Comparative Studies among 3G, 4G & 5G in wireless communication

Abstract

This paper gives the information about the comparative study of 3G, 4G & 5G wireless communication technologies. The third generation 3G was very much popular in era of 2000 to 2015. It provides the better download speed about 2-100Mbps, low cost robust etc. But it has some disadvantages. To overcome the drawbacks of 3G, the fourth generation 4G comes in picture, which is very popular now a days. But the 4G technology is struggling to meet their performances goal. The fifth generation development initiative is based on 4G to overcome its shortcoming. The comparison between 3G & 4G technology in relation to its speed, bandwidth, architecture and switching design basis is studied , and discovered that their performance are still unable to eliminate problems like poor coverage, poor speed, poor quality of service & flexibility. To overcome all those problems, 5G technology model is proposed.
