    Abstract: The present disclosure provides systems and methods for dynamically adjusting cell coverage sensitivity to address asymmetry of wireless cells that affect upstream and downstream traffic mismatch. In one aspect, a method includes estimating, at a network controller, one or more packet demodulation thresholds for an access point; sending, by the network controller, the one or more packet demodulation thresholds to the access point; receiving, from the access point, collected statistic, the collected statistics being link performance characteristics between the access point and one or more endpoints associated with the access point measured by one or more sensors associated with the access point; updating, at the network controller, the one or more packet demodulation thresholds based on the collected statistics to yield an updated packet demodulation threshold; and configuring, by the network controller, the access point with the updated demodulation threshold.

    Abstract: In one embodiment, a control device associated with a wireless network of a given location determines a reference quality of location readings between access points and client devices based on using substantially all of an available wireless communication bandwidth. The control device may then determine channel state information (CSI) between the client devices and access points for each orthogonal frequency-division multiple access (OFDMA) resource unit (RU), and selects a subset of RUs for allocation to each respective client device, based on the subset of RUs allocated to each respective client device i) surpassing a determined threshold of certain parameters of the CSI, while also ii) providing a minimum quality of a location reading based on using only the subset of RUs as compared to the reference quality of location readings. The control device may then allocate the selected subset of RUs to each respective client device for location-preserving OFDMA-signaling-based communication.

    Abstract: A first wireless device (e.g., an access point) receives a message from a second wireless device (e.g., a client device). The first device determines an angle-of-arrival of the message at a plurality of antennas of the first wireless device. The first device compares the angle-of-arrival with an angle-of-arrival threshold to determine whether to transmit a response message to the second wireless device. In one example, the first wireless device is a wireless access point device operating in a wireless network, the second wireless device is a wireless client device operating in the wireless network, the message is a probe request message and the response message is a probe response message.

    Abstract: Connection issue prediction may be provided. A computing device may receive first Channel State Information (CSI) for a first link associated with a client device. The first CSI may be collected when beamforming was trained on a second link associated with the client device. Second CSI may be received for the first link associated with the client device. The second CSI may be collected at a time subsequent to when beamforming was trained on the second link associated with the client device. A correlation between the first CSI and the second CSI may be determined to be below a predetermined threshold. A status of the beamforming performed on the second link associated with the client device may be set to stale in response to determining that the correlation between the first CSI and the second CSI is below the predetermined threshold.
