Comparison of Algorithms and Technologies 2G, 3G, 4G and 5G

Technology has always been on the agenda of important world events and continues to be the main topic with perspective in the future as well. The practical relevance of the topic is about understanding the speeds that different networks have on different mobile phones whether Android or iPhone with proportions each different from each other. This paper discusses each generation characteristics and provides more accurate visions for technology development and the advancement of new technologies ranging from 2G to the latest as the most advanced 5G. Analysis and the difference of 2G, 3G, 4G and 5G Technologies and algorithms is made. In the end, an experiment using Android and IOS Smartphones is made as related to their download speed of three different files including a video, a picture and a music file.
