Summary
The student gets information about the technologies and principles of information transmission in metallic, optical, wireless and access networks. He/She will understand their use and understands the techniques of different types of communication networks. The generation of an electrical signal and its adaptation for transmission in various kinds of environments puts the student in the broad field of communication technologies. Of course, at the application level, attention is paid to problematic of the multimedia tranfering and the future of communications that belong to the next generation networks. Students will also acquire basic information from imageand sound processing and also the fundementals of the security in communications is not neglected. This knowledge forms the pillars for future telecommunication education. Conclusion of the course belongs to the vision and concrete examples of the use of communication technologies in practice.
