Abstract: Examples described herein provide channel assignments for ranging between network devices in a network during beacon intervals. Examples described herein may assign a plurality of channels to a plurality of network devices based on a plurality of channel assignment permutations, and initiate, during beacon intervals, ranging measurements between the plurality of network devices on the plurality of channels based on each of the channel assignment permutations to generate ranging results. Examples described herein may determine whether total ranging measurements are performed for a threshold percentage of available links between the plurality of network devices on the plurality of channels, wherein the total ranging measurements include the ranging measurements based on each of the channel assignment permutations. Examples described herein may, based on a determination that the total ranging measurements are performed for the threshold percentage of available links, resolve locations of the plurality of APs based on the ranging results.

Abstract: Systems and methods are provided for optimizing resource consumption by bringing intelligence to the key allocation process for fast roaming. Specifically, embodiments of the disclosed technology use machine learning to predict which AP a wireless client device will migrate to next. In some embodiments, machine learning may also be used to select a subset of top neighbors from a neighborhood list. Thus, instead of allocating keys for each of the APs on the neighborhood list, key allocation may be limited to the predicted next AP, and the subset of top neighbors. In some embodiments, a reinforcement learning model may be used to dynamically adjust the size of the subset in order to optimize resources while satisfying variable client demand.

Abstract: Systems and methods are provided for using a short data frame sent at a particular rate that can be used to probe a channel on which an access point is operating. The rate can be increased/decreased depending on whether or not transmission of the short data frame was successful or not. In this way, the highest possible rate (which can be impacted by any or all of the following factors: number of spatial streams, modulation and coding scheme, channel bandwidth, guard interval) can be selected to transmit data on the channel. In other words, a transmission rate can be selected dynamically and on a per-packet basis for a spatial reuse data frame that would follow the short data frame based on whether transmission of the short data frame was successful.

Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for reducing channel access latency via selective application of SR for latency-sensitive and high-priority traffic. If a radio frequency (RF) signal is detected on a channel used by an access point (AP) or a client device, a determination can be made as to whether the energy of the RF signal relative to SR energy level thresholds permits transmission on that channel used simultaneously by another, e.g., neighboring AP. If so, frames can be transmitted so long as the other neighboring AP is associated with a different basic service set (BSS) color than that of the AP, and so long as the frames to be transmitted belong to a high-priority/low-latency traffic access category.

Abstract: Examples described herein provide ranging by a network device during a beacon interval. Examples described herein may discover, by a network device during a first beacon interval, a plurality of APs in a network that are capable of ranging and a received signal measurement of each of the plurality of APs. Examples described herein may select, by the network device, an AP with a strongest received signal measurement among the plurality of APs, determine, by the network device, whether the selected AP is available for ranging, and based on a determination that the selected AP is available for ranging, initiate, by the network device during a second beacon interval, ranging measurements with the selected AP to generate a ranging result. Examples described herein may, based on the ranging result, resolve locations of the plurality of APs.

Abstract: Embodiments are directed to intelligent scheduling of Wi-Fi services for applications. An embodiment of computer-readable storage mediums includes instructions for receiving data packets from multiple connected devices at a wireless access point and identifying an application traffic flow for each data packet; assigning each data packet to a respective queue of a first set of queues based on an identified application traffic flow for each data packet; selecting data packets from the first set of queues based on priorities for each of multiple applications; generating prioritized candidate lists for selected data packets in a second set of queues, each queue being dedicated for an access category for one or more application; and scheduling data packets from the candidate lists, including selecting a transmission mode for each access category based on characteristics of the one or more applications.

Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.
