As per information from FCC,  the Commission is closer to opening up underused portions of the 2.5GHz band for 5G.

Referring to the remarks from FCC, Mid-band 2.5GHz spectrum is viewed as particularly advantageous for future 5G networks as it can support high capacities and travel far distances compared to the inherent shortcomings of millimeter wave spectrum, which has been used for some initial 5G-powered deployments. While millimeter wave spectrum supports super speeds, it's only usable over very short distances.

The plan to free up 2.5GHz spectrum fits into the FCC's "5G FAST" plan for freeing up capacity for 5G networks and services. FCC noted that Mid-band spectrum, which offers an important combination of 5G coverage and capacity, is central to its strategy. Moreover, much of the band has been unused for decades.

The FCC proposed to consider an updated framework for licensing spectrum in the 2.5GHz band (2496MHz – 2690MHz) last May. The action centers on licensing of the Educational Broadband Service (EBS) spectrum.

 The FCC action involving 2.5GHz follows a recent announcement for the FCC to hold spectrum auctions in the 37GHz, 39GHz and 47GHz bands on Dec. 10, 2019 that will involve the release of 3,400 MHz of spectrum.
