FCC Proposes Rules For Broadband Over Power Lines
Washington, DC - Feb 12, 2004 - The FCC has proposed changes to
certain technical rules with the intent of fostering broadband
deployment by permitting the use of broadband over power lines (BPL).
The FCC considers the nation's power grid to have "significantly
untapped capabilities." The FCC has also stated that it intends to
safeguard existing services against harmful interference.
The Part 15 rule changes, proposed in a Notice of Proposed Rulemaking (NPRM), set forth procedures to measure the radio frequency (RF) energy emitted by equipment used to provide broadband service over power lines and establish particularized interference mitigation requirements. The FCC news release announcing the NPRM has an optimistic view of BPL and states that the FCC' effort "takes an important step toward increasing the availability of broadband in rural and underserved areas because power lines reach virtually every home and community in the country."
The release goes on to say that "in areas in which consumers already have broadband access, BPL enhances competition by providing another broadband alternative. These proposed changes will also facilitate the ability of electric utilities to dynamically manage the power grid itself, increasing network reliability."
The Commission proposes rules requiring BPL devices will use 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 or avoid operating on specific frequencies to prevent harmful interference. The proposal also includes the goal of developing a public database of information with the location, operational frequencies and modulation type of BPL devices, which will facilitate the resolution of interference issues in a timely fashion.
The NPRM also seeks 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 NPRM addresses RF measurement guidelines, it does not propose any changes to existing applicable emission limits.
AES Solicits Technical Papers
San Francisco - Feb 8, 2004 - The AES 117th Convention Committee
invites submission of technical papers for presentation at the 2004
October meeting in San Francisco. A proposed title, 60- to 120-word
abstract, and 500- to 750-word précis of the paper should be
submitted via the Internet to the AES 117th paper-submission site at
www.aes.org/117th_authors by May 17, 2004. For more information and
complete instructions visit the site anytime after Feb. 24, 2004.
The author’s information, title, abstract, précis and choice between lecture or poster presentation should be all submitted online. Titles and abstracts should follow the guidelines in Information for Authors at www.aes.org/journal/con_infoauth.html. Abstracts of accepted papers will be published in the convention program.
The AES asks that writers choose their wording carefully. The précis should describe the work performed, methods employed, conclusion(s) and significance of the paper. All papers with demonstrations must be in lecture sessions. Highly detailed papers are best in poster sessions, which permit greater interaction between author and audience. Poster presentations and lectures have the same review process and preprint requirements; the content will determine which type of presentation works best for author and audience. Writers will be asked to specify a preference when you make your proposal online.
Acceptance of papers will be determined by a review committee based on an assessment of the précis. To present an accepted paper at the convention, an author must submit a preprint manuscript by the Aug. 16, 2004, deadline with content consistent with the précis and with a technical rather than a marketing orientation.
