In these past few decades, we have witnessed the rise in technology at a very progressive rate with introduction of the first generation (1G), the second generation (2G), the third generation (3G), the fourth generation(4G) and now the fifth generation(5G) mobile technology is being deployed. Each generation is concentrated in terms of bandwidth and real-time applications. The channel and bandwidth have reached their capacity to hold and gorge the end users and also the number of connected devices which leads to channel bandwidth to reach its maximum capacity. In order to fulfill the demands of increasing users and connected devices a new technology is introduced which is know is 5G technology. The key advantages of 5G technology as: utilized the millimeter wave (mm Wave) bandwidth, high throughput, and low latency. This paper is intended to provide a broad perspective on mobile generations and the evolutions from 4G to 5G technology. ©2019 by Begell House, Inc.
