Note: The following has significant impact our use of the 3.4 GHz spectrum as part of our MESH network here in the Anchorage area…….
Great news! Amateur secondary use is being allowed to continue throughout
the 3.3-3.45 GHz band indefinitely, pending future FCC action. This
decision is great news considering the FCC’s original proposal in December,
2019, was to clear amateurs out of the entire band immediately. Consistent
with our secondary status, amateurs must ensure that signals are enough below
3.45 GHz so as to not cause harmful interference to the new commercial
operators when they come online, as well to protect federal government
operations throughout the band.
As far as the 3.45-3.50 GHz segment, Amateur secondary operations must
cease 90 days after Public Notice that the auction for that spectrum has
closed. ARRL’s FCC Counsel estimates the final cessation date to be in
early 2022, so we likely have just under a year of transition time on that
The AREDN Project Core Team will participate in band plan discussions with
groups representing other Amateur interests. Look to this thread for updates
