Abstract: Examples described herein mitigate adjacent channel interference for dual radios of a network device. Examples described herein may associate, by a network device, a first client device with a first radio of the network device, associate, by the network device, a second client device with a second radio of the network device, determine that the first and second client devices are within a steering threshold, and based on the determination that the first and second client devices are within the steering threshold, steer, by the network device, the second client device from the second radio to the first radio. Examples described herein may communicate, using the first radio of the network device, with the first and second client devices.

Abstract: Embodiments are directed to automatic location of access points in a network. An embodiment of one or more non-transitory computer-readable storage mediums includes instructions for transmitting a request from a computing device to multiple access points in a network to determine a distance between each pair of access points of the multiple access points; receiving at the computing device the determined distances between each pair of access points; generating a proximity matrix containing the determined distances between each pair of access points; solving the proximity matrix to automatically generate a set of locations for the multiple access points; and orienting the generated set of locations for the multiple access points based on known locations of one or more anchor points in a subset of the access points.

Abstract: Examples of techniques for dynamically controlling data bursts are described. In an example, an access point (AP) monitors a link quality between the AP and a client device associated with the AP. The AP determines a channel occupancy of a channel in which the AP is configured to operate. In response to determining that the channel occupancy is less than a channel busy threshold, the AP modifies a burst duration for traffic flow between the AP and the client device based on the link quality. The AP communicates with the client device using the channel for the modified burst duration.

Abstract: Examples of sensor-based roaming issue identification in a wireless network are disclosed. In an example, a wireless roam for a sensor may be initiated from a source AP to a target AP. Management traffic between the sensor and one of the source AP or the target AP during the wireless roam may be monitored. In response to detecting an anomaly in the management traffic, the wireless roam for the sensor from the source AP to the target AP may be re-initiated. Management traffic capture on the sensor during the reinitiated wireless roam may be initiated. A roaming issue for the sensor may be identified based on analysis of the captured management traffic and the same may be reported.

Responding based on the FTM response frequency, to a first number of FTM requests out of the plurality of FTM requests.

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: Systems and methods are provided for defining a split multi-link system. For example, the split multi-link system can define a multi-link device (MLD), where the MLD operates a first radio from a first AP of a plurality of APs and a second radio from a second AP of the plurality of APs through a Media Access Control (MAC) Service Access Point (SAP) of the split multi-link system. The first radio from the first AP and the second radio from the second AP may operate at different frequencies. The split multi-link system may also affiliate the first radio from the first AP and the second radio from the second AP with the MLD, where, using the MLD, the split multi-link system can transmit or receive one or more data frames from the MLD to a non-MLD or MLD client device using the first radio or the second radio.

Abstract: Examples of location determination of access points in a network are disclosed. In an example, a provisional proximity matrix comprising a measured distance between each pair of Access Points (APs) of a plurality of APs in a network is generated. Missing distances between one or more pairs of APs in the provisional proximity matrix are filled to generate a complete proximity matrix. A provisional deployment location map is generated for the plurality of APs based on the complete proximity matrix. Relative angles between paths connecting each pair of APs of the plurality of APs in the provisional deployment location map is determined. The filled distances in the complete proximity matrix are revised based on the relative angles to generate a corrected proximity matrix. A complete deployment location map for the plurality of APs is generated based on the corrected proximity matrix.

Abstract: Systems and methods are provided for transmitting low latency traffic in next generation wireless local area networks. A new Media Access Control (MAC) layer frame can be transmitted by an AP to establish a reserved time period during which interference from/collisions with other stations transmitting non-high priority data is avoided. Stations with non-high priority data queued for transmission can defer accessing a channel on which to effectuate the transmission until the reserved time period expires.

Abstract: Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, physical layer logic may implement a new preamble structure with a new signal field. Embodiments may store the preamble structure and/or a preamble based upon the new preamble structure on a machine-accessible medium. Some embodiments may generate and transmit a communication with the new preamble structure. Further embodiments may receive and detect communications with the new preamble structure.

Abstract: Systems and methods are provided for encryption enhancement for a multi-link operation. Various subsets of addresses (or all addresses) associated with the frame are set to a determined known value, allowing encryption of the mac protocol data unit (MPDU) at a controller without knowledge of which particular link the frames will be sent. The multi-link devices (MLDs) used in the above communication may conduct communications in compliance with the IEEE 802.11be standard.

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.

Abstract: Systems and methods are configured to receive a first request to schedule a Time To Wake (TWT) service period (SP) for a first station. The first request can be based on individual TWT protocol. That the TWT SP satisfies a threshold level of similarity with an existing TWT SP maintained for a group of at least one station scheduled to communicate over the existing TWT SP can be determined. The group can include a second station. The first station can be assigned to the group. A first packet can be transmitted to the first station and a second packet can be transmitted to the second station over the existing TWT SP.

Abstract: Logic may enable client devices or access points to relay medium access control (MAC) frames through a Wireless Fidelity (Wi-Fi) Direct network such as a network of Peer-to-Peer (P2P) connections to extend the wireless range of the devices or access points beyond the transmission range of the individual devices or access points. Logic may extend the range of IEEE 802.11 devices, such as IEEE 802.11ah devices, by allowing a station in the middle of two stations to serve as a relay station using the Wi-Fi Direct technology. Logic may enable relaying to avoid a full mesh technology such as is defined in IEEE 802.11s, since the full mesh technology may contain too many features that are not required for a simple or a static network configuration of such embodiments.

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: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.
