[OT]Question on X10 devices

Sorry, I mistakingly used the phrase "high frequency".

but X10's frequency is always like 60Hz or 120 because it only appears on zero crossing edges.

very slow speed communication system, I think this is probably a better system compared to CAN bus or LIN

on the second link looks pretty complicated because it must meet some industrial standards. For
personnel interest, I wonder if someone may show me some similar but simple way on transmitting some high
frequency 
 "glitches" as digital data via small AC or DC power lines?> > > >
