A Study on the Impact of 5G in Defense and Security

5G which stands for fifth generation wireless network. Fifth-generation technology is a new standard for broadband cellular networks as it is designed to connect devices and everyone to each other and aimed to provide higher bandwidth with extremely low latency. 5G networks are now being evaluated in several sites throughout the world, with commercial use likely to commence in India in early 2022. This article delves at the potential applications of 5G technology in the sphere of military and conflict situations. After a quick rundown of 5G technologies and how it works, a detailed literature review of research done by authors in the field of 5G with in time span of six years is done along with stating some gaps in their research papers and then a detailed discussion about different key technologies used in 5G network such as - mm Wave, MIMO, Hentet's, D2D Communication, SDN, NFV are talked through. This paper focuses on challenges in deployment of 5G technology. After which it has an incredibly detailed discussion about privacy and security challenges which are linked with 5G because of using foreign equipment and then it provides workable solutions to the privacy and securitychallenges.
