ARLA/CLUSTER: ARRL comenta proposta da FCC sobre expansão dos 5 GHz para estações não licenciadas

ARRL comments on proposed expansion of 5 GHz unlicensed broadband

Observing that "a decision in the near term with respect to the
addition of [unlicensed National Information Infrastructure] U-NII
devices to the 5.85-5.925 GHz band would be premature," the ARRL has
commented in response to an FCC Notice of Proposed Rule Making (ET
Docket No. 13-49) that proposes to authorize U-NII use of an
additional 195 MHz of spectrum in the 5.35-5.47 GHz and 5.85-5.925 GHz
bands.

The Commission was obligated, pursuant to Section 6406(a) of the
Middle Class Tax Relief and Job Creation Act of 2012 (Public Law No.
112-96), to begin a proceeding to allow U-NII devices in the 5.35-5.47
GHz band. As the ARRL comments note, "There is no legislative
obligation, however, to make available the 5.85-5.925 GHz band for
U-NII use."

The Amateur Radio Service has a longstanding secondary allocation of
5.65-5.925 GHz, with an amateur-satellite uplink band at 5.65-5.67 GHz
and a downlink at 5.83-5.85 GHz. In its 14-page filing, the ARRL
traces the history of "a continuing series of overlays" to which the
band has been subjected over the past 16 years, progressively reducing
the utility of the amateur allocation. In 1999, the Commission
allocated 5.85-5.925 GHz for direct vehicle-to-vehicle and
vehicle-to-roadside, or "Dedicated Short Range Communications" (DSRC).
Amateurs may continue to operate in this segment, but only to the
extent that they do not interfere with DSRC operations. In support of
its argument that the introduction of
U-NII into this segment would be premature, the ARRL observes that
"...a U-NII overlay at the present time requires a good deal of
compatibility analysis, none of which has been completed to date."
