Development in human society can be easily observed after every innovation. Due to never ending needs, human beings always try for something new faster and smarter technologies. In the field of communication there is a huge development from first generation to fifth generation mobile communication We are now in the era of 5G technology. Here 5G Technology stands for Fifth Generation of Mobile technology. The network of Fifth generation offers inexpensive and faster broadband wireless connectivity. This paper presents a comparison between the different network architecture of fourth and fifth generation technology. The standards of 4G provide extensive with accessible voice, data and streamed multimedia at “Anytime and Anywhere”. Support for Global mobility is also provided by the Global mobility protocols like IPv6. In the fifth generation, focus has been given on voice over IP (VOIP) enables devices, in which a high level of call volume and faster data transmission can be observed by the users. In a 5G network users have been offered simultaneous connection to multiple users and switching between them. This latest technology supports IPv6 and flat IP. The purpose of this paper is to provide a detailed study of 4G and 5G technologies, in terms of their characteristics, their contributions and behavior in terms of QoS. The difference and similarities have also been studied to present the requirement to merge the LTE and WiMAX.
