Mesh Networking For Mobile Machinery (e.g. Construction, Mining)
  Outdoor Industrial Machinery require a private and secure high capacity wireless network. In most cases both IP video surveillance and machine communications data must be delivered across many wireless hops. The machines may be mobile and may need to be part of a dynamic mobile mesh network.
 
Meshdynamics' unique field tested mobility meshing capabilities keep machinery and operators connected at all times. Extensive customer supervised field tests confirmed glitch free video and data transmission between vehicles moving at high speeds. Robust transmission from vehicles moving at high speeds to stationary relay nodes has also been demonstrated. [See Mobility Tests, under related links below]

The stationary nodes may be stand alone, as shown above, powered by battery and solar panels. The network is formed within minutes of powering up the nodes. The mobile units may be taken down at the end of the activity and transported to the next construction or excavation site.  
   
Traditional earlier generation wireless mesh networks perform poorly in this demanding dynamic multi-hop environment. But the MD4000 third-generation network offers high performance for these dynamic mobile mesh applications. Examples include mesh enabled vehicles in surface and underground mining, military and border security.  

Since 2005, Mobile meshed units operate along the Arizona Mexico border as part of a DHS sponsored program. In 2008, vehicle mounted nodes in armored vehicles provided connectivity within mobile convoys in combat environments in Iraq. From 2005 to present, Meshdynamics customers participate in multiple US and Canadian military programs.
