ARLA/CLUSTER: ARRL pede à FCC para proteger as faixas de ondas milimétricas para radioamadores

 ARRL asks FCC to protect ham radio millimeter-wave bands

ARRL has asked the FCC to avoid authorizing developmental technologies in
two Amateur Radio bands above 95 GHz that some radio amateurs may not be
unaware of.

The ARRL commented on May 2 in response to a Notice of Proposed Rule Making
and Order (NPRM&O) in ET Docket 18-21, released in February.

The so-called “Spectrum Horizons� proceeding seeks to make the bands above
95 GHz “more readily accessible for new innovative services and
technologies.� ARRL said that, while it agrees that “regulatory flexibility
is justified� in the millimeter-wave bands above 95 GHz, due to the
extensive frequency re-use possibilities, the FCC ought to make two primary
Amateur/Amateur Radio Satellite bands in that part of the spectrum
unavailable for deployment of unlicensed Part 15 or Part 5 Experimental
Spectrum Horizons devices. Amateur Radio has primary allocation status in
the bands 134 – 136 GHz and 248 – 250 GHz, both shared with the Radio
Astronomy Service, which is secondary.

“The amateur allocations require protection against increases in the noise
floor due to aggregate radio frequency devices,� ARRL said. “The bands are
used ubiquitously and unpredictably, typically, but not always, at high
elevations for research and development purposes and propagation studies,
for terrestrial point-to-point, satellite, and Earth-Moon-Earth
communications experimentation.�

ARRL said it would oppose “any proposal to permit unlicensed devices or
largely unregulated experimental operations� in the two primary Amateur
Radio allocations in the range of spectrum the FCC is considering. “It is
critical to preserve for Amateur Radio experimentation the current
relatively quiet noise floor, and the positive RF environment that now
exists in those two relatively small band segments,� ARRL told the FCC. The
League’s comments noted that the secondary Radio Astronomy Service in those
two bands also requires a quiet RF environment.
