Abstract: A communication system is provided that enables a node to be identified by a controller. To establish a communication link from the node an alignment signal is received from the controller. Upon receiving the controller alignment information, the node sends a response including information the node randomly generated. The controller then responds by sending back at least a portion of the information the node randomly generated indicating that the node has been recognized by the controller.
Abstract: A communication system is provided that includes a controller and a system to allow efficient transmission of information with a plurality of nodes. The information includes an alignment signal provided from the controller to enable the nodes to align their response signals. The information further includes node identification information. Once alignment and identification occur, nodes can then transmit packet data to the controller.
