Mobile communications is a growth market of central importance for many industries worldwide. Within mobile communications, the focus is on the establishment and expansion of 5G networks, because 5G offers very high bit rates on the one hand, and very short runtimes and such high reliability on the other, as is required in the automation of industrial processes.
The key component of mobile communications is the Radio Access Network (RAN). O-RAN concepts are planned to ensure very high bit rates and at the same time a large area coverage. Thus, numerous manufacturers and providers have organized together in the O-RAN Alliance to develop open and thus cost-effective methods for building and operating the infrastructures. This course covers important concepts of modern O-RAN.

Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.
