From the Executive Summary: "Emerging 5G [fifth generation] network technology offers the Department of Defense (DoD) access to advanced communications and networking with much improved data rates, lower latency, and significant potential energy savings over existing 4G [fourth generation] networks. The integration of 5G technology could give DoD an opportunity to adopt at lower cost the benefits of these systems for operational needs. Improved commercially available 5G technology offers DoD many operational benefits but also presents new challenges in cyber security, spectrum management and network optimization. The Defense Science Board (DSB) Quick Task Force (TF) on Defense Applications of 5G Network Technology was established to define a path for potential DoD 5G adoption that mitigates supply chain risk, establishes spectrum co-existence procedures and revamps existing communication infrastructure."
