What has 4g changed? What has 5g changed? How to fill it out?

4G changes life and 5G changes society.

The ideas of various scenarios of 5G are highly targeted, and support for autonomous driving and car networking is proposed for the automobile industry; For the medical industry, the ideas of telemedicine and portable medical care are given. For the game industry, give AR/VR support; For the government, it puts forward the support of a more ambitious smart city.

For agriculture, there is smart agriculture; For the traditional furniture and home appliance industries, a higher Internet of Things support is proposed. For industry, it is proposed that the revolution of Industry 4.0 can be supported by ultra-low delay and ultra-reliable network.

5G lightning technology will accelerate the interconnection process, which may be 20 times faster than the 4G currently used. The same movie may take 26 hours to download with 3G, 6 minutes for 4G and 3.5 seconds for 5G.

Extended data

The 5G network is developing towards network diversification, broadband, integration and intelligence. With the popularity of various intelligent terminals, mobile data traffic will show explosive growth in 2020 and beyond.

In the future 5G network, reducing the cell radius and increasing the number of low-power nodes is one of the core technologies to ensure that the future 5G network can support 1000 times traffic growth. Therefore, ultra-dense heterogeneous networks will become the key technology to improve data traffic in future 5G networks.

In the future, wireless networks will deploy 65,438+00 times more wireless nodes than existing sites. Within the coverage of the macro station, the distance between the stations will be kept within 10 meter, serving 25,000 users within 1 square kilometer.
