Abstract
The area of mobile communication is fast developing as a result of the technological advancement in the field of mobile and wireless communication. Obviously, 3G was once acclaimed as a recent technology in the field of wireless and mobile communication until the arrival of 4GLTE. The quest for a faster speed, lower latency, better QoS and ability to interoperate with all existing network are some of the factors that brought up the emergence of 4GLTE network. In this paper we provide an overview of all network generations from the first generation to the fourth generation as well as the differentiating features that supports the superiority of the 4GLTE network to the 3G network are well stated. We use self-analytical tools like bar charts to compare the features of 4GLTE and 3G networks. The concluding part of this paper presents improvements needed in 4GLTE.
