ARLB008 ARRL Supports No Change to Table of Allocations for 45.5 -
47 and 47 - 47.2 GHz Bands

The FCC has opened a brief window for public comment on
recommendations approved by the World Radiocommunication Conference
Advisory Committee (WAC). Comments are due March 18 on International
Bureau Docket 16-185. The FCC said the short comment period was
necessary to allow time to finalize the US position for submission
to the upcoming meeting of the Inter-American Telecommunication
Commission (CITEL).

Addressing WRC-19 Agenda Item 1.13, which serves to identify
spectrum above 24.25 GHz that may be designated for International
Mobile Telecommunications (IMT), ARRL has recommended no change in
the 45.5 - 47 and 47 - 47.2 GHz bands, with hopes that commenters
will agree. The 47 - 47.2 GHz band is allocated to the Amateur and
Amateur Satellite services.

ARRL and other no-change proponents point out that no sharing and
compatibility studies were performed between IMT-2020 systems and
the relevant incumbent services in the 45.5 - 47 GHz and 47 - 47.2
GHz bands, although sharing and compatibility studies for a number
of incumbent services were required under Resolution 238 of World
Radiocommunication Conference 2015 (WRC-15).

"In the absence of ITU Radiocommunication Sector studies, the only
sustainable conclusion is that it has not been demonstrated that the
incumbent services in either band - the Mobile-Satellite Service,
the Radionavigation Service, and the Radionavigation-Satellite
Service in the 45.5 - 47 GHz band, and the Amateur and
Amateur-Satellite services in the 47 - 47.2 GHz band - can be
protected, as required by Resolution 238," asserts the proponents of
View B, which sides with no change to the current allocations.

"In this regard, the View A proposal to identify mobile spectrum in
the 45.5 - 47 GHz band for the terrestrial component of IMT, and to
allocate spectrum in the 47 - 47.2 GHz band to the mobile service
and identify the same for the terrestrial component of IMT, is
fatally flawed. The absence of studies in the responsible ITU-R task
group leaves the proposals unsubstantiated and incapable of
adoption."

View B proponents, including ARRL, are urging the FCC to accept the
proposals of the National Telecommunications Information
Administration (NTIA) for no change to the Table of Allocations in
the 45.5 - 47 GHz and 47 - 47.2 GHz bands.
