The FCC is considering opening the 3.1-3.55 GHz band for advanced commercial services, including 5G. Specifically, the FCC is proposing to remove and relocate the non-federal users in the 3.3-3.55 GHz portion of the band, which currently is allocated for non-federal secondary radiolocation services and amateur use. The item also seeks comment on the relocation options and transition mechanisms for these incumbent non-federal users to the 3.1-3.3 GHz band or to other frequencies.
In addition to these mid-band efforts, we’ve also been hard at work when it comes to high-band spectrum. In January, we finished an auction of spectrum in the 28 GHz band. In May, we concluded an auction of spectrum in the 24 GHz band. And earlier this week, we launched an auction of 3,400 MHz of spectrum in the upper 37, 39, and 47 GHz bands, which is the largest spectrum auction in American history.”
