Course Description

Basic characteristics of wireless systems are described, with an emphasis on mobile systems. The phenomena in the wireless channel and methods of suppressing the influence of the channel on the reliability of communication are studied. A cellular planning overview and the basics of MIMO technology are given. The most important mobile systems are presented, with a more detailed look on features of 5G network.

Learning Outcomes

  1. Explain the basic features of a wireless channel and equalization techniques.
  2. Explain the main characteristics of mobile systems from different generations.
  3. Evaluate correctness of cellular planning.
  4. Explain the basics of MIMO technology.
  5. Recognize the main features of 4G network.

Forms of Teaching

Lectures

Lectures are conducted with the help of power-point presentations with explanations on the board. Lectures are available online in electronic form.

Exercises

Solving numerical examples.

Independent assignments

During the semester, projects from the course area are planned. More complex tasks would be solved, most often with the use of software tools. Each project would be handled by smaller group of students.

Laboratory

Laboratory exercises are planned during the course. At the end of each exercise, the activity and understanding would be check.
