3.4 GHz Discussion

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 on line, 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 segment.


The AREDN Project Core Team will participate in band plan discussions with groups representing other Amateur interests. Look to this thread for updates and discussion.
