Product Specifications Key Features
  • Mesh topology
    • unlimited number of hops (relaying steps),
    • only one type of node - no network planning.
  • Multiple, simultaneous signal paths
    • no single point of failure
    • superior handling of obstructions and interferences,
    • robustness and increased range.
  • No-knowledge, no-training installation & maintenance.
  • Instant Addition and Removal of Sensor Nodes – No Downtime of Network.
  • No need to develop network managing software, almost no integration effort.
Architecture
  • The VEmesh network has been designed to work in mesh topology. Its two types of network elements are the Nodes and the Gateway.
  • A VEmesh Node can be a stand alone module or an add-on board that plugs into or otherwise connects to the customer's own board, for add-on wireless mesh network functionality.
  • A single VEmesh Gateway is sufficient to access the entire mesh network from the customer management center.
