Abstract: Improved mesh performance using Overlapping Basic Service Set (OBSS) coloring and transmission scheduling may be provided. A controller may determine that a plurality of Access Points (APs) in a mesh network each have a Received Signal Strength Indicator (RSSI) that is in a predetermined range. Next, the controller may assign, in response to determining that the plurality of APs each have the RSSI that is in the predetermined range, OBSS colors to links between the plurality of APs to limit packet collision in the mesh network between the plurality of APs. The controller may then create a transmission schedule for transmissions between the plurality of APs in the mesh network based on the assigned OBSS colors.

Abstract: Optimal determination of wireless network pathway configurations may be provided. A computing device may detect, at a first network Access Point (AP), inference on a channel with a second AP. Then, the computing device can check availability of a redundant radio at the second AP. Based on the availability, the computing device can establish a new radio link with the redundant radio at the second AP and reroute data traffic over the new radio link to the second AP. After establishing the new radio link, the computing device can then sever the channel with the second AP.

Abstract: In one embodiment, a supervisory service for a wireless network computes a compressive sensing schedule for a plurality of sensors in the wireless network. The service sends target wake time (TWT) messages to a subset of the plurality of sensors according to the computed compressive sensing schedule. The service receives, in response to the TWT messages, sensor readings from the subset of the plurality of sensors. The service performs compressive sensing on the received sensor readings.

Abstract: In one embodiment, a device in a wireless network receives a target wake time (TWT) request from a wireless client. The device computes TWT parameters based on the received request. The device predicts, using the computed TWT parameters as input to a machine learning model, whether the computed TWT parameters will be accepted by the wireless client. The device provides the computed TWT parameters to the wireless client, based on a prediction by the machine learning model that the client will accept the computed TWT parameters.

Abstract: In one embodiment, a device obtains a machine learning model indicative of how to focus on particular location information from a plurality of radio frequency (RF) elements to provide an accurate location estimate of a wireless client based at least in part on angle-of-arrival information of the wireless client. When the device then obtains location information regarding the wireless client from the plurality of RF elements, it may apply the machine learning model to the location information regarding the wireless client to focus on particular location information of the location information from the plurality of RF elements. The device may then estimate a physical location of the wireless client based on focusing on the particular location information during a locationing computation.
