  • Patent number: 12376159
    Abstract: Groups of Wi-Fi 7 stations are created including identifying Wi-Fi 7 stations accessing the channel for multimedia traffic and creating a group of stations accessing the channel for multimedia traffic. Responsive to reaching the threshold usage for channel usage, a high usage priority mode is activated to prioritize multimedia traffic. In high usage priority mode, notifying the group of Wi-Fi 7 stations of EDCA channel contention parameters using broadcast, management action frame, including notifying the group of multimedia Wi-Fi 7 stations. Values of EDCA parameters in the broadcast management action frame for the at least one multimedia group are modified during high usage to allow more aggressive contention to the at least one multimedia group with multimedia traffic.

  • Patent number: 12376136
    Abstract: A threshold usage of the primary channel transmission bandwidth is detected exceeding a predetermined value, triggering a second mode. Responsive to reaching the threshold usage detection, a puncturing pattern is activated to transmit data frames over the remaining channel transmission bandwidth while continuing to transmit management frames over the primary channel transmission bandwidth. Responsive to reaching the threshold usage detection, data packets are separated using RU allocations for multiple wireless clients over the remaining channel transmission bandwidth. Data packets are then transmitted according to bandwidth limitations and spectral limitations.

  • Patent number: 12363567
    Abstract: A capture group of access points formed from the plurality of access points dedicate at least one radio from each of the access points for capturing data packets. Captured data packets are received by wireless transmission from each of access point of the capture group of access points. The access points of the capture group are preferably geographically dispersed to increase capture range. The captured data packets are analyzed to identify a set of multiuser data packets. To do so, the set of multiuser data packets is checked against a set of rules for multiuser data packets to troubleshoot wireless network issues.

  • Publication number: 20240224310
    Abstract: A size of a data packet being transmitted downlink to a specific Wi-Fi 7 client is determined from real-time data traffic. A number of small tones and large tones needed in combination for the data packet transmission, either alone or in combination, is calculated. The combination of small RU tones and large RU tones is allocated to the specific wireless client for use in downlink. The data packet is transmitted downlink to the Wi-Fi 7 client across the combination of small and large RU tones.

  • Publication number: 20240007942
    Abstract: A probe request sent from a Wi-Fi 6E wireless client to the legacy access point is received by a Wi-Fi controller. To process, a Wi-Fi 6E access point for connection from the plurality of access points, proximate to the Wi-Fi 6E wireless client is selected for service. Reduced Neighbor Report (RNR) RNR information is collected about the Wi-Fi 6E access point by the access point the Wi-Fi 6E wireless client. The RNR information is transmitted to the legacy access point, wherein the legacy access point forwards the RNR information to the Wi-Fi 6E wireless client as part of a probe response sent responsive to the probe request. A subsequent probe request is detected, sent from the Wi-Fi 6E wireless client to initiate association with the Wi-Fi 6E access point using the RNR information.

  • Publication number: 20230422037
    Abstract: An unauthorized access point is identified during a periodic scan on the wireless network and storing a MAC address for the unauthorized access point and monitored for connection attempts. The unauthorized access point, due to having a hidden SSID, is monitored by the MAC address for data packets sent and received. At least one client associated to the unauthorized access point is identified from the data packets by MAC address. The at least one client is monitored, by the MAC address, for a probe request sent to the unauthorized access point. Responsive to detecting the probe request, an SSID of the unauthorized access point is parsed. A security action on the unauthorized access point using the SSID.

  • Patent number: 11601813
    Abstract: Broadcasts of a probe request are detected from a wireless station with the MAC address for an unauthorized access point in order to begin association between the wireless station and the unauthorized access point. Responsive to the probe request detection, a spoofed probe response is transmitted including a MAC address of the unauthorized access point to the station to appear as if sent by the unauthorized access point. The probe response includes a NAV element and the MAC address of the unauthorized access point, the NAV element set at a value high enough to prevent the station from transmitting to the unauthorized access point during a period.

  • Patent number: 10785703
    Abstract: An unauthorized access point is identified during a periodic scan on the wireless network and storing a MAC address for the unauthorized access point and monitored for connection attempts. In response to an attempt by the unauthorized access point to connect to a wireless station or in response to the wireless station attempt to connect to the unauthorized access point, a spoofed probe response is transmitted to prevent a connection. The probe response can include a channel switching element and the MAC address of the unauthorized access point.
