NEXT GENERATION 5G SATELLITE WIRELESS COMMUNICATION SYSTEMS: CHALLENGES AND EVOLUTION

ABSTRACT: The main objective of this paper is a detailed and comprehensive study about the evolution of the different mobile generation technologies in the wireless communication. This paper also gives an overview of mobile communication technologies developed so far and also throws some light on what can we expect from the future of mobile world. Mobile communication has become a major source for information exchange throughout the world. An year by year, we see lot of development in the world of mobile technology. The 5G-technology stands for the 5th Generation Mobile technology. 5G is a next major phase of mobile telecommunications standards beyond the 4G standards.5G is expected to provide speed upto 10Gbit/s, wider frequency band, high increased peak bit rate, high system spectral efficiency, ubiquitous connectivity and significant increase in QoS as compared to current 4G technology. Evolution of mobile communication technology to 5G is discussed in this review, followed by protocol stack and 5G architecture. A wide comparison is given between the various generations so as to compare why 5G technology is better and needed.
