English
The fifth generation mobile communication technology is the abbreviation of 5G.
translate freely
5G is a new generation of broadband mobile communication technology, which has the characteristics of high speed, low delay and large connection, and is the network infrastructure to realize man-machine Internet of Things.
Application scenario
The International Telecommunication Union (ITU) has defined three major application scenarios of 5G, namely, Enhanced Mobile Broadband (eMBB), Ultra-high Reliability and Low Delay Communication (uRLLC) and Mass Machine Communication (mMTC).
1, Enhanced Mobile Broadband (eMBB) mainly aims at the explosive growth of mobile Internet traffic, and provides a more extreme application experience for mobile Internet users;
2. Ultra-high-reliability and low-delay communication (uRLLC) is mainly used in vertical industries that require high delay and reliability, such as industrial control, telemedicine and autonomous driving.
3. Mass Machine Communication (mMTC) is mainly aimed at smart cities, smart homes, environmental monitoring and other applications aimed at sensing and data acquisition.
Development background
Mobile communication continues the development law of one generation technology every ten years, and has experienced the development of 1G, 2G, 3G and 4G.
From 1G to 2G, the transformation from analog communication to digital communication has been realized, and mobile communication has entered thousands of households. From 2G to 3G and 4G, voice services have been transformed into data services, and the transmission rate has increased by a hundredfold, which has promoted the popularization and prosperity of mobile Internet applications.
As a new type of mobile communication network, 5G not only solves the communication between people, but also provides users with more immersive extreme business experiences such as augmented reality, virtual reality and ultra-high definition (3D) video. It should also solve the communication problems between people and things, and meet the needs of Internet of Things applications such as mobile medical care, car networking, smart home, industrial control and environmental monitoring.
In the end, 5G will penetrate into all industries and fields of the economy and society, and become a key new infrastructure supporting the digital, networked and intelligent transformation of the economy and society.
