Powerline World

Anyone wishing to follow the latest developments in Powerline Technology (broadband down your bog standard electricity cables) can do so at the official news site:

<a href="http://www.ipcf.org" target="_blank">Powerline World</a>

Despite some fall off in this area, many trials are still on-going; particularly in Germany where RWE hope to have their system running by next month. Trials are also currently being run by SSE Telecom in Scotland.

I believe it is still the best (only?) hope for people in small rural communities.

Unfortunately if you want to see any information then you have to become a member, which isn't very helpful since there's little news about the UK.
 
This is true! The forced membership is a bit irritating (but at least it's free) - I suppose it's their way of monitoring the number of people/companies interested. I didn't leave real company info anyway.

Yes, not a lot of UK specific stuff as yet, but I meant it more as a way of following developments in this very new broadband technology. It's still in it's infancy after all. It could be about to make a big impact in Europe though through RWE in Germany. I'm sure more interest from UK companies will follow if it is successful.

Worth keeping an eye on. I think anyway!

The situation in the UK is interesting. About 3 years ago, Nor.Web (a joint venture between Norweb Telecom and Nortel) did some trials of powerline in and around Manchester and it caused so much radio interference that the service was closed down and given up on.

Since then there have been technological developments to reduce the potential to cause interference which might just make the system viable.

However in order to offer internet access to rural communities, it still requires the a feed to be delivered to local electricity sub-stations, which might as well go to the local telephone exchange (where it would more than likely be sourced from anyway) and be delivered using xDSL.

Powerline will never be more than a competitor against cable/DSL and certainly doesn't offer anything special that makes it unique. It is just a means of distributing internet services from a central point (an electricity substation) to homes.
 
Powerline broadband services have recently been ruled out by the Japanese authorities, where extensive trials showed that even with the latest technology they still cause significant interference to HF radio services.

In Europe, a number of administrations have supported the German NB35 standard, but the HF radio users represented in the CEPT are wholly opposed to that, and support a standard that creates no more than a 0.5 decibel increase in background noise, or as a compromise the Norwegian standard, both of which are more than 20 db down on NB35.

The Powerline World website is a joke. I read as far as the section about interference to HF radio services, where it talks about negotiating to offer radio hams "a new frequency", which was enought to show that the site is just marketing fluff. Of course the frequency allocations for hams, aeronautical, marine, land mobile, military, radio astronomy, broadcasting and other services that use the HF spectrum are agreed internationally by the ITU, so it is laughable to suggest that Powerline World has any standing to negotiate anything with any of these users.
