Hello all,
Do NOT use powerline network adapters!
They create an awful lot of radio interference. In the range from 2
to 87 MHz they radiate 10000 times more interference than any other
device is allowed to.
So, the warning is because hey are a health issue or because they
interfere with other technical equipment?
Because they cause interference. Which can include interfering with other
users of similar items in homes nearby.
As time has passed, what is allowed in terms of 'powerline' output has been
extended for commercial reasons. Add this to the fact that home mains
wiring is *not* designed for carrying wideband RF, and many mains-powered
devices present a nonlinear load, and you will get problems. Matter of luck
and circumstances, but when throwing dice a few million times you will
sometimes get the result you didn't want.
However people may often get a problem without realising the cause. So this
can occur without people being able to diagose it and assess the scope.
Thus they won't report it, either.
Frankly, the way they were permitted is an example of the way OfCom now
works on the basis that "money talks to lawyers" rather than RF being
assessed by engineers. It relies on those who are adversely affected not
knowing why it happened. So, "few complaints" is take to equal "few
problems".
