The kick to stride the new era in wireless communication begins once 5G technologies holding the promises of speeds previously unheard of and extremely low latency with the capacity to connect a large number of devices at once. This article reviews the potential of 5G in transforming such industries as healthcare, driverless cars, smart cities, and the Internet of Things. It discusses enabling technologies such as millimeter waves, massive MIMO (Multiple Input Multiple Output), and network slicing, among others, and also its infrastructure, security, and the possibility of availability of the frequency spectrum. For this purpose, this research aimed to provide an inclusive overview of how this new generation of wireless technology may impinge upon the future of worldwide communication and connectivity by assessing both the benefits and challenges that emanate from 5G.
