Abstract:
1. A wireless network comprising: a first wireless mesh network including a first gateway and a first plurality of nodes that transmit and receive messages over synchronized links between pairs of nodes, each link pre-determined by assignment of an RF frequency channel and a communication time slot on a first communication cycle, wherein the combination of the assigned RF frequency channel and communication time slot is not shared with any other link in the first wireless mesh network; and a second wireless mesh network including a second gateway and a second plurality of nodes that transmit and receive messages over synchronized links between pairs of nodes, each link pre-determined by assignment of an RF frequency channel and a communication time slot on a second communication cycle, wherein the combination of the assigned RF frequency channel and communication time slot is not shared with any other link in the second wireless mesh network; wherein the first and second mesh networks at least partially overlap so that at least one common node is a member of both the first plurality of nodes and the second plurality of nodes and communicates with the first gateway through the first wireless mesh network and communicates with the second gateway through the second wireless mesh network.
