5G/Weather Satellite 24 GHz Spectrum Disagreement: Anatomy of a Spectrum Policy Issue

Discusses spectrum policy issues that impact 5G mobile communications. The issue that stimulated all this activity is the creation of one of several new cellular bands for fifth generation (5G). The band under consideration near 24 GHz is close to a band that is used by passive satellite sensors to detect water vapor, and there are concerns that out-of-band-emissions from 5G base stations and/or mobile units might in aggregation degrade the performance of the passive satellite sensor and thus hinder weather forecasting.
