[Swprograms] BBC Click Online - Home Network on electricity wires

[Mike Barraclough <softbulletin1@xxxxxxxxx>]

BBC Click online this week has a report on home
networking on
electricity wires and the radio interference it causes
by Spencer
Kelly

"...It almost sounds too good to be true.

But there is a downside, as technology expert Barry
Fox reveals.

"It sounds like a great idea, to send data into the
home on power
lines. The problem is radio interference.

"When you've got high frequencies going through wires
that aren't
shielded then those wires act an antenna because the
carrier waves -
the waves they're having to send down the power lines
- are in the
same frequency band used by short wave radio."

That means that using the mains as a home network
could interfere with
your enjoyment of shortwave radio, which is used by
lots of
broadcasters around the world, including the BBC World
Service, and
air traffic control. "

Video for both narrowband and broadband users is
available. The
programme is available until 1800 UK time Friday.

The 6 minute report starts 12 minutes 20 seconds into
the programme.
