Powerline Ethernet issues cross-phases?

[stevech]

In the US, common home power has two "phases". Historically, X10 which is just 100KHz, has difficulty coupling across the two phases unless you add an X10 signal-specific phase bridge/coupler, usually inside the breaker box. Some electrical code issues doing this.

Do the ethernet powerline devices have the same issue? Of course, the frequencies are much higher, and OFDM, but the attenuation across phases might still be an issue.

The symptom is that if unit A is in an outlet wired to phase A, then the signal at outlets on phase B are much weaker. This might yield lower data rates or reliability issues.

I've been using MoCA (IP over coax) - but that works only if the coax is where you need it to be!

HP-AV doesn't have any problem with split phase wiring.
Give it a try.

I wonder why? There's no decent signal path, and X10 PLC is famous for needed an added phase bridge.

HomePlug has not had a problem with working across phases for a few generations now. It uses both conducted and radiated signals.
