An Overview of 5G Technology Evolution with Cases on Drone, Smart Healthcare and Smart City

Abstract

Since its inception in the late 1970s, the evolution of mobile wireless communication technology has exerted a profound influence on diverse industries, enterprises, and the quotidian lives of average consumers. The progression from 1G to 4G has witnessed remarkable technological leaps. With the maturation of 4G and the advent of 5G, our global landscape stands on the precipice of an era characterized by ceaseless and ubiquitous communication that interlinks virtually every conceivable device, thereby revolutionizing myriad facets of commerce and individual livelihoods. This article provides an exhaustive overview of the evolutionary trajectory of 5G technology, elucidating the developments in the domain, and elucidates three quintessential 5G applications: unmanned aerial vehicles (UAVs), intelligent healthcare systems, and smart urban environments. Each application is meticulously examined, thereby spotlighting potential security apprehensions that are intertwined with them. Additionally, we proffer strategic approaches for the amelioration of vulnerabilities in each scenario, offering invaluable insights for prospective research endeavors. In particular, future research endeavors ought to grapple with the escalating surge in cybercrimes, exemplified by burgeoning attack surfaces consequent to the burgeoning multitude of Internet-connected devices within the ambit of 5G wireless technology.
