I. Different abilities:
The capacity of 5G is expected to be 1000 times that of 4G. With 4G network, you really can't play games online on your mobile phone in real time, but with 5G network, you can.
The 4G network is specially built for mobile phones and not optimized for the Internet of Things. 5G technology provides huge bandwidth for the Internet of Things. Compared with 4G, 5G network can support devices with 10 times or more.
Second, the network speed is different:
A video of 10G takes 15 minutes to download for 4G and 9 seconds for 5G. The intelligent control reaction distance of driverless brake is 1.4m for 4G and 2.8cm for 5G. In the future, the number of 5G base stations will exceed 4G, and fully enjoying the existing resources can realize 5G low-cost rapid network deployment.
Performance index
1, and the peak rate needs to reach 10-20Gbit/s, so as to meet the needs of high-definition video, virtual reality and other big data transmission.
2. The air interface delay is as low as 1ms, which meets real-time applications such as automatic driving and telemedicine.
3. It has the equipment connection capability of one million connections/square kilometer, and meets the communication of the Internet of Things.
4. The spectrum efficiency is more than 3 times higher than that of LTE.
5. With continuous wide-area coverage and high mobility, the user experience rate reaches100 mbit/s. ..
