Re: Internet sevice by electrical recptacal in house.
With both the telephone company and the cable company providing internet service already what would make you think anybody would want to supply it via the electrical service? :roll:
Nobody has ever heard of this and there is nothing specifically in the NEC that would cover it.

Didn't the U.K. already sell us a bridge?

Re: Internet sevice by electrical recptacal in house.
Well, as you see that's really a "beta" test to see if this is really viable.
I don't know what the differences are between power distribution and building wiring in the UK and here (other than there it's 220v 50hz, no center tapped transformer). I do know that this would have to be a carrier current system and at least with our distribution and wiring I would think it would radiate all over the place. The FCC in this country is pretty strict about stuff like that. Cable companies for instance must continually test for radiation, keep records and pay big fines if their fittings are loose, and that's a completely shielded system.
I could be completely wrong on this, but forgetting about technology for the moment I think the red tape and bureaucracy alone in this country would be a major stumbling block.

Re: Internet sevice by electrical recptacal in house.
you guys have already identified most of the major impediments to the utilities getting into this business. the biggest one is probably the head start the cable tv, satellite, and wireless isp's already have on this market.
what is a heck of a lot more interesting is the possibility of expanding plc technology at a LAN level, to carry network, automation, cctv, security, etc. data on a cable plant that already exists in every building. why recable if you can leverage the client's existing wiring investment to do more and better things?
whether anyone jumps on board and gets rich remains to be seen.

There is already POWERLINE local area networking (LAN) for homes and businesses in the U.S.A. Powerline networking can be used to share an Internet connection.
Powerline Networking sources
I suppose you are talking about bringing it in on the drop from the power company?

Re: Internet sevice by electrical recptacal in house.
Carrier current communications has been around for many decades as a means to provide rather simple, low bandwidth communications. Problem is power lines and building wiring are designed to carry power not communications.
Data networking products designed from scratch for the purpose face a constant uphill battle for increased speed so trying to equal or even come close with a transmission medium that was never designed for this is going to have very limited success.
ISDN and DSL (ADSL) are examples (we won't even mention dial up). All adopted regular POTS lines and all face distance/speed limitations. All are surpassed by broadband and fiber which will no doubt leave them in the dust. (Anybody still using ISDN lately?)
Power line networking might be appealing because of the convenience, but technologically there is really no way for it to compete, at least for very long.

Take a look at Article 830. It was added in the 1999 NEC

Re: Internet sevice by electrical recptacal in house.
830 covers network powered broadband communications systems. These are systems that carry on one cable both a broadband signal and power to run the equipment associated with whatever the cable provides. The power can be "diplexed" on the signal carrying conductors or carried by separate conductors within the same jacket.
An example of this that has been around for a long time is the outside CATV plant. The coaxial cable carries the signal as well as 60 volts AC to power the amplifiers along the route.
Normally the broadband signal and not the 60 volts is extended into the building although we have installed line powered amplifiers in buildings that were powered from the outside plant. This situation then would fall under Article 830.
Article 830 has nothing to do with carrier current systems that simply piggy back a signal on an existing power transmission and distribution system. I can't see why the NEC would cover this anyway because it uses a transmission medium that is already in place and well covered already. What more needs to be said?
