5G at RWTH Aachen University

In Spring 2020 the IT Center was commissioned by the university management to coordinate the development and establishment of 5G technology at RWTH Aachen University. The main goal of the RWTH Aachen University is to create a location where this technology and its fields of application can be researched and used by the RWTH and its partners. Upon application, the Federal Network Agency has granted the RWTH Aachen University a license to use the industrial spectrum in the field of Campus Melaten.

Together with the partners of the 5G-Industry Campus Europe (Fraunhofer-Institute for Production Technology IPT, Research Institute for Industrial Management at RWTH Aachen University e.V. (FIR), Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University, IT Center of the RWTH Aachen University) a production network 5G for the use by different use cases is to be established. This development is to be financed by suitable projects and pushed forward in terms of content. For the necessary scientific exchange, workshops are regularly organized to which invitations are issued university-wide. These workshops also serve to determine (long-term) needs.

What is 5G?

As successor to 4G (LTE), the 5G network is revolutionizing mobile communications. The 5G technology is up to 100 times faster than LTE and thus makes real-time transmissions possible. Furthermore, an extremely high data rate is available, so that services with high broadband requirements are supported.

Specified 5G performance characteristics:

  • Bandwidth for transmission capacities above 10 GBit/s
  • Latency of less than 1 ms
  • 10 to 100 times the number of connected devices
  • 10 times lower energy consumption
  • Area-wide 5G access even for less densely populated areas

The lower the frequency, the better the radio waves spread and penetrate possible resistances like walls. However, less data is transmitted. Networks with high frequency are more powerful, but cover less area and penetrate obstacles less effectively.
This is why the frequencies for 5G are higher than for LTE. This is the only way to achieve faster data rates.
