Abstract:
1. A communications system, comprising: first and second Time Division Multiple Access (TDMA) mesh networks, each comprising a plurality of wireless nodes; each node of the plurality of wireless nodes within respective first and second TDMA mesh networks comprising a transmitter and receiver that communicate on a primary and at least one secondary frequency and use a TDMA epoch that is divided into at least a beacon interval using the primary frequency and a digital data interval using both the primary and secondary frequencies, wherein the wireless nodes in first and second TDMA mesh networks are synchronized to each other such that a start of TDMA epoch in the first TDMA mesh network overlaps with the start of a TDMA epoch in the second TDMA network and each have the same TDMA epoch duration or an integer multiple thereof and an unused digital data secondary frequency TDMA usage for the second TDMA mesh network falls into an unused portion of the secondary frequency usage map of the first TDMA mesh network.
