1. Tree Based Multi-Radio Mesh Architectures Scale.

The Two Radio, (Uplink and Downlink) Backhaul, mitigates RF interference using non-interfering channel assignments.
2. Conventional Single Channel Backhauls Cannot Scale

This inability - to simultaneously transmit and receive - is a serious disadvantage. If a node cannot send and receive at the same time, it loses ½ of its bandwidth as it attempts to relay packets up and down the backhaul path. A loss of ½ with each hop implies that after 4 hops, a user would be left with (½*½*½*½) = 1/16 of the bandwidth available at the Ethernet link: 1/(2H) relationship defines the fraction of the bandwidth available to a user after H hops, see Figure 2.

3. Embedded Machine Controllers For Local Control Loops

Machine controller applications ("apps"), running on the mesh nodes, monitor and control enterprise assets at the network edge. M2M messaging is latency and jitter aware. A low latency Pub/Sub messaging framework manages periodic packet shuttle services. Performance is analyzed in the cloud. We assume intermittent, unreliable, cloud connectivity. More
