摘要： A wireless mesh network includes mesh APs and a root AP forming a root of a tree of the mesh APs in which the mesh APs are linked back to the root AP over wireless backhaul links. The root AP has a wired connection to a wired network. An AP detects a loss of connectivity to a controller through which traffic associated with the AP is normally routed to and from the wired network. In response, if the AP is the root AP, the root AP operates as a proxy controller through which the traffic may be routed. The AP maintains connectivity with parent and child APs over the wireless backhaul links.

摘要： A channel sounding scheme is presented herein that relies on a combination of a first channel sounding procedure and a second channel sounding procedure. The first channel sounding technique is one that involves an exchange of dedicated channel sounding related signals to determine channel conditions between the first wireless communication device and the particular second wireless communication device. The second channel sounding technique is one in which channel conditions are implicitly discovered from any signals transmitted by the particular second wireless communication device to the first wireless communication device. A first wireless communication device computes updates to steering matrix information used for beamforming one or more signal streams to a particular second wireless communication device based on a combination of the first channel sounding technique and the second channel sounding technique.

摘要： A wireless mesh network includes mesh access points (mesh APs) and a root access point (RAP) forming a root of a tree of the mesh APs in which the mesh APs are linked back to the RAP through parent-child relationships over wireless backhaul links. A mesh AP provides access to the mesh network via connections to wireless clients in one or more wireless local area networks (WLANs) served by the mesh AP. The mesh AP stores mappings between the one or more WLANs served by the mesh AP and one or more virtual local area networks (VLANs) configured on a wired network and to which the WLANs are assigned. The mesh AP receives mappings between the VLANs configured on the wired network and WLANs served by the mesh AP as known by the RAP. If the stored mappings and the received mappings differ, the mesh AP updates the stored mappings with the received mappings that differ from the stored mappings.

摘要： A method is performed at a mesh access point (MAP) in a wireless mesh network including access points (APs) of a spanning tree being divided among multiple Internet Protocol (IP) subnets. The method includes receiving from a first parent AP to which the MAP is a child a first IP subnet identifier indicating the first IP subnet to which the first parent AP belongs. The method also includes obtaining a first IP address associated with the first IP subnet, roaming from the first to a second parent AP, receiving from the second parent AP a second IP subnet identifier indicating a second IP subnet to which the second parent AP belongs, determining if the first and second parent APs are both part of the same IP subnet, and determining whether to maintain connectivity with a current controller or establish connectivity to a new controller based on results of the determining.
