The FCC has just given notice that, at its December 12th meeting, it intends to consider a Notice of Proposed Rule Making (NPRM) in which it boots hams from the 3.3-3.5 GHz band. The band would be repurposed, and auctioned off, for so-called "5G" mobile service. (Note that there's really no new technology called "5G;" it's just 4G, also known as LTE. But the Commission - several of whose members seem willing to grant any favor requested by the mobile carriers - has gone along with the ruse, supporting the carriers' claims that there is a "race to 5G" which the US absolutely must win lest it become an economic wasteland.) The Notice of Proposed Rule Making can be found at https://docs.fcc.gov/public/attachments/DOC-360941A1.pdf The ARRL has already announced plans to oppose the change: http://www.arrl.org/news/arrl-to-oppose-proposal-to-eliminate-3-3-3-5-ghz-amateur-allocation Alas, the weeklong "sunshine period," during which the FCC does not accept comments on items to be considered at an upcoming meeting, has already started. This means that the Commission won't entertain comments on the item, except by invitation, until after the meeting. However, hams should chime in thereafter regarding this attempt to evict us from a band which is extremely useful for digital communications, including inter-repeater links and mesh networks.
