Should it proceed, this technology may well see the end of many radio services that use spectrum between 2 and 30MHz. That is because current versions of this technology pollute the radio spectrum, and creates so much interference that almost all cuurent users will not be able to operate. Future developments may change this problem, but current trials have proven beyond any doubt that current technology behaves this way.

Potential Operators (for example power utilities) seem to be ignoring this problem. What they should also consider is that current (legitimate) HF spectrum users will interfer with BPL making data transfer sporadic and painfully intermittent for the end user.

This is definately a case of the wrong technology for the application. Power utilities, please think hard about what you are attempting to do here. The ACMA needs to have a good look at this as allow santity to prevail. There is more at stake than competition and dollars.
