What is the difference between 5g and 4g

The difference between 5g and 4g: 1. Speed ​​and capacity; 2. Delay; 3. Connection density; 4. Energy consumption; 5. Peak transmission rate; 6. Air interface delay; 7. Device connection capability ; 8. Spectrum efficiency; 9. Non-stationary connection experience rate; 10. Traffic density; 11. Use in mobile state; 12. Security. Detailed introduction: 1. Speed ​​and capacity. The transmission speed of 5G network is faster than 4G. In theory, it can reach dozens of times or even higher speed. 5G network also provides higher network capacity and can support more device connections; 2. Delay, etc.

The difference between 5G and 4G is mainly reflected in the following aspects:

1. Speed ​​and capacity: 5G The transmission speed of the network is faster than 4G, and can theoretically reach dozens of times or even higher speeds. At the same time, 5G networks also provide higher network capacity and can support more device connections.

2. Delay: The delay time of the 5G network is shorter than that of 4G, and the communication response is more immediate, providing better support for real-time applications (such as autonomous driving, telemedicine, etc.).

3. Connection density: 5G network can achieve higher connection density, support large-scale Internet of Things device connections, and provide better solutions for application scenarios such as smart cities and industrial Internet. Scalability.

4. Energy consumption: Compared with 4G, 5G network consumes less energy when transmitting the same amount of data, which can extend the battery life of terminal equipment.

5. Peak transmission rate: The peak transmission rate of 5G is between 10~20Gbit/s, while the peak rate of 4G is 100Mbps downlink and 50Mbps uplink.

6. Air interface delay: The air interface delay of 5G is less than or equal to 1ms, while the delay of 4G network is relatively long.

7. Device connection capability: 5G has the device connection capability of one million connections/square kilometer, while the connection capability of the 4G network is relatively weak.

8. Spectral efficiency: The spectrum efficiency of 5G is more than three times higher than that of LTE technology (including Volte), while the spectrum efficiency of 4G is relatively low.

9. Non-stationary connection experience rate: 5G’s non-stationary connection experience rate must reach 100Mbit/s, while the connection experience rate of 4G network is relatively low.

10. Traffic density: The traffic density of 5G reaches 10Mbps/m2, while the traffic density of 4G is relatively low.

11. Use in mobile state: 5G supports use in high-speed mobile state of 500KM/h, while the performance of 4G network in high-speed mobile state is relatively poor.

12. Security: 5G is more secure than 4G and can use more advanced encryption technology to more effectively protect user privacy and data security.

To sum up, the differences between 5G and 4G are mainly reflected in speed, capacity, delay, energy consumption, device connection capabilities, spectrum efficiency, security, etc. 5G has higher performance and wider application scenarios, which will bring more possibilities for future smart life and industrial applications.
