What changes does 5G bring into space

5G: The whole truth about the next generation of cellular communications

The mobile operators in Germany are preparing for the next frequency auction. In the end, they should pay a few billion euros for it again. But the new 5G mobile communications standard is set to revolutionize the world because everything will be networked with one another in the future. In fact, fast mobile internet could soon be as natural as electricity is today. But many expectations of 5G are exaggerated, and some ideas are simply wrong. WELT answered the most important questions.

What does 5G stand for?

The mobile communications industry is an orderly industry, it numbers its technology generations through. 1G referred to the analogue voice transmission. We have been digital since 2G. With 3G, the mobile internet speed became significantly faster thanks to UMTS technology. 4G is the current standard that is operated with Long Term Evolution (LTE) and already enables high data speeds. Because the development between the generations did not stand still, there were always intermediate stages. Germany is now facing the fifth generation of mobile communications, i.e. 5G. The standardization is complete.

What can the technology do?

It can transfer data at speeds of up to 20 gigabits per second, which is 100 times faster than a reasonable 4G connection. However, that is not the most important. Above all, the reaction speeds in the network are very short with in the best case one millisecond, which is also called latency.

The answer to a request takes place practically without delay. Not least because of this, 5G is always mentioned as a prerequisite for autonomous driving, where fast reaction speeds are important. However, a car must also be able to drive autonomously if it ever finds itself in a dead zone. That is why 5G will not be a mandatory requirement for this.
