The FCC proposed new rules aimed at promoting broadband over power lines (BPL). Specifically, the new rules would:
- require BPL devices to employ adaptive interference mitigation techniques to prevent harmful interference to existing users, such as public safety and amateur radio operators. These techniques would enable BPL devices to cease operations altogether, dynamically reduce transmit power, and/or avoid operating on specific frequencies to prevent harmful interference;
- develop a public database that would include such information as location, operational frequencies, and modulation type of BPL devices, which will facilitate the resolution of interference issues in a timely fashion;
- seek comment on specific RF measurement guidelines for BPL devices and other carrier current systems. These guidelines will ensure that emission measurements for these systems are made in a consistent manner. While the Notice addresses RF measurement guidelines, it does not propose any changes to existing applicable emission limits.
The FCC expects the new rules will facilitate the ability of electric utilities to enter the market for broadband services. The technical changes would also help to dynamically manage the power grid itself, increasing network reliability. http://www.fcc.gov
