Via the ARRL: US Department of Defense to Share 3450 – 3550 MHz with 5G Commercial Operations

The FCC will auction sharing rights to the upper 50 MHz of the 3300 – 3500 MHz secondary amateur radio allocation to commercial 5G interests in the wake of the Department of Defense (DoD) agreement to share spectrum at 3450 – 3550 MHz. The entire band currently supports a variety of military operations, and amateur radio has a long history of peaceful coexistence with the Department of Defense as a secondary user of this spectrum.

Late last year, the FCC proposed to delete the amateur secondary 3300 – 3500 MHz secondary allocation as well as the amateur-satellite allocation at 3400 – 3410 MHz. The FCC could auction the 100 MHz of spectrum in early 2022. This latest move makes a contiguous band of spectrum from 3450 – 3980 MHz available for commercial 5G networks.
