Author Description

The fifth-generation (5G) technology standard for broadband cellular communications is expanding in Europe and will offer many more capabilities than the existing fourth generation long-term evolution standard. With this increase in capabilities comes opportunities for the U.S. Department of Defense (DoD) to integrate advanced technologies and improved communications into its operations. However, these opportunities come with inherent risks. The authors describe the 5G rollout in Europe, characterize what Russian experts have determined regarding the military utility of 5G, and identify DoD opportunities and risks of using the 5G ecosystem in a future Baltics scenario. The research involved literature and document reviews of the 5G rollout and threats to 5G in countries of interest. The authors also conducted a literature review of primary sources, including Russian-language sources, to assess Russian thoughts on 5G. They developed a smart logistics vignette to evaluate the benefits of 5G using a consensus of 11 subject-matter experts (SMEs) on three aspects of 5G across a variety of tasks during the vignette: operational impact of 5G, resilience with 5G, and uniqueness of 5G. Using these reviews, assessments, and SME consensus, the authors identified the risks and benefits of the military's use of 5G in the European theater.
