The following is the June 12, 2019 Congressional Research Service In Focus report, National Security Implications of Fifth Generation (5G) Mobile Technologies.
From the report
The fifth generation (5G) of mobile technologies will increase the speed of data transfer and improve bandwidth over existing fourth generation (4G) technologies, in turn enabling new military and commercial applications. 5G technologies are expected to support interconnected or autonomous devices, such as smart homes, self-driving vehicles, precision agriculture systems, industrial machinery, and advanced robotics. According to a Defense Innovation Board (DIB) report, in the military realm, 5G will additionally improve intelligence, surveillance, and reconnaissance systems and processing; enable new methods of command and control; and streamline logistics systems for increased efficiency. As 5G technologies are developed and deployed, Congress may consider policies for spectrum management and national security, as well as implications for U.S. military operations.
