摘要： A wireless access point includes a wireless interface to send or receive frames in a cell in a wireless network. A storage device stores a cell ID that uniquely identifies the wireless access point. Processing circuitry inserts the cell ID in a physical layer header of a frame, and sends the frame to a client device in the cell via the wireless interface.

摘要： In one implementation, a region descriptor associated with a communications access point and a location descriptor are accessed at a client. The client determines that a location described by the location descriptor is included within a region described by the region descriptor. The client then requests association with the communications access point in response to the determining.

摘要： The present disclosure is directed to networks having reduced power consumption characteristics and associated methods. In one aspect, a method for reducing power consumption in a multi-hop network can include receiving data at a plurality of primary nodes in a multi-hop network and transmitting the data from the plurality of primary nodes to a plurality of secondary nodes. Individual primary nodes have nearest neighbors at a defined distance and the secondary nodes are spaced at a distance that is greater than the defined distance away from individual primary nodes. Data is transmitted from a given primary node to a secondary node by skipping at least one intervening node and reducing power consumption of the wireless network.

Packets are received on an m×n×Wi channel configuration, wherein m is the number of receive antennas used to receive the packets, n is the number of transmit antennas used to transmit the packets, and Wi is the number of OFDM channels for a packet i in the MIMO-OFDM system. CSI estimates are generated for the received packets and the CSI estimates are extrapolated to generate a combined CSI estimate for an m×n×R channel configuration, wherein R>Wi.

摘要： A method for extrapolating channel state information (“CSI”) estimates from multiple packets sent over different antennas to generate a combined CSI estimate for a MIMO-OFDM system is disclosed. Packets are received on m×ni×W channel configurations, wherein m is the number of receive antennas used to receive the packets, ni is the number of transmit antennas used to transmit the packet indexed with i, and W is the number of OFDM channels in the MIMO-OFDM system. CSI estimates are generated for the received packets and the CSI estimates are extrapolated to generate a combined CSI estimate for an m×q×W channel configuration, wherein q>ni for all i.

摘要： A node in a multi-hop wireless network includes a master radio and a surrogate radio. The master radio performs data communication on a main multi-hop path in the multi-hop wireless network, and the surrogate radio simultaneously scans one or more channels in the multi-hop wireless network. A channel manager determines if a link between two different nodes on the main multi-hop path is disconnected, and, in response to determining a disconnection of the link between two different nodes on the main multi-hop path, the data communication is switched to an alternative multi-hop path in the multi-hop wireless network based on information obtained from the scanning of the one or more channels.
