Abstract
Since about 1980, a new generation has appeared approximately every decade. Mobile phones started with first-generation (1G), then the successful second generation (2G), and then mixed successful auctions since the launch of 3G. According to business terms, 1G and 2G were providing voice and gradually include data (3G is unsuccessful, 4G is very successful). Today, we have 5G with an ultra-high 20 Gb/s bit rate, an ultra-low latency of just 1 millisecond, and a very high capacity. Given the enormous potential of 5G communication networks and their expected evolution,6G communication networks should deliver improved range and data speeds, as well as the ability to connect users from anywhere. This paper details possible 6G communication networks. More specifically, the primary influence of this research is to deliver a complete synopsis of the development of wireless communication networks from 1G to 6G. This paper gives a clear overview of how wireless communication has developed from 1G to the upcoming 6G era. Each generation brought major improvements?starting from basic analog voice calls in 1G to high-speed data, IoT support, and low-latency services in 5G. However, several challenges still remain, such as limited coverage at high frequencies, network congestion, security risks, high energy use, and the need for faster and more reliable connections for new applications like autonomous systems and immersive media. To address these issues, 6G aims to introduce new technologies including terahertz communication, intelligent surfaces that improve signal quality, AI-driven network management, better integration of satellites and ground networks, and stronger security methods. These advancements are expected to deliver extremely high data rates, near-instant response times, improved coverage, and more efficient use of energy and spectrum.
