This is the next technological trend after the Internet of Things. 3G allows us to browse the Internet, 4G provides high bandwidth so that we can enjoy high definition, and 5G services are expected to revolutionize our society. By enabling AR, VR and MR technologies and cloud-based gaming services (such as Google Stadia, NVidia GeForce Now, etc.), 5G is expected to be widely used in fields such as smart factory control, smart traffic management, smart grid, and smart retail. Say 4G is the communication between people, then 5G becomes three scenarios, that is, people, machines, and things all communicate. At present, almost all telecommunications companies in the world, such as Huawei, Apple, Verizon, Qualcomm, etc., are committed to the development and application of 5G. According to the report, by 2020, the global 5G service market is estimated to reach 41.48 billion U.S. dollars, and it will grow at an annual rate of 43.9% from 2021 to 2027.
