Software Driven MeshTM -- Overview

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.  Quick take aways:
-- 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 of its bandwidth as it attempts to relay packets up and down the backhaul path. A loss of with each hop implies that after 4 hops, a user would be left with (***) = 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, More
-- Our nodes connect as logical branches of a tree. As in Nature, a tree based routing is scalable, efficient and deterministic. Trees are inherently self healing.  The loss/corruption of a branch, does not cripple the entire network. Our mesh nodes manage branches of the wireless network "tree", with added features to support mobility, diverse transceivers etc. More

-- A distributed control system, running on each "node", manages health of the network and clients. Nodes and enterprise "apps" running on the mesh nodes, communicate through periodic "heart beats".

-- This heart beat system is also used by applications running on the OpenWRT mesh nodes thus moving intelligence literally to the edge. The application heart beats are topic based and easily integrated into enterprise control systems.

Structured MeshTM: Benefits over non-tree mesh networking architectures.  This paper analyses how with merely 5 simultaneous clients per mesh node, both the single radio ad hoc and the dual-radio, single radio mesh architectures cannot provide usable bandwidth (for voice/video) beyond 2 hops and the implications of these limitations.

MeshControlTM : Radio and Protocol Agnostic Routing Control, Future Proof By Design.
  Scalable software techniques mandate a level of device abstraction. Our Open Source centric approach is intentionally radio & protocol agnostic. This accelerates product development for our OEM source code licensees. More

P3MTM : Persistent 3rd Generation Mobile Connectivity for  military, mining.  Our mobile multi-radio backhaul nodes were set up in a one-mile test course along a public road, simulating a railroad right-of-way. The automobile was driven in repeated passes along the simulated railroad right-of-way at speeds of 55-60 mph. Field Test Reports   and   P3M Manual

Overview of Patent Portfolio Listed Here
"Leaky" pipes are endemic to all forms of wireless communication. Pipe "insulation" is affected by RF interference and involuntary bandwidth sharing. Yet, this pipe is expected to provide equivalent wired performance. 
Seminal work in Oct 2002 depicted how "hop" and "toll" costs - at each node - changes network tree topology to meet diverse application needs. Improvements for real time streams are taught in Managing latency and jitter (2005). Self Forming VOIP (2009) and Mobile and temporal networks  (2010) address mobility extensions. 
Collaborative scheduling  (2012) reduces "collision" in real time. Chirp Networks (2012) and Terse Messaging (2014)  focus on time sensitive messaging for industrial mesh networks.  Evolutionary networks (2018) extends P3M for rapid tree topology reversals for disruption tolerance and mitigating single radio limitations first described as "Ugly Truths" in 2004.
