  • Publication number: 20240129862
    Abstract: Automatically changing Access Point (AP) system configurations for Power over Ethernet (PoE) adaptation and Radio Frequency (RF) power improvement on band edge channels, particularly for Wireless Local Area Networks (WLAN) may be provided. A PoE budget for an AP may be determined. Then, an evaluation of inputs associated with the AP may be performed. The evaluation may include determining an entity input from an entity associated with the AP, determining a client input from a client interfacing with the AP, and/or determining a device input from the AP. Next, a configuration of the AP may be determined based on the PoE budget and the entity input, the client input, and/or the device input. The operation of the AP may be altered based on the configuration.

  • Publication number: 20240072828
    Abstract: Improved Radio Frequency (RF) performance by optimizing temperature may be provided. A plurality of heatmaps may be created associating a plurality of component heat characteristics, of a plurality of components of a device, with a plurality of pre-defined performance trade-off states. Next, a shortest path through the plurality of pre-defined performance trade-off states may be determined. The device may then be placed in successive ones of the plurality of pre-defined performance trade-off states according to the determined shortest path until a Transmit (TX) performance target is met.

  • Publication number: 20240056226
    Abstract: A network of access points (AP) in a high-density environment may be provided. A number of packet transmission retries for one or more of the AP may be determined by setting a number, m, of retries for transmitting a data packet, where m is the upper limit of the number of retries. Data packets are then transmitted m times. Upon transmitting the data packet m times, a success probability SP(u,m) for transmission of the data packet, where u is the number of users, may be calculated. The transmission of the data packet may be repeated m?x times where x is an integer. Upon calculating the success probability for m?x times, a success probability SP(u,m?x) for transmission of the data packet may be calculated. If SP (u,m?x) is larger than SP(u,m) then x may be decreased by one and actions (b)-(f) may be repeated. If SP (u,m?x) is not larger than SP(u,m) then m?x may be set as the maximum number of retries for the data packet.

  • Patent number: 11902912
    Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.

  • Publication number: 20240049133
    Abstract: Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority.

  • Publication number: 20240023040
    Abstract: Coordinated Orthogonal Frequency Division Multiple Access (C-OFDMA) in high density networks may be provided. A primary Access Point (AP) and a subordinate AP may be caused to use an omnidirectional antenna pattern during a synchronization period. Next, the primary AP and the subordinate AP may be caused to use an omnidirectional antenna pattern during a time in which the primary AP sends a subordinate Trigger Frame (TF) during a first C-OFDMA period. The primary AP and the subordinate AP may then be caused to use a directional antenna pattern during times in which the primary AP and the subordinate AP Uplink (UL) data during the first C-OFDMA period and Downlink (DL) data during the first C-OFDMA period.

  • Patent number: 11678205
    Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.

  • Patent number: 11659559
    Abstract: Optimal determination of wireless network pathway configurations may be provided. A computing device may establish Multi-Access Point (AP) coordination between at least a first AP and a second AP. The first AP can determine an uplink operation is scheduled. When an uplink is scheduled, the first AP can switch its antenna to a narrow beamwidth. The first AP can then receive uplink transmissions from at least a client in the coverage area of the narrow beamwidth. After the uplink transmission, the first AP can then switch the antenna to a larger beamwidth for a next Multi-AP coordination operation.

    Abstract: Receiving Wireless Local Area Network (WLAN) packets from co-located access point radios and client device radios may be provided. First, a plurality of switchable gain devices corresponding to an auxiliary radio may be placed into a toggling state in response to the auxiliary radio being placed in a sniffer mode. Next, it may be determined that a primary radio is transmitting within a frequency range of a frequency band. Then, in response to determining that the primary radio is transmitting within the frequency range of the frequency band, a one of the plurality of switchable gain devices corresponding to the frequency band may be placed into a low gain state when the auxiliary radio is sniffing the frequency range of the frequency band.
