US House Resolution Calls on FCC to Evaluate BPL Interference, Review Rules

ARRL General Counsel Chris Imlay, W3KD, Rep Mike Ross, WD5DVR, and ARRL CEO David Sumner, K1ZZ, met in Ross's Washington office April 26.

NEWINGTON, CT, Apr 28, 2005--Rep Michael Ross, WD5DVR, of Arkansas, has introduced a resolution in the US House of Representatives calling on the FCC to "conduct a full and complete analysis" of radio interference from broadband over power line (BPL). The resolution, H. Res 230, says the Commission should comprehensively evaluate BPL's interference potential incorporating "extensive public review and comment," and--in light of that analysis--to "reconsider and review" its new BPL rules. If approved by the full House, the non-binding resolution, introduced April 21, would express the requests as "the sense of the House of Representatives." The FCC adopted rules to govern so-called Access BPL last October 14 in ET Docket 04-37.

"We are grateful to Congressman Ross and his staff for taking a leadership position in recognizing that the BPL interference issue deserves more careful consideration than the FCC was willing to give it under former Chairman Powell," said ARRL CEO David Sumner, K1ZZ. The resolution has been referred to the House Committee on Energy and Commerce, on which Ross serves.

The resolution's prime focus is on BPL's potential to disrupt critical public safety radiocommunication. It cites National Telecommunications and Information Administration (NTIA) studies that "have determined that broadband over power line creates a 'high risk' of radio wave interference, and that harmful interference to public safety mobile radio receivers can be expected at distances of 75 meters from the power line where broadband over power line is in operation, and at distances of up to 460 meters from fixed stations, such as VHF police or fire dispatch communications facilities."

The resolution notes that the same NTIA study determined that BPL interference to aeronautical and airline travel communications "could be expected at distances up to 40 kilometers from the center of the broadband over power line system, and that interference to outer marker beacons for airline instrument landing systems could be expected at great distances as well."

Many public safety agencies and support services, including emergency medical services, fire, and law enforcement, utilize Low-Band VHF (30-50 MHz), the resolution points out. Thirteen states--California, Connecticut, Florida, Illinois, Indiana, Mississippi, Missouri, Nebraska, North Carolina, South Carolina, Tennessee, West Virginia and Wyoming--use the band for state police operations, while it's the primary public safety radio band in nine states.

The resolution further notes that the Association of Public Safety Communications Officials Inc (APCO), and the National Public Safety Telecommunications Council (NPSTC), urged the FCC to withhold final action in the BPL proceeding for at least a year, pending a "conclusive determination" of BPL's potential to interfere with public safety and other licensed radio systems operating below 80 MHz. APCO and NPSTC jointly filed comments in the BPL proceeding, and the APCO Region 21 Frequency Advisory Committee filed separate comments.

The resolution also sites comments that the FCC has struggled for years to resolve widespread harmful interference to the radiocommunications of first responders on 800 MHz and "should not have proceeded with introduction of a technology which appears to have substantial potential to cause destructive interference to police, fire, emergency medical services, and other public safety radio systems" without first conducting a comprehensive evaluation.

ARRL President Jim Haynie, W5JBP, has urged ARRL members to contact their US representatives to support the resolution when it reaches the floor of the House. A sample letter is available on the ARRL Web site, although members are encouraged to express their support in their own words. If you're not sure who represents your congressional district, visit the United States House of Representatives Web site.

To expedite delivery, send all correspondence bound for Members of Congress--preferably as an attachment--to hres230@arrl.org or fax it to 703-684-7594. The ARRL will bundle correspondence addressed to each Member of Congress for hand delivery.
