  • Publication number: 20240023179
    Abstract: An arrangement of three radios maybe provided. The three radios define first and second outer data links and a middle data link. Access to the arrangement of three radios can be biased to the middle data link in one direction upon a data transmission through the first and second outer data links being dominate in an opposite direction. Data transmission with enhanced multi-link single radio (eMLSR) client devices can be prioritized lower than data transmission with simultaneous transmit and receive radio (STR) client devices and non-simultaneous transmit and receive radio (NSTR) client devices. A radio can be configured for data transmission with a client device. The range of the radio is limited when the data traffic through the radio exceeds a determined number of bytes of data in a determined amount of time.

  • Patent number: 11838862
    Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

  • Publication number: 20230379064
    Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

  • Patent number: 11818706
    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.

  • Publication number: 20230328624
    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.

  • Patent number: 11722931
    Abstract: Mitigation of active link alternation by multi-link devices (MLDs) may be provided. First, at least first and second links may be established between an Access Point (AP) MLD and an associated MLD client. The first link may be active, while the second link may be inactive. A set of traffic load data associated with the links may be collected before and after transmission of a Basic Service Set (BSS) load report to the MLD client. The report may include a traffic load on the second link prior to transmission, where the second link is less loaded than the first link. Based on the collected traffic load data, an active link alternation from the first to the second link by the MLD client responsive to receiving the report may be detected. One or more methods for BSS load report management may then be applied to mitigate future active link alternation.

  • Patent number: 11716632
    Abstract: Coordinated Frequency Division Multiplexing (FDM) Transmission Opportunity (TXOP) sharing may be provided by determining that at least two Access Points (APs) of a wireless network support coordinated FDM TXOP sharing. In response to the determination that the at least two APs support coordinated FDM TXOP sharing, at least one of: a first bias is applied to a channel assignment algorithm to promote an assignment of overlapping channels of the at least two APs, and a second bias is applied to the channel assignment algorithm to promote an assignment of adjacent channels of the at least two APs. Next, channels are assigned to the at least two APs based on an output of the channel assignment algorithm.

  • Patent number: 11716652
    Abstract: Systems, methods, computer-readable media, and devices are disclosed for collecting access point telemetry. A first access point is identified that is associated with a single instance on a pod. A hash identifier is identified, where the hash identifier identifies a radio frequency (RF) neighborhood of the first access point based on a geographical location of the first access point. Subsequent access point members of the RF neighborhood are dynamically determined by dynamically assigning a second access point to the RF neighborhood, the dynamic assignment based on the second access point being within a threshold geographical location to the first access point. Telemetry from the second access point is directed towards the single instance on the pod, where the pod receives telemetry for all access points in the dynamically determined RF neighborhood.
