3g era is the beginning of mobile Internet. Please talk about 3g, 4g, 5g and the developing 6g mobile communication network.

From 3G, 4G, 5G to the developing 6G mobile communication network, each upgrade brings faster network speed, lower delay and wider coverage.

1, 3G era: This is the beginning of the mobile Internet, which provides faster network speed and better stability, enabling users to use the Internet on mobile devices, such as browsing web pages and sending emails.

2.4G era: 4G network further improves the network speed and stability on the basis of 3G, reduces the delay, and enables users to download and upload data faster and watch videos more smoothly.

3.5G era: 5G network is the latest generation of mobile communication technology, with extremely high network speed, ultra-low delay and wide coverage. It can support more devices to be connected at the same time, provide faster data transmission speed, and is suitable for large-scale Internet of Things, intelligent transportation, industrial automation and other fields.

4.6G era: The 6G network currently under development will further upgrade the network speed and coverage, and pay more attention to network security and privacy protection. 6G may also support higher data transmission speed and lower delay, and support more devices to be connected at the same time.

Characteristics and advantages of mobile communication technology from 3G to 6G.

The first generation of mobile communication technology uses analog signals for voice communication, which is slow and has a small coverage. The second generation of mobile communication technology, using digital signals for voice communication, can send short messages and transmit data, which is faster than 1G and has a wider coverage. The third generation mobile communication technology can carry out high-speed data transmission and video call, which is faster than 2G, but the coverage and signal quality may be reduced.

The fourth generation mobile communication technology provides higher data rate and better signal quality, and supports high-quality streaming media and online games. The fifth generation mobile communication technology provides higher data speed, lower delay, larger network capacity and better coverage, and supports more devices and applications.

6G is still in the research stage and is expected to be commercialized around 2030. 6G will adopt brand-new technology and frequency band, which has the characteristics of faster speed, lower delay, larger capacity, stronger security and reliability, and can be applied to more fields, such as virtual reality, augmented reality and artificial intelligence.
