The Financial Benefits of Shared Spectrum Licensing

A study commissioned by Spectrum for the Future has highlighted the financial benefits of shared spectrum licensing over exclusive spectrum models. The study points to the CBRS band as an example of how the spectrum sharing model can work economically and drive more cumulative value.

While early shared-licensed auctions like the CBRS auction may have raised less money than exclusive license auctions, it does not necessarily imply that the underlying value of the spectrum has decreased. The study also emphasizes the importance of selecting the right sharing framework and valuing a shared licensed regime accurately.

“Shared spectrum licensing offers significant financial advantages compared to exclusive spectrum models. The success of the CBRS band demonstrates the potential economic benefits of shared spectrum. It’s important to understand that the value of spectrum cannot be solely measured by the revenue generated from auctions. The value lies in the opportunities created for multiple users to access and utilize the spectrum efficiently.”
