ABSTRACT
Over the past few decades, the need for wireless connectivity has increased dramatically. The 6G network represents the future generation of wireless networks beyond the current 4G and 5G technologies. It promises enhanced capabilities through the utilization of flexible and greater frequency bands and cloud-based networking technologies, enabling significantly faster speeds and ultra-low latency in the range of microseconds. While the fifth-generation (5G) technology is currently being deployed, the development and availability of 6G networks are already in progress. Although some companies are investing in the advancement of 6G, industry standards and requirements for 5G-compatible network products are yet to be established. This chapter provides an overview of 5G technologies and their future developments. In comparison with 4G, 5G promises to offer faster data speeds, more capacity, low latency, widespread device connectivity, constant quality of experience, and lower costs and to raise the bar for mobile communication. The greater bandwidth is the most significant advantage of 5G over 4G, and it will allow numerous new opportunities for businesses that want increased efficiency or more and faster data. Even as 5G implementation is still somewhat limited (for instance to only some developed countries), wireless communication firms are already planning for the upcoming mobile network. This chapter gives a detailed overview of the 5G cellular system, 5G in the IoT, and 5G and beyond.
