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.

Encryption enhancement for multi-link operation in 802.11

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.

Selective spatial reuse to enhance network performance

Examples described herein provide automatic location of access points by a computing device. Examples may include receiving, by the computing device from each AP in a subset of a plurality of APs, a Global Navigation Satellite System (GNSS) signal measurement, and based on each received GNSS signal measurement, constraining, by the computing device, the map of relative AP locations by at least one translational degree of freedom or one rotational degree of freedom. Examples may include resolving, by the computing device, locations of the plurality of APs in the map of relative AP locations.

Automatic location of access points in a network

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.

Split multi-link system

Examples described herein provide wake-up of a network device. Examples include receiving, by a network interface of a first network device having a first Media Access Control (MAC) address, a request to wake-up a second network device having a second MAC address that is assigned to a same subnet as the first MAC address, and in response to the request, generating, by the first network device, a first wake-up frame having a destination address of the second MAC address and configured to cause the second network device to transition from operating in the first power mode to operating in the second power mode. Examples include transmitting, by the network interface of the first network device, the first wake-up frame to the second MAC address of the second network device.

Wake-up by a network device

An example network information aggregator is disclosed. The network information aggregator includes a network interface, a memory, and processing circuitry. The processing circuitry is to receive a machine learning model trained using initialization data from a model creation device. The processing circuitry is also to generate a device steering rule to steer a client device from a first radio to a second radio using the machine learning model. The processing circuitry is also to send a steer command to the first radio.

Adaptive wireless client steering

Some examples of handling FTM requests comprises receiving a plurality of fine timing measurement (FTM) requests from a second network device over a first channel. Determining a channel traffic along the first channel. Adjusting a FTM response frequency based on the channel traffic. Responding based on the FTM response frequency, to a first number of FTM requests out of the plurality of FTM requests.

Handling fine timing measurement requests

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.

Systems and methods for optimizing rate selection for transmissions during spatial reuse in WLAN networks

Systems and methods are provided for opportunistic spatial reuse. In various embodiments, the disclosed systems and methods provide for mechanisms for enabling and disabling spatial reuse in a wireless network as appropriate based on the deployment of the wireless network. In some embodiments, spatial reuse can be enabled and disabled based on various factors, such as channel utilization. In some embodiments, spatial reuse can be enabled and disabled as appropriate for various types of traffic in a wireless network. For example, spatial reuse can be enabled and disabled for downlink traffic (e.g., traffic from an access point to a client device), for uplink traffic (e.g., traffic from a client device to an access point), for multicast or broadcast traffic (e.g., traffic distributed to multiple recipients), or for certain modes of transmission (e.g., single user beamformed transmission, Dual Carrier Modulated transmission).

Opportunistic spatial reuse

Systems and methods are provided for aggregating Media Access Control (MAC) Protocol Data Units (MPDUs) destined for different peers, and may have the same or different source address information, e.g., within the same or across different virtual access points (VAPs). For example, trigger frames used to signal to devices which subchannel(s) those devices can utilize, may be aggregated. For example, a multi-VAP/multi-device block acknowledgement for acknowledging packets transmitted to devices belonging to different VAPs can be sent as an aggregated MPDU.

Optimized transmissions using A-MPDU and multi-VAP frames

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.

Optimizing service period negotiations in WLAN networks

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.

Spatial reuse for high priority traffic

Methods for assigning effective isotopic radiated power to an access point in a wireless network are provided. In one aspect, a method includes determining weights for neighboring access points in a wireless network based on channel frequency and basic service set color assignments. For a particular access point, a first path loss based on the determined weights and a second path loss based on the neighboring access points are calculated. First and second effective isotopic radiated power values are calculated based on the respective first and second path losses. The effective isotopic radiated power of the particular access point is adjusted based on the lower of the first and second calculated effective isotopic radiated power values. Systems and machine-readable media are also provided.

Basic service set color-based effective isotropic radiated power assignment for enterprise networks

An access point configured to manage client devices connected to the access point. The access point initiates an operational change. The access point generates an announcement to be included in a network frame based on the operational change. The announcement includes at least a list of neighboring access points with which the client devices can connect to and a first time period by which the client devices must connect to at least one neighboring access point included in the list of neighboring access points. The access point broadcasts the network frame to the client devices. Upon expiration of the first time period, the access point disassociates client devices that remain connected to the access point.
