雙模特點

  Seamless integration of PLC and sub-GHz communication.

  Best path selection mixing of wired and wireless channels

  L2 hybrid networking with common upper layers

  • Less memory overhead
  • Less delay through the path
  • Applicable to arbitrary upper-layer protocols
  • No modification effort for user applications

  Hop-by-hop selection of RF & PLC (RF-PLC-RF-PLC...)

  • Higher packet success rate than end-to-end approach (RF-RF-...-RF or PLC-PLC-...-PLC)
  • Interoperable with existing PLC nodes
  • Flexible to deploy (partial replacement is possible)

  Backbone for electricity/ gas/ heat/ water AMR
