5G at the ZKI Spring Conference 2021: IT Connects – Innovation & Operation

March 12th, 2021 | by

On the occasion of the ZKI Spring Conference 2021 (German only), which was hosted by the IT Center of RWTH Aachen University, Sven Jung from the Fraunhofer Institute for Production Technology (IPT) spoke on the topic:

5G-Industry Campus Europe – Opportunities and challenges of the new mobile communications standard for research.

Exciting presentation of Sven Jung on the topic 5G!

Sven Jung is in charge of the technical setup of the 5G network at the IPT, where he is referred to as ICE (Industry Campus Europe). He predicts that 5G will be for industry in the future what 4G (LTE) was for the smartphone back then. From 1980 to today (2020), a new mobile communications generation has been developed each time. It started with 1G and today has already reached 5G.

Jung sees the potential of 5G in real-time communication, reliability, high device density, high data rates and good scalability, among other things. Expressed in numbers: download 20 GB/s, uplink 10 GB/s, latencies less than 1ms, and 100x connected devices.

The increased industry demand for 5G is due to its high security, greater flexibility, higher accuracy, and new business models.

But there is also reluctance: Studies showed that around 50% of users are skeptical about the introduction of 5G networks. Whereby financial experts expect a significant increase in the gross domestic product (GDP) by 2030 through the use of the new technology in the industrial sector.

This was followed by the presentation of a project of the Fraunhofer Institute. The 5G Industry Campus Europe. On an area of 1 km², an outdoor network with the industrial spectrum 3.7-3.8 GHz was created with the participation of the IT Center, among others. It serves various research projects with different use cases.

A few questions from the audience at the end rounded off Mr. Jung’s exciting presentation.

Jung saw the still existing asymmetry between download and upload speeds in the historical growth of mobile networks. The focus in the consumer sector has always been on downloads. This is also the case with the new 5G technology.

Many listeners were interested in the difference between the two technologies, 5G and WLAN, and what advantages one or the other wireless network offers*.

Mr. Jung was of the opinion that many use cases can also be implemented with WLAN – and made the use of the technology dependent on the number of use cases. For many use cases, the use of 5G is worthwhile. Another advantage is that a regulated spectrum is used in this network and the associated security against interference.

We would like to thank Mr. Jung for this presentation, which helped to bring the new 5G technology closer and to enrich the ZKI Spring Conference.
