BroadBand through Power Lines

`Broadband via power lines soon'

Bangalore , Oct 7

ELECTRICITY lines might soon bring broadband into your premise. At the Intel Developer Forum, a two-day event held at Bangalore, Intel announced that trials were being held to test this concept in India.

Power lines can be used to transfer data with "speeds up to 200 mega bits per second (MBPS) for audio/video and 85 MBPS for data," according to Mr Donald MacDonald, Vice-President of Intel Communication, who spoke on `Enabling the digital lifestyle'.

Intel is part of the HomePlug Alliance, a US-based consortium of technology companies that has been working on this concept since 10 years. The alliance has developed an industry-standard specification for broadband-over-power line, which enables devices to be connected to each other and to the Internet within a home premise, using the electricity wiring.

According to Intel, this concept can similarly be used to provide homes with a broadband connection using their existing power line. Previously, implementation difficulties such as excess of electric noise posed hurdles until now, but have now been solved, said Mr MacDonald. The Artical

I've seen this concept being mentioned on nzherald website about 6 months ago.

Great idea if the power doesn't keep going down!

We get a power cut most days, but we can carry on working with a UPS.

If we had internet through the power lines it would be soooo unreliable!

How is this possible???? Science is a weird b*****d!

Broadband over power lines has been a failure out here in North America. Has been available for the last 2-3 years in select areas but the speeds have been slow and there have been tons of complaints from HAM operators whose reception gets adversely affected by this technology.

When I was in school in Switzerland my dorm used this concept to provide broadband to the rooms without having to rewire - just plug a specially made box into the electric outlet. The speeds were alright, though could have been much better. AFAIK, the tech we used only worked had a range of maybe 100 metres or so, so only practical inside the building. Another building would have required another hub.

The big problem in the past has been transformers. The step down transformers the power companies use won’t let the data pass through them. Wonder how their getting around this problem?

It's an old idea in India they've been talking about it for about three years but it never seems to get off the ground!!
Anyway fibre optic telephone lines are the way to go, tests recently achieved speeds off 111 GB per second!!!!
Speeds of 12Gb may be commercialy available in the next 5-7 years, wow two DVDs in a second, on a perfect connection of course!!

In sweden ,internet via power lines is just a failure. Best way is still to put more investment in telecom infrastructure.

somehow, I envision people being electrocuted at the keyboard if this is ever launched in India.

...you mean if word gets around that you don't need a PC? That just a cheap keyboard will do if you plug it into the mains?

John, it may be that the power and data functions don't rely on each other. The data fumction might even be better in the absense of power!

I remember, long ago, the idea of transmiting music from your hifi to any other room in the house via the mains... I don't think mains-networking is a new idea.

i meant that since almost evey other appliance in india gives the user an electric shock every now and then, i'd be cautious about expecting my computer to differentiate between data and 220V -- especially if they are both coming out of the same socket.

Oh dear, data running up the arm!!!!

A Chennai friend was bemoaning his dead PC. I reached to check the connections and got such a shock from the back of the machine that I told him: if this voltage is running through the case, it is very unlikely the moterboard or anything else inside is still alive .
