Laboratory of Wireless Technologies 1

Course Description

The purpose of this course is to give the students the practical skills to implement various video communication technologies and practical knowledge about the phenomena related to the transmission of microwave and optical electromagnetic waves. Students gain the insight into video processing methods with applications in communication systems. The restrictions imposed by particular components in the optical communication systems are considered (optical fibers, laser sources, photo-detectors, optical amplifiers). Students will understand the concepts of transmission structures with distributed parameters and microwave phenomena. The course offers an individual hands-on experience about the concepts that are taught in Video Communication Technologies, Optical Communication Systems and Microwave Electronics.

General Competencies
