Development of mobile communication is rapid, with different methods and techniques being introduced in wireless communications. The next few pages will deal with the detailed study of wireless cellular technologiesâfirst, second, third, and fourth generations eventually leading to the fifth generation as well. This will visualize the evolution from analog system transmissions to digital transmissions which brought the usage of audio, graphics, video, etc. The evolution also gave rise to Internet on the cellular mobile phones which were once realizable only in computers through broadband connections. With improved technologies, we saw the development of fourth-generation cell phones which harnessed the use of LTE. The world is moving very fast, and the corporates involved in mobile communications are in a strong tussle to achieve the fifth generation of mobile networks which will shift the worldâs entire way of functioning from autonomous vehicles to IoT and many other things which could be seen only as part of sci-fi movies.
