FCC Chairwoman Jessica Rosenworcel says the agency will take a different approach than usual for regulating the 42 GHz band.
Traditionally, the FCC has relied on auctions to allocate spectrum licenses. However, Rosenworcel expressed her belief that the agency had overinvested in millimetre wave (mmWave) auctions while neglecting mid-band spectrum.
In recent years, the FCC has made efforts to address this by launching auctions in the 3.45 GHz and 2.5 GHz bands.
Now, with successful mid-band auctions behind them, the FCC is shifting its attention back to mmWave spectrum. However, Chairwoman Rosenworcel is seeking a different approach this time.
“With the help of my colleagues, we quickly launched auctions in the 3.45 GHz band and 2.5 GHz band. With those successful mid-band efforts in the rear-view mirror, we are now turning back to millimetre wave—but this time we want to consider something different,” says Rosenworcel.
The FCC has initiated a proceeding to explore the possibility of shared uses in the 42 GHz band, marking a shift in its approach to spectrum management. The commission’s move aims to encourage competition and maximise opportunities in mmWave spectrum, particularly for smaller wireless service providers.
The 42 GHz band offers a unique opportunity as it has 500 megahertz of untapped airwaves without federal or commercial incumbencies. Non-exclusive access models could help to make the most of this greenfield spectrum.
“This could entail using a technology-based sensing mechanism to help operators detect and avoid one another. It could involve non-exclusive nationwide licenses that leverage a database to facilitate co-existence. It could also entail site-based licensing,” explains Rosenworcel.
The goal of this initiative is to lower barriers to entry, foster competition, and unlock the potential of mmWave spectrum. Chairwoman Rosenworcel expressed her eagerness to develop new models and share them with the world, emphasising the need for creativity in spectrum management.
The FCC’s action sets in motion a Notice of Proposed Rulemaking (NPRM), which will gather input and feedback on the benefits and challenges of implementing a shared licensing approach in the 42 GHz band.
The NPRM proposes dividing the band into five 100 megahertz channels and seeks comments on coordination mechanisms, buildout requirements, and technical rules for shared licensing.
By exploring new models and harnessing mmWave spectrum, the FCC aims to create an environment that maximises the potential of wireless connectivity, benefiting both service providers and end-users alike.
“Our goal here is to come up with a new model to lower barriers, encourage competition, and maximise the opportunities in millimetre wave spectrum. In short, it’s time to be creative. I look forward to the record that develops—and then look forward to sharing our creativity with the world,” concludes Rosenworcel.
