 MD2000 MD4000 MD6000 Modular MeshTM Architecture  

Our software is OpenWRT and MAC80211 based. It has been ported to multiple platforms e.g X86, Cavium, IMX6.  
The Modular Mesh software supports up to 6 slots/radios, based on the Gateworks Ventana Family:

  Slot 0, &  Slot 1 uplink and downlink form the basic backhaul, operating on 5.8GHz, 4.9GHz or 2.4Ghz bands..
  Slot 2 is generally used for a 2.4G or 4.9G AP (client access) radio.
  Slot 3 may house another AP radio, another downlink or a dedicated scanning radio (mobile nodes) .
  Slot 4+ may house other radios, specific to customer interests e.g. LTE, BLE etc. (MD6000 only) 

Board Configurations: Three popular board configurations are:

  Ventana 5520  - (MD2000). - a two slot board replacement for the one radio MD1000 series 
  Ventana 5530  - (MD4000) - a four slot board replacement for the Legacy MD4000.   
  Ventana 5400  - (MD6000) - Version of MD4000  with two available slots for customer application extensions.

 MD4000 Commonly Used Models and their Applications

  MD4250 is used for remote video surveillance and perimeter security.
  MD4350 is a popular configuration with one 2.4GHz Access Point radio for client service.
  MD4452 MD4454 support two and four backhaul downlinks respectively.
  MD4458 support multiple service radios where high client density is anticipated. It supports 2 or 3 client AP radios.  
  MD4455 MD4355 MD4325 use a scanning radio in slot 3 to ensure rapid switch over from node to node in a mobile setting. 


Bridging Across Multiple Networks.

Meshdynamics mesh nodes can bridge a 2.4 GHz sub tree with the 5.8GHz mesh network tree. The figure above shows how this level of flexibility is supported. 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. Since the service and backhaul radios are distinct, it is possible to use a service radio to bridge over from a 5.8 GHz backhaul to 2.4 GHz backhaul. The 4325 Mobility Relay node on the bottom left has joined the mesh even though the upper links are 5.8 GHz (blue) through the service radio (pink).  See: Radio and Protocol Agnostic Approach
 
Man-wearable Single Radio Modules.

Meshdynamics Interoperable framework supports both multi-radio and single radio modules (shown above). The compact multi-radio units form the core Mobile Mesh Backhaul. Communications at the edge of the network are supported by single radio mesh capable portable units to provide communication and connectivity at the network edge.

GPS Position Location Option. 

See GPS Options. The GPS location information is transmitted periodically with the mesh node heart beat. The mesh node location is automatically updated on the NMS. The NMS uses imported maps and dynamically manages the background image movement to ensure that the current location is correctly depicted.  

P3MTM Persistent Mobile Mesh.

A cluster of mobile nodes automatically form a network with each other. If the cluster physically separates into two smaller clusters, each will then become its own independent network.  If two separate clusters/networks physically come together, one single network will form and all nodes + associated clients will then be able to share data. In a deployed combat environment in Iraq, vehicle-mounted nodes demonstrated reliable connectivity between convoy vehicles in simultaneous motion. Networks split and reformed dynamically and in real time. Applications supported by Meshdynamics systems operated flawlessly as vehicles moved through rugged terrain.

Persistent Base VoiceTM (PBV).

VOIP phones function even when the SIP gateway is not reachable: the mesh nodes act as a temporary proxy SIP server till nodes rejoin the main mesh. This feature has bee replaced by real time publish-subscribe application streams.
