The four main application scenarios of 5G are continuous coverage, hot spots, high capacity, low power consumption, large connection and low delay and high reliability.

Continuous wide area coverage is the most basic mode of coverage for mobile communication. It aims at ensuring the mobility and continuity of the users, and provides a seamless and high-speed business experience for the users. The main challenge of this scenario is to provide users with more than 100Mbps of user experience rate at any time and anywhere (including the edge of the cell, high-speed mobile and other harsh environments). Hot high-capacity scenes mainly focus on local hot spots, providing users with extremely high data rate and meeting the high traffic density requirement of the network. 1Gbps user experience rate, tens of Gbps peak rates and traffic density requirements of dozens of Tbps/km2 are the main challenges facing the scene.

Low power large connection and low delay and high reliability scene are mainly oriented to the Internet of things service. It is a new development scene of 5G, and the focus of solving traditional mobile communication can not support the application of the Internet of things and the vertical industry. Low power large connection scene is mainly oriented to intelligent city, environment monitoring, intelligent agriculture, forest fire prevention and so on. It has the characteristics of small data packet, low power consumption and massive connection. This kind of terminal has a wide range and a large number. It not only requires the network with more than 100 billion connection support, satisfies the 1 million /km2 connection number density index, but also ensures the ultra low power consumption and ultra low cost of the terminal. Low time delay and high reliability scenes are mainly oriented to the special application requirements of vertical industries such as vehicle networking and industrial control. These applications have high index requirements for time delay and reliability. It is necessary to provide end to end delay of millisecond and close to 100% service reliability guarantee for users.
