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.
Claims18
A node comprising:
- a electronic device and a memory for storing identification related information of the node, said electronic device configured to:
- receive a first signal, the first signal including information used to align a response signal from the node;
- randomly generate information within said node and store said randomly generated information in the memory of the node;
- send the response signal from the node, wherein said response signal conveys the randomly generated information;
- receive a second signal, wherein a portion of the second signal is derived from the randomly generated information conveyed in the response signal;
- said second signal enabling sending of a subsequent-response signal that uniquely identifies the node;
- determine whether the second signal contains information which matches the randomly generated information stored in said memory of the node;
- send the subsequent-response signal which comprises a packet that includes identification related information of the node, said subsequent-response signal from the node being sent only if the portion of the second signal matches the randomly generated information that is stored in the node;
- wherein the first signal, the response signal, the second signal and the subsequent-response signal occur on a common frequency channel;
- and
- wherein the node is capable of receiving subsequent information relating to variable frame boundaries.

A method of communicating, the method comprising:
- receiving a first signal, the first signal including information used to align a response signal from a node;
- randomly generate information within said node and store said randomly generated information in memory within the node;
- sending the response signal from the node, wherein said response signal conveys the randomly generated information;
- receiving a second signal, wherein a portion of the second signal is derived from the randomly generated information conveyed in the response signal;
- said second signal enabling sending of a subsequent-response signal that uniquely identifies the node;
- determining whether the second signal contains information which matches the randomly generated information stored in said memory of the node;
- sending the subsequent-response signal which comprises a packet which includes identification related information of the node, said subsequent-response signal from the node being sent only if the portion of the second signal matches the randomly generated information that is stored in the node;
- and
- wherein the first signal, the response signal, the second signal and the subsequent-response signal occur on a common frequency channel;
- and
- wherein the node is capable of receiving subsequent information relating to variable frame boundaries.
