The telecommunications world and the world of data network technology are increasingly growing together. Meanwhile, traditional telephone services such as voice calls are carried partly or completely over data networks. The training of professionals from the telecommunications sector towards IT is necessary to be prepared for the upcoming developments in the telecommunications market.

This course provides an introduction to the network technology and is geared to the knowledge and understanding of people from the telecommunication area. Constant reference to telecom and practical content with specific exercises in our  lab (Router, Switches, PCs) increase the efficiency of our training. The fundamentals are practiced by Wireshark trace of a training network by the participants themselves.

The trainer has many years of experience in both, telecommunications and network engineering. Course language and course materials are in English.
