Real-Time Geographical Spectrum Sharing by 5G Networks and Earth Exploration Satellite Services

Out of band emissions from 5G transmissions in proposed mm-wave spectrum between 24 and 86 GHz (New Radio 2 or NR2 bands) has the potential to corrupt sensitive measurements of atmospheric water vapor and ice made in adjacent bands allocated to Earth Exploration Satellite Services (EESS). These measurements provide critical data for weather forecasting, and for understanding extreme weather events. A new mechanism - Real-Time Geographical Spectrum Sharing (RGSS) - that protects EESS measurements while adjacent NR2 spectrum is used for 5G communications, is proposed.
