MeshedPi - Repeater
Receive the signal, e.g. from one segment, via directed antennas. Process and retransmit the signal, with full power again, towards the direction
where it is needed and has to be received. You can retransmit as omni-directional, to all directions in the same way, just with four times the power compared to a single module.
Or, much better: if your Swarm Network protocol knows where the distination node is located, it can transmit just towards this direction, via directed antenna. In any case, the signal/message is reconstructed, retransmitted with full power and you can extend the distance dramatically.
