Patent ID: 7894416

Claim:
A system for communicating, comprising: a plurality of wireless nodes configurable to form a first time division multiple access (TDMA) mesh network and a second TDMA mesh network; each wireless node of the plurality of wireless nodes comprising a transmitter, and a receiver, wherein said each wireless node is configured to transmit data packets across said first TDMA mesh network or said second TDMA mesh network from a source node through intermediate neighboring nodes to a destination node on a primary frequency and at least one secondary frequency using a TDMA epoch that is divided into at least a beacon interval using the primary frequency and a digital data interval using the primary frequency and the at least one secondary frequency; said each wireless node configured to overlap frequency usage on the at least one secondary frequency between said first TDMA mesh network and said second TDMA mesh network, wherein a slot of channel time is allocated in both time and in TDMA epoch prior to a wireless node of the plurality of wireless nodes transmitting the data packets; said first TDMA mesh network and said second TDMA mesh network allocate an unused portion of the at least one secondary frequency to the second TDMA mesh network, such that the digital data interval for the second TDMA mesh network does not fall into a used portion of the at least one secondary frequency allocated to the first TDMA mesh network; and said plurality of wireless nodes refigure-out a lowest latency after detecting changes in a route.
