The U.S. Department of Defense released its title Wednesday.《5G Ecosystem: Risks and Opportunities for the Ministry of Defense》 The new research also explores the potential of the United States to shape or form the fifth generation of wireless mobile communication technology in the next few years. In particular, it examines how the United States pays attention to mmWave spectrum, coupled with the rise of other companies in building infrastructure hardware and 5G mobile devices, could eventually lead to a fire.
Milo Medin and Gilman Louie, co-authors of the study, warned that "other countries are trying to repeat what happened in the U.S. 4G at 5G." They pointed out that 4G and 4G LTE networks were largely deployed by the United States as early as possible. American companies use this high-speed connection to build applications, devices and services.
Mobile phoneApplications are available all over the world. This initiative has helped to promote the dominance of the United States in global wireless and Internet services, and has created a wireless ecosystem led by the United States, which has been operated by the Department of Defense (DoD) and the rest of the world for nearly a decade.
In contrast, 5G is more complex. The problem is that the 3GHz and 4GHz spectrum for 5G (commonly referred to as sub-6GHz in most other parts of the world) is the unique federal band of the United States. In particular, the Ministry of Defense relies heavily on them.
This has led US operators to focus on mmWave and some limited sub-6GHz (below 6GHz band) utilization. American Airlines and the Federal Communications Commission (which controls the U.S. civil spectrum) are considering mmWave spectrum as a domestic 5G core solution, "because the large band of sub-6GHz spectrum in the U.S. cannot be used for civil/commercial purposes," the study points out.
It is worrying that, without these restrictions, other countries will continue to promote sub-6 GHz technology and create growing differences between international network and equipment manufacturers and the United States. "This could polarize global markets and lead to the adoption of 5G sub-6 technology in most countries of the world," the study warned.
But the Ministry of Defense can't simply hand over all the sub-6 GHz spectrum it relies on. However, the recommendations of the Defense Innovation Commission are still quite intense. "Without the positive actions outlined in this report, we believe that the United States may not be able to convince the rest of the world to adopt mmWave technology as the standard 5G path."
Their recommendations include the conversion of their priorities from mmWave to sub-6GHz by the Defense Department and the Federal Communications Commission. This will mean that the Ministry of Defense and consumers will co-exist or share their bands in a commercial 5G deployment. The study also warned: "The Ministry of Defense should assume that all network infrastructure will eventually be vulnerable to cyber attacks from the point of view of encryption and resilience."
