5G is not a gimmick!

It will eventually realize the overall vision of “information is at your fingertips, everything is within reach”. At present, major countries around the world are seizing 5G commercial deployments, competing for the high ground of a new round of industrial chains, and the fierce competition between countries is not just for a “gimmick”. At the same time, we must dialectically see that the popularization and application of 5G is a gradual process, not an overnight one. Regarding whether the 5G era has arrived, we can’t make it clear in only a few words but should seek to establish a more systematic and objective perception.

What is the difference between 5G network and 4G network?

1) The speed has been greatly improved. The theoretical rate of the 5G network has reached 10G. Downloading a 1G movie can be done in a few seconds. When 5G is officially commercialized, the download rate of wireless access can reach about 1G, which is a qualitative improvement compared to the current 4G network.

2) Base stations are denser 4G uses base stations, which is what we usually call “iron towers”, and can achieve coverage in the range of several kilometers. The 5G network uses millimeter wave technology because the frequency is higher, so the coverage is small and the anti-interference ability is weak. Covering the same area, the number of 5G base stations will be dozens of times that of 4G base stations, and the dense networking of small base stations will become the mainstream in 5G (this will also bring high costs).

3) Larger-scale “antenna array” In a 4G network, each base station has a maximum of 8 antennas. 5G base stations use “antenna arrays”, with hundreds of antennas distributed in each array. 5G mobile phones will also adopt the antenna array method accordingly. The advantage of this is that it can provide better and better coverage, and provide users with new experiences such as 4K ultra-high definition.

What is the difference between 5G chips and ordinary chips? Answer: According to the equipment used, 5G chips are divided into base station equipment chips and mobile phone chips. Compared with ordinary chips, the most obvious difference of 5G chips is that it not only supports low-frequency bands below 6GHz but also extends to millimeter-wave bands from 26.5 to 300GHz, which is the biggest bright spot. It should be noted that the requirements of 5G chips for equipment and processes are very high

The advantages of the current 5G mobile phone: Under normal 5G network environment, the rate can generally reach more than 200Mbps, or even reach 1Gbps, and can experience the high speed of the 5G network first.

The disadvantages of current 5G mobile phones: mobile phone and network compatibility issues, heat dissipation and battery life issues (all currently being resolved), and the price is relatively expensive

In addition to mobile phones, what content does the layout of the 5G industry chain include?

1. Virtual reality, Internet of Vehicles, Internet of Things, unmanned driving and other emerging technologies;

2. Intelligent application of industry, medical treatment, transportation, etc .;

3. Cloud games;

In recent years, more and more smart technologies have been applied to automobiles. However, the requirements of intelligent technology for data communication support are quite high, especially in the field of autonomous vehicles. For example, the car is driving on the road, and it is necessary to avoid the road in parallel; if the network speed is not strong, the autopilot system reacts for 1second slower, the final result may be that the car is killed and killed … With the service capability of 1ms delay, the ubiquitous 5G network provided by the operator can provide a strong security guarantee for autonomous driving. Therefore, 5G is a prerequisite for autonomous driving. Products and solutions related to the 5G industry, such as industrial Internet, unmanned driving and Internet of Vehicles, are promising. With the development of 5G, it will definitely promote the development of the industrial Internet and accelerate industry intelligence. This is a general trend. After the intelligent interconnection of all things is realized, it is expected to truly subvert various industry scenarios.
