Over the years, wireless technologies have advanced from theoretical establishments to readily applied engineering techniques that play a major role in many aspects of modern life. The first-generation (1G) wireless network has fulfilled the basic mobile voice, while the second-generation (2G) wireless network has introduced capacity and coverage. This is followed by the third-generation (3G) wireless network, which has quest for data at higher speeds to open the door for truly “mobile broadband” experience, which was further realized by the fourth-generation (4G) wireless network. The 4G wireless network provides access to a wide range of telecommunication services, including advanced mobile services, supported by mobile and fixed networks, which are increasingly packet based, along with a support for low- to high-mobility applications and a wide range of data rates, in accordance with service demands in multiuser environment. Fifth-generation (5G) should be a more intelligent technology that interconnects the entire world.
