In America, the FCC has approved rules to regulate the deployment of PLT, or
Broadband over Power Line (BPL) technology, as it is called there. A report
http://www.arrl.org/news/stories/2004/10/14/1/?nc=1 on the ARRL website
says that the FCC adopted a 'Report and Order' when it met on 14 October,
despite the fact that three members of the Commission, including Chairman
Michael K Powell, specifically mentioned the concerns of radio amateurs.
They expressed either assurances or hope that the new BPL rules will
adequately address interference to licensed services.

ARRL President Jim Haynie, W5JBP, said he was encouraged to see the
Commission's shift from the early days of the BPL proceeding, when it
followed the lead of the BPL industry in largely ignoring interference to
amateurs as a real issue. He cited the FCC's approval of three major points
that the League had been pushing for - including mechanisms to deal swiftly
with interference complaints. Full details are on the ARRL website
