I can just imagine the fun if people started picking up next door's home
movies on their TV.

Next door is usually on a different phase.

What happens if people uses a computer network system over their mains,
won't the two get confused?


I know someone who uses a mains network system to connect 4 computers
and their security system, it works well and I must admit I have been
tempted myself, but I don;t like the idea of 240volts going to a box
that is connected to my Ethernet port.

I wonder if there will be a "phone home" capability built in. Coming
soon TVs with their own spyware/viruses..


That is scary, but at least it can be stopped, after all to phone home
they either need to connect to a phone line or use some sort of internet
service. I suppose it could look for a wireless network and use that,
but then my is encrypted.


I think I will get a T.V this year and put it in storage, until my other
one break down. that will solve the problem in getting a CRT set and
also not having it spy on me.

You computer is battery powered, then?

So long as they both use the same standard (and I believe there's only
one in common use) they should coexist happily, except that all devices
will be contending for use of the powerline.

But you've got 240V going to your monitor, which is attached to your
computer, for example.

Should the worst happen, a twisted pair ethernet adapter ought to cope
with being attached to the mains better than just about any other port
on the computer, by virtue of it being transformer isolated. I know
people in the US have tested them with 120V AC (common mode).

Not really, but there is a box between my motherboard that cuts down the
voltage to a level my motherboard can cope wit.
Using a box that have 240volts going into it that is plugged into my
network port is not my idea of fun.
Most power supplies if they have a fault then it blows an internal fuse
and most of the time the motherboard is protected, I wonder if these
mains network boxes got the same protection?

As I said it seems a good idea and I have seen it working, just a bit
nervous about them

Hello,

you should better not try to receive any radio broadcasts on
medium or shortwave bands near such devices - no chance...

But what happens when/if other standards come out?

A bit different, normally if anything happens it stops at the monitor.

still a bit iffy, anyway would you really want things in your house
connected up to the net?

Mind you saying that, I watched Click a few weeks back and they was
showing a house in Korea, some of the features looked nice, but I would
be worried about my privacy.

then I would have problems, as I do listen to AM radio stations.
