Do driverless, smart home, telemedicine, etc. must have 5G to achieve?

1. The reason for the over-promotion of 5G before. It is estimated that people in the communications industry know who started it. It is not until the revenue of some companies has been reduced and marketing expenses have been cut due to well-known reasons that the popularity of 5G has declined. Lou Jiwei, the former Finance Minister, stepped up to speak, and now he has more views on 5G rational thinking.

Of course, 5G technology has made progress. It can provide faster wireless data services; but the disadvantages of 5G technology are also very obvious. The investment is too large and operators are unable to build as fast as the 4G era. The 5G built in more than two years The number of base stations may be comparable to the 4G base stations built in the first year of the 4G era.






The operation and maintenance costs of 5G base stations are extremely high. The most obvious one is that the electricity costs of 5G base stations are too high. It is estimated that the electricity costs for operators to build 5G networks covering the whole country will be more than 200 billion, so that the current number of 5G base stations is only caused. The huge electricity bills have forced operators to shut down 5G base stations during idle periods.

2.Do driverless, smart home, telemedicine, etc. must have 5G to achieve?

This is actually a wrong concept. Some of the technologies of unmanned driving are now in use. For example, Tesla has already put the autonomous driving technology into use. Consumers in the United States often announce that car owners are sleeping on the highway and the autonomous driving technology will send them to their destinations. The United States currently Mainly still use 4G network.

It is not mobile communication technology that hinders the use of unmanned driving technology. It is because autonomous driving technology is far from reaching a mature stage. The industry believes that current autonomous driving technology can only reach the L2 level.

If the technology of smart home and telemedicine is mature enough, the practical wired broadband can be realized, because the machines and equipment used in this kind of technology need to be driven by electricity, naturally they must be connected to the wire, so connecting these devices with wired broadband will be relevant It’s not a problem that our technology becomes a reality.
Compared with 5G, wired broadband has higher reliability and lower latency. For remote surgery, wired broadband is much more reliable than 5G. You can imagine that even 5G has a millisecond-level latency, even a few milliseconds. The difference in scalpel may kill people.

The impact of time delay on autonomous driving technology is actually similar. They advertise that the importance of 5G to autonomous driving technology is low latency, and use the computing power of the cloud to ensure driving safety with ultra-low latency. However, this is actually very dangerous. Yes, the continuation of the intermediate time may also lead to fatal accidents.

In this way, for autonomous driving technology, relying on the computing power of the machine on the car to deal with emergencies in driving more quickly can ensure driving safety. If the computing power of the machine on the car is relied on, it will be superior to mobile communication. The low latency requirement will be reduced.

Therefore, a rational discussion on 5G by all parties can help everyone to have a deeper understanding of 5G technology, instead of having to involve 5G in everything, it is more appropriate to slow down the development of 5G, and let all parties in the communications industry further improve 5G technology. , Reducing costs and improving reliability may be more conducive to the development of 5G.
