Ethernet extender kit claims to send data through power cables - Is this correct?
Engineering Asked on February 8, 2021
I own an ethernet extender kit which has two devices connected to mains. Its data sheet claims that the device "your homes electrical wiring to extend your broadband network anywhere in the house". An informative youtube video also suggests that the data is transferred from your mains.
The little I know about 3 pin power sockets makes me think that this is impossible. I strongly suspect that both devices have receivers and transmitters within them that transmit the data. Is there any way I can prove/disprove this?

Yes. Run an extension lead from your neighbour's house to power one of the devices. It should fail due to either distance or your neighbour being on a different phase of the mains.
