It seems that most people only read the first 2 paragraphs, then came here to comment about something other than the subject of the article.
The article is about the communication between your electricity meter and the supply authority. It has NOTHING to do about internet. This is technology for your meter to automatically send the usage upstream to the supply authority. Which is why I also agree that it has nothing to do with ICASA except if it interferes with other signals. (A long wire can become a very good antenna)
Surely you know it's compulsory to NOT read an article before you comment on it? And the stronger your opinion on the *heading*, the least you should know about the subject.
The first paragraphs made a distinction between PLC and PLT but that, on its own, would have lost most of the people commenting above. Not that they read it.
Back on topic: We urgently need to get a smart grid system implemented and if we don't use international standards, it'll be ICASA-II with South Africa using systems not implemented anywhere else in the world.
In terms of broadband over power lines, someone at Eskom told me years ago, they can (or did) embed a fibre in the core of the high-voltage line. It always made sense to me to do it this way. Your national grid automatically becomes a fibre grid. Wonder if this ever went anywhere?
