5G Evolution Differences between Basic 4G LTE with 5G Network

Abstract

Wireless communication is one of the fastest growing area today. Wireless devices are growing exponentially day by day. The need for massive data transmission is growing and growing every year. Some of the prime goals or demands that need to be addressed in the near future, i.e. beyond 4G, are increased efficiency, higher data speeds, decreased latency and better service quality. To meet these demands, there needs to be dramatic changes in the design of the cellular network. Some of the main 2020+ timeline services include smart city applications that require smart grid, smart infrastructure, smart medicine with connected vehicles, connected houses, moving robots and sensors that build the Internet of Things environment. 5G is the fundamental IoT connectivity infrastructure that can handle extremely high power, high bandwidth, robust integrity and low latency. This represents a number of innovative and disruptive advancements in technology. This paper comprises of basic comparison between 4G and 5G characteristics. It covers how 5Gs architectures differs from 4G architecture and what are the advantages and characteristics of 5G. First, 4G and 5G network architecture are pointed out. Second, overview of technological advancement of 5G over 4G is discussed.
