4.1.2.3 Influence of signal attenuation and reflection due to branching of the transmission line
Cause:
· Many wiring branches (distribution board, joint box, etc.)
Corrective action example:
· Review the HD-PLC position for less signal attenuation.
· Add multi-hop repeaters
What is the attenuation of transmission power due to branch wiring?

4.1.2.4 HD-PLC network
The PLC network has one Master and it manages the whole, and multiple Terminals that authenticate and
join the network.
When the Master fails, PLC communication cannot be performed. Therefore, when high availability is
required, it is possible to provide a Secondary Master which normally operates as a Terminal and
operates as the Master when the Master fails .
