1、1Successful Military Radar and 5G Coexistence in the Lower 3 GHz Band:Evidence from Around the World2The lower 3 GHz band is used for 5G in nearly 50 countries,demonstrating real-world successful coexistence with U.S.military radars deployed abroad.The global communications industry has aligned on t

2、he lower portion of the 3 GHz band3300-3450 MHzas a core 5G workhorse,providing the capacity needed to connect the industries of the future.Nearly 50 countries are already using full-power 5G networks in the lower 3 GHz band,with even more planning to do so soon.1 Over 70 countries in total are plan

3、ning for or using 5G in this band.More than 30 of those countries feature 5G deployments that are successfully coexisting with the same U.S.military radar systems that are used domestically,strongly suggesting that 150 megahertz of full power,licensed spectrum can be made available from 3.3-3.45 GHz

4、 in the U.S.without risking harmful interference to those military systems.2 New research from GSMA,CCS Insight,and DLA Piper detail these operations abroad,investigating 5G networks using lower 3 GHz spectrum near various radar operations.Together,these reports provide key insights on the widesprea

5、d global use of 5G alongside U.S.military bases and radar systems deployed abroad.The global spectrum environment for lower 3 GHz spectrum is rapidly commercializing,a reality that the U.S.military must accommodate in its spectrum and international threat response planning.This real-world evidence d

6、emonstrates how proven coordination methods are already facilitating simultaneous use of the band by 5G and military radars.Segmenting the band at 3.3 GHz with commercial wireless operating above and military radars tuning below can facilitate near-term coexistence.Coordination techniquessuch as ret
