Connect PCs and share printers through your electrical outlets.

Share files, Share Internet Access, and Play Multi-Player Games.

The PassPort Plug-In Network lets you connect PCs and printers using
ordinary electrical outlets. Simply connect the parallel cabels from
your PC or printer to your PassPort Plug-In adapter, plug into any
electrical outlet in your home or office, and you're ready to share an
Internet account, a printer, files or multi-user games between PCs.

You know, its theoretically possible to do what you are saying, but
the fact that you spam to spread the message makes me think you are
a lying slimeball trying to take people's hard earned money.

How in the world can you send digital signals over 110VAC without frying
something??

I'm sure their adapter doesn't pass the voltage. I think the bigger question
is why would anyone want to use this? Hubs, network cards, and CAT5 cable is
cheap (you could easily hook up four computers for under 200 bucks). This
solution would cost upwards of $500 (and run over the LPT port)! Hmmm... I
think I'd rather run the cable and get the SPEED of a real network :) As far
as ease of use -- aside from inserting the network cards in the PC slots -- I
don't see this as particularly "easier" than conventional networking on today's
operating systems. I'd also be leary of routing issues with this solution...

This works by converting your computer's signals to a radio signal, sending it
through the electrical wiring, then converting it back for the other
computer(s) to read.

Whoever sent that, you're absolutely right! Besides, most electronic devices
in the home (including radios, alarm clocks, televisions, etc.) don't like
radio-frequency signals on the power line. How would your family/co-workers
like it if every time you printed something or sent something over the
network, the tvs, radios, and whatever else, picked up a load of static?

There have been other devices in the past which use this concept, such as
whole-house lighting controls (using one or more "master consoles") and
security systems, but these generally don't cause problems because the signal
is sent as a brief pulse, or only when an alarm is triggered.

Probably by using 60Hz notch filters and optical isolators.

I believe the technology is similiar to X-10. A specification for
controlling appliances by using your existing house wiring as a medium. The
network adapters appearing on the market using this technology can maybe
handle 1-2 Mbps at best while a cheapo NIC ($20-$25) can do 10Mbps

I wouldn't waste my money on it.

Absolutely, but consider that it is emerging technology and the extension of
the concept could be VERY interesting. Consider WAN on existing, free
cables. As the technology matures (if it doesn't die in the maturing), the
price will begin to challenge existing solutions. It's worth keeping an eye
on. It's been suggested & touted for years, this bunch is the first to
provide a solution of some kind.

It's also been done for telephones. I actually had a set once. THe reception
was horrible, and the system had a limited range; the other phone had to be
plugged in to an outlet on the same circuit in order for the signal quality
to be usably good (of course, this was many moons ago, and the technology may
have improved)

This idea has been around for many years. A company called Vortec (I
think) used to do a small office network based on it. In the UK one of
the main electricity utilities is offering internet connectivity via the
electrical mains (240v and higher through substations). I would be very
surprised if the full mains voltage goes into the back of the PC. I
guess a little black box goes into a wall outlet to extract the data
signal from the mains and feeds a much lower voltage signal back to the
PC.

The big difficulty I see with this is that the current hardware costs about
twice as much as hardware for a network with 300 times the performance, or
about 5 times as much as for a network with 30 times the performance. So
who is going to buy it?

I'm guessing people who want to have a network without cutting open the
walls in their place, or who don't want cables strung across the floor.

Well, networking via mains hasn't really caught on much has it? Your
point is proven by the idea's lack of widespread commercial success.

I suppose its main selling point was "cheap and cheerful do it yourself
networking" - you plug into a parallel port and no need to open up PCs
and worry about IRQs, Port addresses, card installation, and no need to
invest in expensive network infrastructure, support and consultancy.

Going back to the internet access via mains, and working from memory,
the speed offered is well above modems and ISDN. I haven't heard much
about it for a while though. Perhaps its failed. Anyone know?

No, it's not. You can't get significant bandwidth without severe
adverse consequences. For example, the quality of your television
picture will deteriorate markedly.

Signaling over power lines is not a new technology -- it's been around
for at least twenty years. This is a niche product for installations
which absolutely cannot run additional wiring between rooms and whose
bandwidth needs are modest.

I can see how it'd be possible to filter
out the 60Hz 110V AC to ground? IS it really
this slow though? I'd assume all the PC;s
involved have to be on the same circuit breaker
correct (thus on the same circuit)?
I've noticed most telephone jacks seem
to have unused wiring pairs, could these be
used as 10baset?

I'am not an expert on the subject, just quoting the specs I've seen on some
of these units. All the breakers in an electrical panel branch from the
main power line coming in so it really shouldn't matter what circuit the
network adapter is plugged into. This also means that the network signal
could also travel to surrounding homes. But again, all I really know is
that these systems are a lot slower compared to a cheap Ethernet card.

I don't see why not if you have enough wires around but I personally
wouldn't do it this way.

Yes. The old DOS magazine PC Novice had an article on exactly how to
do it, step-by-step... maybe back in '93 or '94

Well, if you are willing to open up your machines but still don't want to run
wires then I suggest looking at HomeFree from Diamond MM (see
http://www.diamondmm.com/homefree). For $199 you get one PCI and one ISA card
(for $229 you can get a PCMCIA card and an ISA card) and it's totally wireless.
It's not as fast as wired Ethernet, but I think it will meet my requirements
(which is basically sharing peripherals). Here's a brief blurb from their web
site:

one of the electricity companies in the UK did a trial recently where they
put a carrier wave on top of the 240vac electricity supply. The idea was
that equipment at each substation would pick up signals from machines in its
area and forward them on to the rest of the network. Cheap internet access
etc. Unfortunately a side effect of this was radio interference from things
like streetlights (about the right size to act as aerials).. I think the
spec was basically a 1 or 2 mbit/sec lan speed type thing. Not really worth
the effort - buy a cheap ethrnet card.

As I said (below and in the original append), IF YOU ARE WILLING TO OPEN UP YOUR
MACHINES. I am willing to (heck, I have an extra 32mb to install in my kids new
machine that I haven't gotten around to doing). In exchange for doing this you get a
network that is 3 times faster, $50 cheaper, probably more reliable, what else have I
missed?
