The FCC is considering secondary mobile use of most of this band, adding to the groundswell of interest created by the plans to use 4.5 GHz for 5G in China and Japan.

But wider adoption is likely to be hampered by NATO’s use of the band in Europe, as Toby Youell explains.

5G in 26 GHz: a technical note on the implications of interference to passive satellite services

The ability to use 26 GHz for 5G is limited by the need to protect satellite earth observation services in 24 GHz. But what are the engineering issues behind this? Independent consultant Roberto Ercole explains how they affect the commercial prospects for the band and could influence operators as they choose whether to deploy 26 GHz or 28 GHz.
