For those interested, I now have PDFs available of five articles that
appeared in the 2003 May issue of "IEEE Communications
Magazine" on broadband over power line. The articles are:
1. Guest editorial
2. Physical and regulatory constraints for communication over the power supply
grid.
3. Coding and modulation for a horrible channel.
4. Advanced signal processing for power line communications.
5. Demonstration of the technical viability of PLC systems on medium- and
low-voltage lines in the US.
6. Broadband PLC access systems and field deployment in European power line
networks.
Only the second article discusses radio interference issues to any degree;
articles (1) and (3) making passing reference but RFI
issues are clearly not in the forefront of the engineering decisions in
choosing coding/modulation techniques. The technical
discussions in (4) through (6) ignore the issue altogether except to consider
interference between adjacent BPL systems.
The tenor of the articles is consistent with other observations: the
proponents of BPL are not aware of the potential damage
their systems will do to other uses of the radio spectrum.
