptive sounding process that may include, for each client connected to the communications device, performing a follow-up sounding for the client in response to determining that all of the following conditions are jointly satisfied: (a) a wireless channel of the client has significantly changed, as determined based on a channel correlation metric; (b) a wireless throughput has significantly decreased, as determined based on a throughput gradient metric; and (c) the client had a significant amount of recent traffic, as determined based on a traffic metric.

    Abstract: This disclosure provides systems through which a wireless access point (AP) can determine the location of a client device with a high degree of accuracy. The AP uses CIR measurements for a plurality of directional beams used to communicate with the client device to determine a respective amplitude of a Line-of-Sight (LOS) path between the AP and the client device for each beam. The AP identifies a high-LOS-amplitude subset of the beams and, based on predefined radiation patterns associated with the beams included in the high-LOS-amplitude subset, determines a direction of the LOS path between the AP and the client device. The AP also determines a Time-of-Flight (ToF) for radio frames exchanged between the AP and the client device via the plurality of directional beams and uses the ToF to determine a distance between the AP and the client device.

    Abstract: Examples described herein include receiving an indicator of the quality of a wireless signal between an access device and a computing device, determining an upper data transfer rate from the indicator, and determining a range of data transfer rates. The range may include the upper data transfer rate and a second data transfer rate. Examples disclosed herein also include evaluating a throughput at the upper data transfer rate based on an error rate at the upper data transfer rate and evaluating a throughput at the second data rate based on an error rate at the second data transfer rate. Examples disclosed herein also include determining a peak data transfer rate within the range of data transfer rates based on the throughputs.
