New data turbo creates 70 gigabits per second

By 2020, mobile data traffic will grow eightfold worldwide. More than one exabyte – the equivalent of one billion gigabytes – will then buzz through the air in digital form per day.

Even the powerful LTE can not do this. This already requires 5G-the next generation of mobile technology. And this is one of the key topics at the Mobile World Congress (MWC), which takes place in Barcelona from 22 to 25 February. Almost all mobile companies show what 5G can do there, from the providers to chip manufacturers such as Intel and Qualcomm to network equipment manufacturers such as Huawei, Ericsson and Nokia.

5G is intended to provide 100 times more users per mobile cell with particularly fast Internet than currently used networks can. In order to cover larger areas and enable stable data traffic, the mobile operators will accommodate large numbers of small transmitters in house facades and billboards that can send data to the smartphones nearby.

In turn, several antennas are installed in the mobile devices in order to be able to receive this data – from numerous base stations at the same time. This stabilizes the connection by 1000 times. And also the classic voice connection will be more reliable. Messages such as” The recipient is temporarily unavailable ” are now a thing of the past.

In a second, the movie is on the phone

This also applies during a rapid journey in a car or train, as 5G can reliably send data to smartphones and tablets when they are moving at high speed. And the technology thinks along: Should it ever get tight in the frequency range, the app gets data particularly quickly, which currently requires many. Another, less data-intensive application will then have to wait.

But most importantly, 5G is fast. 100 Megabits per second is the minimum, the telecommunications company Verizon assumes a gigabit. Under optimal conditions, it is ten or even 70 gigabits per second, as Telekom and Huawei have now shown in a record attempt.

And this pace has its advantages. This allows even complex apps to be downloaded to the smartphone in fractions of seconds. A movie is thus available on the mobile device within a second. With LTE, such a download often takes a minute. Even high-resolution HD videos would be loaded after just a few seconds and not just after ten minutes.

Thanks to the high speed of downloading, users will also be able to download 3-D movies on the go to their smartphone or tablet. This is also possible: watching a sports broadcast on the go – live and from many hundreds of different camera perspectives.

Nokia wants to show such an application at the MWC and let smartphone users look at a stadium or a racetrack from an angle of their choice-without the images jerking. Nokia also shows how users throw themselves a ball and catch it without being able to see themselves in real life. Instead, they wear virtual reality glasses, and the images recorded there are transmitted via 5G. With only a slight delay in the data transfer, most would always fall into the void.

5G makes self-driving cars possible

In any case, thanks to the new technology, games could become a particularly stimulating experience, not on the PC or TV screen, but with a view of the smartphone display. Because 5G is not only particularly good at transferring data quickly, the technology also reacts particularly quickly.

The latency period – the time, for example, from the selection of a website to its appearance on the display-should be significantly reduced. While UMTS needs more than 30 and LTE between ten and 20 milliseconds, 5G responds in less than a millisecond. So you can also daddle online action games without annoying delays.

The short latency time of 5G is also interesting for the use of self-driving cars, as network equipment manufacturers show at the MWC. The technology in the autonomous cars has to react very quickly, after all, it depends on fractions of seconds to avoid accidents.

For this reason, equipment suppliers also place the base stations in which the data is processed directly on the motorways. If the digital information were first sent to a server in the USA and back again, it would take too long. Cloud computing is not a viable solution for such kind of application.

The ability of 5G to set priorities also comes into play here: brakes and warning lamps in the car will definitely provide the mobile radio of the future with data, while other applications such as a radio-fed music system will be supplied in a subordinate way. Around 2020, this would create one of the – at least technical-prerequisites for putting self-driving cars on the road. Until then, the network should be available and the standard for it should be developed.

The surgeon operates patients remotely

Only then will there be the first devices with which users can use the technology. Most of the functional test devices are still as big as a refrigerator, the first models almost fit into a shoe box.

5G also serves another technology trend: the Internet of Things. There is already talk of billions, trillions, even trillions of devices that will be networked in several years – the TV at home with the smartphone, the street lamps with passing cars or the sensors in the field with the weather service server. And the data between them can then be exchanged via 5G radio.

At the MWC, robots will be on display that do exactly the same thing, at exactly the same time – controlled by the new mobile radio technology. In the future, a far bolder scenario is conceivable, with which Ericsson plans, among others.

A surgeon in Hamburg puts on virtual reality glasses, puts on robotic gloves and begins to operate virtually. The 5G network transmits his every movement almost in real time to remote-controlled instruments, which cut the thyroid gland of a patient in Oberstdorf. A stable network with tiny response time, as technicians with 5G promise, is vital for this.
