摘要： A device, system and method for intelligently dropping frames in a congested wireless network. Video frames from a video encoder may be received and queued in an ordered sequence of outgoing video frames in a transmission queue to be transmitted as data packets by a wireless communication circuit. When network congestion is detected, a relative contextual importance level of an incoming frame received from the video input channel may be compared relative to at least one frame in the transmission queue. The compared frame that has a lower relative contextual importance level may be dropped or omitted from the transmission queue, thereby transmitting data packets of the frames in the transmission queue without the dropped or omitted frames.

摘要： A wireless station (STA) of a wireless network operates to estimate intervals at which to transmit keep-alive messages to an access point (AP) with which the STA is associated. The STA receives a de-authentication frame from the AP. The de-authentication frame indicates that the AP has disassociated the STA due to inactivity. The STA determines a keep-alive interval based on one or more de-authenticated messages, including the de-authentication frame. The STA transmits keep-alive messages according to the determined keep-alive interval.

摘要： A wireless station in a WLAN generates a first set of data elements for sending to a final destination. The wireless station forms a first Internet Protocol (IP) packet with a header portion and a payload portion. The header portion specifies an IP address of a neighbor access point (AP) as the next hop destination. The payload portion of the IP packet includes an IP address of the final destination to indicate that the data elements are to be delivered to the final destination. The wireless station transmits the IP packet to the neighbor AP according to the IP address of the neighbor AP. Extended connectivity based on wireless paths between stations of a wireless local area network (WLAN) is thus provided.

摘要： A wireless node of a wireless network maintains link information for a set of layer-2 addresses, each of the layer-2 addresses corresponding to a medium access control (MAC) address of a corresponding device that transmits packets on the wireless network. The link information indicates whether the corresponding device is in an uplink direction or a downlink direction with respect to the wireless node. The wireless node receives a layer-2 packet in one of the uplink direction and downlink directions, the layer-2 packet containing a layer-2 address specifying a destination system, with no layer-2 address in the layer-2 packet indicating that the packet is destined to the wireless node. The wireless node forwards the layer-2 packet to a next wireless device in one of the uplink direction and downlink direction.

摘要： A first wireless device of a wireless local network is operated in an un-associated data transfer mode at a layer-2 level. In the un-associated data transfer mode, communication between the first wireless device and a second wireless device in the wireless local network is allowed to take place without prior authentication and association between the two wireless devices. The first wireless device participates in formulation of routing information in routing nodes of a wireless mesh network while operating in the un-associated data transfer mode. If configured as an end device, the first wireless device thereafter exchanges data packets with another wireless device in the mesh. If configured as a router, the first wireless device routes packets to corresponding wireless devices in the mesh. Operation in the un-associated data transfer mode may result in reduction in power consumption of nodes in the mesh, as well as increased data throughput.

摘要： An aspect of the present disclosure enables convenient provisioning of multiple wireless devices. In an embodiment, a provisioning agent (e.g., a smart phone) identifies wireless devices requiring provisioning to operate as wireless stations and communicates with each wireless device to provide provisioning parameters for joining a first basic service set (BSS). However, during such communication, the provisioning agent operates as a wireless station and each wireless device operates as an access point (AP) outside of the first BSS. Each wireless device is enabled to be configured according to the received provisioning parameters to thereafter operate as a corresponding wireless station of the first BSS.

摘要： A wireless station of a wireless network generates a single layer-2 frame containing multiple layer-3 packets in its payload. Each of the multiple layer-3 packets is destined to a corresponding different destination. The wireless station transmits the layer-2 frame to an access point (AP) of the wireless network. The AP receives the layer-2 frame, disassembles the payload into individual layer-3 packets, and transmits each of the individual layer-3 packets separately towards the corresponding destinations. In an embodiment, the wireless network is according to IEEE 802.11 standards, each layer-3 packet is an IP packet, and the layer-2 frame is a MAC frame.

摘要： According to an aspect of the present disclosure, an access point sends timing information related to updating of a group key. A wireless station communicates with the access point according to the timing information to receive an updated group key. The updated group key is thereafter used for processing of multicast packets. Due to the use of the timing information, the wireless station can operate in a power-down mode, and yet receive at least the required group keys. In one embodiment, the timing information specifies a future time instance at which the update group may be available. In an alternative embodiment, a version number is associated with each value of the group key and the version number of the currently operative group key (in the access point) is broadcast to the wireless stations.
