The power of Distributed,
Dynamic, Radio Intelligence
Mesh Networks need to proactively avoid co-channel interference
from multiple radios
operating in a given frequency band. We allocate channels
dynamically, listening for adjacent nodes as well as
competing, interfering, or jamming sources. Channel maps are
selected and reselected as necessary to provide optimum
performance and to maintain connectivity, no matter how the RF
environment may change nor how individual nodes may move in
relationship to one another.
Meshdynamics automates channel-selection and
topology-definition tasks by distributing dynamic radio
intelligence in each node, in effect creating multiple "RF
robots". Patented algorithms enable all nodes to
periodically SCAN its environment to
determine its relationship with neighboring nodes, alternate
extraneous and potentially
interfering radio sources
Fig.1 Distributed Radio Intelligence at each node, manages
channel interference and tree topology management.
In this distributed dynamic radio intelligence approach, the
network forms a
tree-like structure emanating from one or more "root"
nodes that have the wired or fiber connection to the Internet
or intranet. As the branches of the "tree" radiate outward,
eventually they become geographically distant enough from one
another for nodes to begin re-using channels. This increases the capacity of the network,
making better use of the scarcest resource: the number of non
interfering RF channels available.
The independent but coordinated "RF robots" in nodes are
useful in detecting and avoiding
Nodes close to these RF sources move - in
coordinated fashion - to a less used channel. Impact to end users is minimized.
Meshdynamics is Radio
Frequency (RF) and Communication Protocol Agnostic.
Generation implementation is not limited to any particular number or type of
physical radios, or indeed to the concept of separate physical radios at
all. Instead, the Meshdynamics MeshControlTM
mesh networking algorithm treats physical and/or logical
radios as a pool of available connections to be dynamically
managed for optimum performance.
software (items orange, above) is uniquely radio-manufacturer
independent, allowing the rapid addition of new radio
frequencies, radio suppliers and new technologies. The
MeshControlTM software is
therefore future-proof: it can been upgraded to new RF standards, as they
become proven and commercially feasible.
Decoupling the logical channel-selection and
topology-definition processes from the specific physical
radio in this fashion delivers distributed dynamic radio
intelligence benefits for current as well as emerging radio
An additional benefit of decoupling the distributed dynamic radio intelligence
(e.g. controlling channel selection and topology
configuration) from the radio hardware, is the potential to incorporate
(lower cost) commercial-off-the-shelf (COTS) radios.
This substantially decreases time-to-market and greatly
increases manufacturing scale, reducing both development- and
unit cost over the use of custom hardware development.

software takes Radio
Frequency Agility one step further in our
products. Figure 2 shows how this level of flexibility is leveraged
in the MD4000 4 radio products. There are 4 mini-PCI slots on the board, two on the bottom and two on top. Each of the four slots can house a different frequency radio. This opens up some interesting possibilities including 2.4 GHz backhaul systems being part of a mesh with 5.8 GHz backhauls.

The service and backhaul radios are distinct, and operating in different
domains/channels, it is possible to use a service radio to bridge over from a 5.8 GHz backhaul to 2.4 GHz backhaul,

and potentially disparate radio communication protocols. The logical
