Supporters of the changes say the revision would facilitate the deployment of 5G services.

After a pitched battle over net neutrality this year, the Federal Communications Commission is preparing for a fierce fight this fall over sharing the spectrum used for wireless communications.

Similar to a pending vote on net neutrality, the Oct. 24 FCC meeting is likely to see the 3-2 Republican majority set in motion the rollback of a key Obama-era policy.

The battle centers on a rule adopted by the FCC in April 2015, which provides access to the 3.5 GHz band of the spectrum, known as the Citizens Broadband Radio Service. Commissioners are scheduled to vote this month to explore rule changes for licensing terms for spectrum in the CBRS band.

Licenses are currently offered for shorter times and for smaller geographic areas than in other spectrum bands, lowering the barrier to entry for smaller players that would be able to afford to bid for guaranteed access to the spectrum in an auction.

The changes that are being proposed would lengthen the license period from three years to the typical 10 and expand the licenses’ geographic area from individual census tracts to larger economic areas called Partial Economic Areas that can include multiple counties.
