Abstract: Receiving Wireless Local Area Network (WLAN) packets from co-located access point radios and client device radios may be provided. First, a plurality of switchable gain devices corresponding to an auxiliary radio may be placed into a toggling state in response to the auxiliary radio being placed in a sniffer mode. Next, it may be determined that a primary radio is transmitting within a frequency range of a frequency band. Then, in response to determining that the primary radio is transmitting within the frequency range of the frequency band, a one of the plurality of switchable gain devices corresponding to the frequency band may be placed into a low gain state when the auxiliary radio is sniffing the frequency range of the frequency band.

Abstract: Backscatter Device (BKD) scheduling and, specifically, narrowband BKD excitation for multiple BKD scheduling may be provided. An AP may determine to transmit an excitation transmission to a plurality of BKDs. The AP may determine a trigger frequency for each of the plurality of BKDs, and the AP may transmit an excitation transmission comprising a plurality of excitation signals. Each excitation signal may have a frequency corresponding to one of the trigger frequencies for the plurality of BKDs. The plurality of excitation signals may be ordered for the plurality of BKDs to perform backscattering (i) concurrently; (ii) staggered in a single Transmit Opportunity; or (iii) a combination of (i) and (ii).

Abstract: Automatically changing Access Point (AP) system configurations for Power over Ethernet (PoE) adaptation and Radio Frequency (RF) power improvement on band edge channels, particularly for Wireless Local Area Networks (WLAN) may be provided. A PoE budget for an AP may be determined. Then, an evaluation of inputs associated with the AP may be performed. The evaluation may include determining an entity input from an entity associated with the AP, determining a client input from a client interfacing with the AP, and/or determining a device input from the AP. Next, a configuration of the AP may be determined based on the PoE budget and the entity input, the client input, and/or the device input. The operation of the AP may be altered based on the configuration.

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: Optimal determination of wireless network pathway configurations may be provided. 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. The first AP can then receive uplink transmissions from at least a client in the coverage area of the 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: Improving backscattering and, specifically, a physical Layer transmit mode for improving the Signal-to-Interference Ratio (SIR) of backscatter signals may be provided. A transmitter may determine a Backscatter Device (BKD) to send a transmission to for backscattering. The transmitter may determine a width of a puncture in the transmission. Next, the transmitter may transmit the transmission to the BKD. The transmitter may receive feedback from a receiver about decoding a backscattered signal generated using the transmission. The transmitter may adjust the width of the puncture for a subsequent transmission based on the feedback.
