Abstract: Mobile communication systems have made remarkable changes in the field of communications in a short period of time making history in wireless technology. The evolution of these wireless technologies has reached the fourth generation, 4G. It has made major improvements in terms of performance and efficiency in communication environments. The early first generation 1G only had the basic voice system, and then in the second generation 2G the coverage area and storage capacity was taken into consideration. Later the third generation 3G took over both first and second generation by fulfilling faster speeds using mobile broadband. Lastly fourth generation was introduced that provided a wide variety of communication services with help of both fixed and mobile networks. They also have a wide range of data rates providing service demands at a multiuser environment. In this paper we have talked about the overview of evolution in mobile communication systems.
