Abstract: Systems and methods are provided for implementing a coexistence coordinator in an access point (AP) operating in a Internet of Things (IoT) network. The coexistence coordinator coordinates transmission of both IoT-related data from an IoT radio and WiFi data from a WiFi radio, the IoT radio and the WiFi radio coexisting in the AP. The coexistence coordinator synchronizes time between the WiFi radio and the IoT radio so that times during which IoT-related data is to be sent from the IoT radio (in accordance with Time-Division Multiple Access (TDMA) channel access method) can be determined. Operation of the WiFi radio is suspended during those times when the IoT-related data is transmitted from the IoT radio.

Abstract: A method of adjusting a link in a wireless communication system is described. The method includes monitoring a communication channel by a network device in a wireless local area network. The method also includes detecting a signal identified as being transmitted by an unmanned aerial vehicle on the communication channel. The method further includes transmitting a signal with a duty cycle having a predetermined value in the communication channel and monitoring a received signal strength indicator of the signal identified from the unmanned aerial vehicle. In some embodiments, the transmitted signal includes one or more of an interference signal, a de-authentication frame, and a disassociation frame.

Abstract: An example of controlling a network of wireless access points (APs) to detect that a client device associated with the network is stationary in an AP-overlap area, and in response to the detection that the client device is stationary in the AP-overlap area, assigning one of the APs to be a preferred AP for the client device. The APs are to avoid connecting with any client devices that have been assigned another AP as a preferred AP. Thus, the stationary client device in the overlap area may be prevented from undesired roaming.

Abstract: Example implementations of an apparatus may comprise a first processing resource coupled to a second processing resource. The first processing resource may execute instructions to analyze an exception generated from the second processing resource, and identify a bit error on the second processing resource when the analysis of the exception indicates that the exception relates to the bit error on the second processing resource.

Abstract: In implementations of the present disclosure, there is provided an approach for transmitting multicast frames. A method comprises obtaining a multicast frame in a wireless local area network (WLAN), where the WLAN includes a plurality of sub-networks with a same service set identifier (SSID). Then, a target sub-network of the plurality of sub-networks for receiving the multicast frame is determined based on the multicast frame and a unique group temporal key (GTK) for the target sub-network is obtained based on the target sub-network. Next, the multicast frame is encrypted using the obtained unique GTK for the target sub-network, and the encrypted multicast frame is transmitted to one or more client devices in the target sub-network. Implementations of the present disclosure can help the AP to reduce leakage of multicast frames to all client device by using the GTK corresponding the target sub-network.

Abstract: Implementations of the present disclosure relate to packet capture for a multi-link device. In the implementations, an access point (AP) obtains a media access control (MAC) address of a multi-link device (MLD) to be monitored. Further, the AP determines a plurality of links of the MLD to be monitored based on the MAC address. Based on the MAC address of the MLD, the AP captures packets transmitted by the AP MLD on the plurality of links, as a monitor AP. For each of the captured packets, the AP inserts the MAC address of the MLD into an MLD MAC field in a packet capture headroom associated with the packet. In this way, the present disclosure can support flexible packet capture (PCAP) for a specific MLD instead of for a specific link.

Abstract: Systems, methods, and computer readable mediums for persistent TWT sessions include establishing, by an access point, a plurality of sessions with a plurality of stations, wherein one or more of the plurality of sessions comprise a target wake time (TWT), determining, by the access point, that a downtime event will occur before a TWT of a particular station of the plurality of stations, in response to the downtime event occurring during the TWT of the particular station, sending, by the access point, information associated with the plurality of sessions to a secondary device, after the downtime event, retrieving, by the access point, the information associated with the plurality of sessions from the secondary device, and reestablishing, by the access point using the information, the plurality of sessions.

Abstract: Systems and techniques are described that are directed to intelligent scheduling of Wi-Fi services for applications, including enhanced dynamic prioritization. A device, such as an access point (AP), can receive data packets from multiple connected devices to dynamically identify an application flow for each data packet, and dynamically identify a user associated with the application flow for each data packet. The AP can generate prioritized candidate lists for selected data packets in queues corresponding to an access category (AC). In response to determining that the identified user associated with the application flow corresponds with a critical user, the AP can select data packets for the prioritized candidate lists based at least in part on priority policies for each of a plurality of applications and based at least in part on dynamic prioritization of applications for each of a plurality of applications; and schedule data packets from the prioritized candidate lists.

Abstract: Systems and methods are provided for adaptively enabling and disabling spatial reuse and adapting BSS color assignments based on various factors associated with a wireless network. A first AP in a wireless network can identify a second AP in a wireless network. The first AP and the second AP may be using the same wireless channel in the wireless network. The first AP can determine a signal strength, such as a received signal strength indicator (RSSI), associated with the second AP. The first AP can adapt its spatial reuse and BSS color assignment according to the signal strength and a signal strength threshold. By adaptively enabling and disabling spatial reuse and adapting BSS color assignments, the disclosed systems and methods provide for improved reuse of wireless mediums while avoiding collisions.
