<p>In a wireless packet communication system having a plurality of nodes, each having a transmitter and a receiver, the receiver at each node is assigned a seed value and is provided with a channel punchout mask (s1). A node uses its seed value and punchout mask to generate a specific randomly ordered channel hopping band plan (s3) on which to receive signals. A node transmits its seed value and punchout mask (s1) to target nodes with which it wants to establish communication links, and each of those target nodes uses the seed value and punchout mask to generate the randomly ordered channel hopping band plan (s3) for that node. Subsequently, when one of the target nodes wishes to transmit to the node, the target node changes frequency to the frequency of the node according to that node's band plan (s5).</p> |
