RelayNet
TWELITE NET has a LayerTree network as a relay network.
A LayerTree network is a relay network designed for efficient upstream delivery. LayerTree_mininodes, which are solely for transmission, are also part of the LayerTree network.

Basic principles

  • There is only one parent unit and all communication is centralised in the parent unit.
  • As a general rule, the direction of delivery is from the end node to the upper level and finally to the parent machine.
    • Downward delivery from the parent unit is by broadcast communication.
    • Communication between sub-units and repeaters is only possible after delivery to the parent unit.
    • However, it is possible to send directly between nodes that are within radio range by specifying their addresses.
  • The transponder predetermines its own number of levels.
  • Connect to a repeater within radio range that is higher in the hierarchy than your own (the repeater with the lower hierarchy number).
  • By using LayerTree Mininodes, which do not have a destination repeater but only transmit, they can act as sensor nodes with very low battery consumption. (App_Tag)

(YELLOW n) : Child node which can relay. (n represents number of layer)
(Blue) : Child node which can work with sleeping.

About layers

The parent machine is numbered 0 and can number its layers up to 63.
It is OK to skip numbers as long as they are in ascending order.
