    Abstract: A method for protecting 802.11 ax networks includes receiving, by an access point, a plurality of Single User (SU) Quality of Service (QOS) NULL frames from a station, tracking, by the access point as the plurality of SU QOS NULL frames are received, a variable in one or more of the plurality of SU QOS NULL frames, determining, by the access point and based on tracking the variable, the station is suspicious, sending, by the access point and in response to determining the station is suspicious, a request to check a status of the variable, determining, by the access point and based on a response to the request, the station is under attack, and flagging, by the access point, the station as under an attack.

    Abstract: Systems and methods for assigning BSS colors in a deployed wireless area network (WLAN) include identifying a plurality of APs of an external wireless network operating on a same channel as a deployed AP of a deployed wireless network; selecting as a subset of the plurality of APs of the external wireless network those APs of the external wireless network based on expected interference; grouping the APs of the subset of the plurality of APs by a basic service set (BSS) color used by each of the plurality of identified APs of the external wireless network to form AP BSS color groups; calculating an airtime utilization for each AP color group; and selecting a BSS color using the calculated airtime utilization and assigning the selected BSS color for use by the deployed AP of the deployed wireless network.

    Abstract: An example method for altering a transmission rate of a networking device. The example method comprises transmitting a first set of packets using first transmission characteristics represented by a first state of a finite state machine. The example method further comprises receiving information including a success status of transmission of the first set of packets. The example method also comprises updating, based on the received information, a weight of a first edge of the finite state machine, the first edge corresponding to a transition from a state representing prior transmission characteristics to the first state.

    Abstract: Example method includes: receiving, by a first access point, a plurality of beamforming feedback frames from a plurality of client devices in a WLAN; overhearing, by the first access point, a first beamforming feedback frame from a second access point; calculating, by the first access point, a second beamforming feedback frame in response to receiving a sounding frame transmitted from the second access point in the WLAN; selecting, by the first access point, a first subset of the plurality of client devices and the second access point as members of a MU-MIMO group; changing, by the first access point, a steering matrix corresponding to the MU-MIMO group based on both the received plurality of beamforming feedback frames and the calculated beamforming feedback frame to allow the first access point and the second access point transmit on a particular wireless communication channel simultaneously without interfering each other.

    Abstract: MU-MIMO provides a mechanism for a wireless network device to transmit to multiple client devices at the same time. When employing MU-MIMO, a network device may group two or more associated client devices, and transmit beamformed signals to each group. In some implementations, a network device may initiate channel sounding. Channel sounding may include transmitting sounding frames to client devices associated with two or more basic service sets. Channel sounding may facilitate beamforming transmissions to client devices associated with the two or more basic service sets. The network device may receive feedback frames from client devices associated with the two or more basic service sets. A feedback frame may indicate how a sounding frame was received. In some implementations, the network device may further construct a feedback table from the feedback frames. The feedback table may facilitate grouping of the client devices for beamforming transmissions.
