The \"5G in defense\" market refers to the adoption and integration of fifth-generation mobile communications technology (5G) within military and defense systems. As opposed to purely commercial uses, this includes private or hybrid 5G networks designed for battlefield communications, tactical edge computing, low-latency command-and-control, ISR (intelligence, surveillance, reconnaissance) systems, and secure data sharing. In this context, 5G enables flexible, high-bandwidth, low-latency connectivity to support advanced military applications such as smart warehousing, augmented reality training, distributed command posts, autonomous systems, and interoperability between coalition forces.
