Single frequency data network
A Next Generation Data Network is described. It leverages the “cloud” for data management, frequency data computation and analytics. Packets are transmitted at times and in directions to minimize interference between nodes in the network. The wireless network is a single frequency network that permits limited non-line-of-sight operation.

3. The method of claim 2 , wherein the wireless interference includes interference between two or more nodes.
4. The method of claim 3 , wherein ordering the transmission of the particular packet includes ordering the transmission of the particular packet so that when a transmit beam of the at least one node is pointed in a direction that would cause interference with a receive beam of nodes other than a desired destination node, the receive beam of these nodes are pointed away from the transmit beam.
5. The method of claim 1 , wherein wireless network operates on a single frequency band.
6. The method of claim 1 , wherein wireless network operates on two separate frequencies, and wherein each frequency forms a separate and distinct wireless mesh network.

determine, based on the RF map, that the transmission of the particular packet from at least one node in the particular route will cause interference with the transmission of other packets; and
order the transmission of the particular packet from the distribution node relative to the other packets to mitigate interferences of the wireless transmission of the particular packet from the at least one node with the wireless transmission of other packets.
12. The system of claim 11 , wherein the wireless interference includes interference between two or more nodes.
13. The system of claim 12 , wherein ordering the transmission of the particular packet includes ordering the transmission of the particular packet so that when a transmit beam of the at least one node is pointed in a direction that would cause interference with a receive beam of nodes other than a desired destination node, the receive beam of these nodes are pointed away from the transmit beam.
