230801-N-GB257-001 Charleston, S.C. (August 01, 2023) The Naval Information Warfare Center (NIWC) Atlantic team spent a few days at the Sullivan’s Island facility testing 5G communication devices over open water. Using a static tropospheric scatter (troposcatter) system located at the main facility and a 27-inch antenna mounted to a moving 35-foot boat, the team tested how far a 5G signal from the shore could be extended out to sea.
