Shared Spectrum Role to Grow

Shared spectrum is likely to be used in several ways in the U..S. market first to support 4G, and then likely in more-intensive forms as 5G is introduced.

Among the U.S. bands where spectrum sharing will be key is about 500 MHz of capacity in the Wi-Fi 5-GHz band, as well as about 150 MHz in the 3.5-GHz Citizens Broadband Radio Service (CBRS) band. In Europe, the 2.3-GHz band will be where shared spectrum first is tried.

Spectrum sharing also is expected around  the 60-GHz band, where  7 GHz is available for sharing in the frequency ranges between 57 GHz and 64 GHz, and where an additional 7 GHz of capacity is being considered for shared use.

Spectrum sharing also is being evaluated in the licensed 71 GHz to 76 GHz band and 81 GHz to 86 GHz bands which have in the past been used for point-to-point radio links.
