"Sustainable, Future-Proof, Industrial Mesh Networks"
MeshDynamics has been talking about our multi-radio multi-channel wireless mesh
networks since 2002 but there is confusion about what "multi-radio" means,
and why MeshDynamics' patented tree-based framework sets us apart. Three take
Channel Backhauls Cannot Scale
Fig.1 Competing mesh products suffer from ½ Bandwidth loss with each
hop, and more delay (latency) with each hop.
The inability of single radio backhauls 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 throughput and
real time response after 4 hops,

Fact: Multi-Radio Tree Based Mesh Architectures Scale.

scalable, frequency-agile, network performance.
Our nodes connect as logical branches of a tree. As in Nature, a tree based
routing is scalable, efficient and deterministic. Tree based networks are also
inherently secure and self healing. The loss/corruption of a branch, does not
cripple the entire network. Further, the routing overhead is
, not O(N*N).
Performance degradation is tangible
as industrial networks grow.
Feature: Onboard Intelligence Orchestrates Local Events

Our mesh nodes manage branches of the wireless network "tree". A distributed
control system, running on each node, manages the health of the entire network
and its assets. Enterprise "apps" running on the mesh nodes, communicate through
periodic "heart beats". Real time sensor streams are transported to relevant
subscribers and machine controller apps on the mesh node serve as proxies when
cloud connections are lost - disruption tolerant
