Pending Government Legislation
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) was introduced on
April 21st, 2005. The resolution, H. Res 230,
says the Commission should comprehensivelyevaluate BPL's interference potential
incorporating "extensive public review and
comment," and - in light of that analysis - to "reconsider and
review" its new BPL rules. (ET Docket 04-37)
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 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. It also cites comments filed by
the Missouri State Highway Patrol, which uses a statewide radio system with more
than 1400 Low-Band VHF users. The Missouri State Highway Patrol commented that
the overall effect of
BPL implementation would be "a potentially significant increase in
interference to the mission of critical public safety communications," the
resolution says.
The resolution recounts 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.
