Introduction to 5G in the world

5G is the latest development of wireless communications. It is expected to be introduced worldwide in 2020. Compared with previous fourth-generation mobile communication systems, 5G can achieve higher bandwidth and lower latency, allowing people to experience more immersive entertainment via the Internet and remote medical treatment through a variety of devices. 5G networks will be the first to achieve 1 Gbps wireless speeds thanks to an improved wireless link layer and a new air interface (5G NR), along with many other enhancements. 5G is a disruptive technology that poses more risks than benefits. While its applications for telecommunications and the Internet are only in their infancy, 5G’s safety threats are already well understood. The security of our families and homes are at risk from the millions of unsecured devices that will be used worldwide. 5G is the next generation mobile technology that will give users incredibly fast, low-latency connections. This new technology will allow more people to connect more devices, all at once, making it the most revolutionary wireless tech to date. 5G stands for fifth generation, and it’s the latest iteration of connectivity that follows 3G and 4G. 5G is a massive and complex project that is on its way to build a new generation of wireless mobile networks. It will allow us to carry out not just voice calls, but also very fast internet connection, video and virtual reality, remote surgery and many other things. 5G standardization and research are at their initial stages and the technologies necessary for development have not yet been agreed on. The development of 5G technology is currently under way. In the future, 5G networks are expected to support more connections at higher speeds, with a higher degree of reliability and flexibility. 5G will support a broader range of applications than previously possible and offer an improved performance for existing applications. 5G is not just a technology; it’s a revolutionary concept that will spawn new industries and applications. These new services will be available to almost every industry and impact virtually every aspect of our lives, including entertainment, healthcare and education, infrastructure such as smart cities, energy and transport as well as financial services. 5G mobile networks are being tested and deployed globally by many operators. This book offers an overview of the status and implementation of 5G mobile networks that are currently being developed in the world. For each country, a detailed discussion is provided on existing testbeds and implementations, along with related standards and plans for future developments. In addition, the book provides an overview of related technologies such as IoT (Internet of Things), M2M (Machine to Machine), smart cities, connected cars and autonomous vehicles. 5G technology will revolutionize the way we live and work with additional services and applications in cellular networks, such as high-speed broadband connections to Internet of Things (IoT) devices, thus becoming an essential part of our every day lives. 5G has the potential to make all things digital better, faster and stronger. As 5G becomes available over the next few years, it will transform the way we look at our smartphones, homes and cities when it comes to connectivity. All of this improvement is a direct result of the increased speed, responsiveness and reliability that 5G will deliver.
