Increase in transmission rate

At present, the 5G network has successfully downloaded 1.8Gbps in the 2.6GHz band, and the peak of 28G millimeter wave experimental scenarios reached 8Gbps, while the current long -term evolution (4G LTE) service transmission rate is only 100Mbps.

Flexible support for various different equipment

In addition to supporting mobile phones and computers, 5G networks also support wearing devices such as smart watches, travel devices such as cars, and various smart home appliances to achieve real -everything.

Can accommodate more network links

5G can support a million -level connection per square kilometer, and 4G is about 2,000.

Improve the battery life of the equipment

The energy consumption of the 5G network transmission unit has decreased by one -third of the energy consumption of 4G. The Internet of Things equipment supports more energy -saving characteristics. It can achieve a significant improvement in the life of the battery life of IoT equipment. The battery can continue to use it for several years.

Industrial field

The application of 5G in the industrial field covers four major industrial links of R & D design, manufacturing, operation management, and product services. It mainly includes 16 application scenarios, which are: AR/VR R & D experimental collaboration, AR/VR remote collaborative design, remote remote range Control, AR auxiliary assembly, machine vision, AGV logistics, autonomous driving, ultra -high -definition video, equipment perception, material information collection, environmental information collection, AR product requirements introduction, remote after -sales, product status monitoring, equipment predictive maintenance, AR/VR Remote training and so on.

Internet and autonomous driving

The 5G network's bandwidth, low latency and other characteristics support real -time business such as car VR video calls and real -life navigation. With the help of the low latency, high reliability and broadcast transmission characteristics of the C-V2X (including direct communication and 5G network communication), the vehicle can be broadcast its own basic security news such as the positioning and operating status in real time. It can be used to broadcast traffic management and instruction information to support applications such as intersection collision warning, traffic light induction traffic, etc., which significantly improves the safety and travel efficiency of vehicles. In the future , Vehicle formation, etc.

Energy field

At present, the application of 5G in the field of power is mainly based on the four links of transmission, substation, power distribution, and power consumption;

In the field of coal mines, 5G applications involve underground production and security guarantee. The application scenarios mainly include: video surveillance, environmental information collection, equipment data transmission, mobile inspection, and remote control of operating equipment.

education field

The application of 5G in the field of education mainly focuses on both smart classrooms and smart campuses.

medical field

By empowering the existing smart medical service system, 5G improves the service capabilities and management efficiency of remote medical, emergency rescue, and has given birth to new application scenarios such as 5G+remote ultrasound inspection and intensive care monitoring.

Field of cultural tourism

Through 5G technology, the application of various innovative technologies such as AR guide in the field of cultural tourism will help culture and tourism industry into a fast track of digital transformation.

Smart city field

5G helps smart cities to improve management and service levels in security, inspection, and rescue.

Information consumption field

While 5G brings changes and innovation to the vertical industry, it also bred emerging information products and services to change people's lifestyle.

The financial sector

Fintech -related institutions are actively promoting the application exploration of 5G in the financial field, and the application scenarios are diversified.
