5G Development and Modern Applications

5G is the fifth generation of mobile communication technology. It is a perfection and innovation based on 4G technology, which greatly improves the transmission speed of data information. With the gradual integration of 5G wireless communication technology into people's daily life, It has higher transmission efficiency, data information coverage, etc. in practical applications, and has a good development prospect in the future communication industry. This paper takes the key technologies of 5G as the research object. On the basis of expounding the basic characteristics and development status of 5G technology, it analyzes the key technologies and their applications of 5G, and analyzes their development status in smart medical care, transportation and agriculture. 5G technology will provide people with more efficient and affordable remote treatment in the future. With the blessing of 5G technology in transportation, people's travel will be more convenient , and rail transportation will also usher in new opportunities. It can give full play to the carrying capacity of rail transportation and share the burden of express transportation for road transportation. In terms of agriculture industry, the characteristics of 5G technology make agricultural development more intelligent and rely less and less on labor, which not only improves the efficiency of agricultural sowing and harvesting, but also reduces the probability of low crop yields. This article will provide a reference for people to explore the application and development of 5G and more advanced communication technologies in all walks of life in the future, or guide the development direction of communication technology.
