  • Publication number: 20240113321
    Abstract: The present invention relates to lithium ion cells and specifically to lower capacity (3-10 Ah) elliptic cylindrical lithium ion cells with individual positive and negative terminals projecting from the top of the cell. In particular, the present invention relates to lower capacity elliptic cylindrical lithium ion cells with plastic compression seals, and method of processing them. The cells of the present application exhibit good charge retention and low internal resistance and can be employed for mission critical applications viz. powering satellites, launch vehicles, military vehicles, submarines and electric vehicles.

  • 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: 20240007882
    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: 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.
