AI for 5G

Interview with Prof. Dr.-Ing. Thomas Wiegand

Prof. Dr.-Ing. Thomas Wiegand is one of the two directors of the Fraunhofer Heinrich Hertz Institute in Berlin and has been involved in mobile communications for many years. He was a driving force behind the foundation of the innovation cluster 5G BERLIN e.V., a partnership between research and industry to promote innovation relating to 5G. The editorial staff of InNOVAtion spoke with Prof. Wiegand about the newly founded association and about 5G technology.

InNOVAtion: What particular technological challenges do you see in the introduction of the 5G standard?

Wiegand: The technological challenges lie explicitly in the implementation of the ambitious key performance indicators (KPIs), such as 1 ms latency and a data transfer rate increased by a factor of 100-1000 compared to 4G. The better compression of future networks also poses a particular financial challenge. 

InNOVAtion: MicroNova is especially active in the field of automatic rollouts and network configuration of multi-vendor and multi-technology radio access networks – what insights can you give our readers and customers with regard to 5G? 

Wiegand: Operating future networks will become increasingly complex – networks must therefore configure themselves automatically. This will increasingly be realized automatically via software and artificial intelligence (AI). One challenge is the hardware-related design and alignment of base stations. Multi-vendor activities will only become interesting once regional and “private” 5G network licenses are awarded and will enable smaller providers to participate in the market for the first time.
