ARRL opposes FCC plan to delete the 3.4 GHz band

ARRL has filed comments opposing an FCC proposal to delete the 3.3 –
3.5 GHz secondary amateur allocation

The ARRL say:

The comments, filed on February 21, are in response to an FCC Notice
of Proposed Rulemaking () in WT Docket 19-348 in which the FCC put
forward a plan to remove “existing non-federal secondary radiolocation
and amateur allocations” in the 3.3 – 3.55 GHz band and relocate
incumbent non-federal operations. The FCC’s proposal was in response
to the MOBILE NOW [Making Opportunities for Broadband Investment and
Limiting Excessive and Needless Obstacles to Wireless] Act, enacted in
2018 to make new spectrum available for mobile and fixed wireless
broadband use. ARRL noted that amateur radio has a long history of
successful coexistence with primary users of the band.

“There is no reason suggested by the Commission, or known to us, why
the secondary status for amateur radio operations should not be
continued for the indefinite future,” ARRL said in its comments. “We
understand that secondary commercial users are less flexible than
amateur radio users and may desire to relocate to protect continued
provision of services and service quality. Radio amateurs, by
contrast, benefit from having technical knowledge and no customer
demands for continuous service quality, more flexibility to make
adjustments, and often have the technical abilities necessary to
design and implement the means to coexist compatibly with the signals
of primary users.”

ARRL pointed to amateur radio’s “decades-long experience observing and
experimenting with radiowave propagation” in the 3.3 – 3.5 GHz band
that includes mesh networks, amateur television networks, weak signal
long-distance communication, Earth-Moon-Earth (moonbounce)
communication, beacons used for propagation study, and amateur
satellite communications. In its comments, ARRL argued that it would
be “premature” to remove the current secondary amateur radio
allocation.
