Hello Jim,
Anyone know about Broadband Over Power Lines... inside buildings?
It is commonly called PLC if you want to search Google. In Germany they
rolled it out in some areas and what I heard sounded like rather mixed
blessings. Sustained data rates not that great, lots of EMI issues. The
power grid is not at all a suitable medium for communications. Plug in a
piece of equipment with really good Y-caps and your comms might go
down. Then there is uncle Leroy's blender where he should have changed
the motor brushes a long time ago but never got around to it. That can
look like a hail storm on the analyzer.
Personally I do not believe in this technology. Just MHO.
Given the unreliability of X-10 I find it hard to fathom how it could
work very well.
X10 is IMHO an ill-conceived protocol. I do not understand how an on/off
AM protocol could be adopted on such a noisy channel. On our X10 stuff I
also found that many modules were grossly mis-aligned. Tuning them all
improved things quite a bit but it is not 100% reliable, of course. Then
the controllers also have issues, maybe buggy code. Once in a while they
go on the fritz and you have to power cycle them.
