The California Public Utilities Commission this week gave a boost to the idea of delivering broadband access over power lines by passing rules allowing trials to take place across the state. Though broadband over power lines (BPL) is a wonderful idea in theory, in practice it has been difficult to implement well. Has its time finally come?

I can only hope for a significant price drop or am I just dreaming?

i've said it once and i'll say it again. internet over power lines (or any net, for that matter) is stupid, stupid, stupid.

the frequency ranges impinged on by this are huge. the signal spreads from the untwisted, non-paired transmission lines like from a ginormous antenna. ham radio, commercial and emergency services, air traffic control are all in the frequency band usually affected.

in austria a provider using internet via powerline has been warned to cease all interference. any further reports of interference will result in fines.


while the idea sounds good in principle and may be feasible technically, the problem that the lines used for transmission are not in the least bit designed to not broadcast the signal transmitted on them makes it impossible to operate problem free.

yeah, well . . .call me a dreamer!

Maybe, the most exciting thing about the technology is not its speed, but the ease with which an alternative nationwide broadband delivery system could be created. This possibility is certainly on the minds of the members of the California Public Utilities Commission, which said in a statement:

"BPL has the potential to bring broadband Internet services to communities who do not have broadband service available today from the telephone companies or cable companies. In fact, in other communities that already have DSL and cable modem service BPL can provide a third broadband 'pipe' to customers, thereby increasing competition and consumer choice," said PUC President Michael R. Peevey.

gee golly. i never would have thought that someone from the public utilities commission would be pushing that product.  Laughing

i'm sure that as soon as they go operational and the emergency services can't use their radios anymore (along with the ham operators) he will be educated on stray transmissions.

Maybe an alternative to at least let the others know that they are not the only ones in the game.  ;)
Could have at least a little effect on the price of the others.  Very Happy

Competition is always good.  ;)

yes competition is good and all that. but do you want to get that competition at the cost of jamming a broad spectrum? besides, the areas in question only have power and phone lines to them, the phone lines are too long for dsl and there is no cable because it is just not worth laying cable there. so powerline would be the only option.

I just dont think people in general would be real crazy about hooking up there computer knowing that the service is comming any where near a power line. Even if it was explaned I still think most would want to avoid it.

that sounds remarkably useful. since you have the gas pipes going all over the damned place anyway (in those places that get supplied with gas of course) they offer a great way to lay some fiber/tp/coax without having to dig everything up. simply use existing maintenance/inspection openings to shoot in the fiber. Brilliant!

(and even if there is a spark there's no danger of a fire. they are gas lines not gas/air mixture lines.)

Hi Reso. yeah the UK has got good gas supply, and it woull save the usual chaos of digging up the roads, yeah I appreciate the the no explosion part
It just made everyone laugh in the UK, but technically a brilliant Idea,
especially for me, as I am limited to 1Mb dsl, due to distance from tel co (BT)
I am on the amazing 256/128 Kb for the time being,  angry2

That is me.  Very Happy
That is why I have satelite.
Might be a cost effective alternative.
I wonder what the speeds and monthly $ would be.

some good info on powerline.

http://glasnost.itcarlow.ie/~net4/kirwans/bband.html


note the allowable radio interference under side effects.

attached an australian study on powerline systems.

depends on how many people on one trunk. they have 54 mbit, so anything over 50 users on a trunk gets slowed down below 1 mbit down, but the pings should be better.


there is no justification however for jamming the airwaves.

Good info resopalrabotnick, thanks.
A couple of good things. Voip,internet, and T.V.

It is hoped it will be possible to have devices such as home entertainment systems and other household appliances will also be placed on this data network and allow services such as viewing streamed media and web browsing from televisions. It is hoped that services such as VOIP will be offered allowing this technology to compete not only with ISPs but also with existing Telco?s.

Out in the country where I am, I only share with one neighbor on my transformer.(assuming that is where the modem goes). Further reading states that it is dependant upon the users of the sub-station. I hope they do not go for the wifi setup!

So substation, 45Mbps / 50 users,(only if all use) could actually get full 45Mbps at a slow time. WOW.
And not everybody D/L's at the same time. Hmm interesting.
Not sure about the 200 Mbps of the Opera Goals?

And no 45,000 mile jet lag!  Very Happy
Look out Dway, you better straighten up! Laughing
