Wireless systems have a significant advantage: Unlike wired systems, they do not require costly infrastructure installation and allow for mobility. The lecture provides fundamental knowledge for the setup of wireless systems, which includes electromagnetic wave propagation, antenna selection, and feeder line dimensioning, as well as wireless network planning. This is explored through examples of Wi-Fi, mobile telephony, broadcasting, and satellite communication.

1.      Electromagnetic Fields and Waves

2.      Antennas

3.      Measurement and Analysis of High-Frequency Signals (Theory of Electrical Lines, Smith Chart, Scattering Parameters)

4.      Radio Channel

5.      Radio Network Planning

6.      Multiplexing and Duplexing Techniques; Spread Spectrum Methods

7.      Wireless Systems (Local Wireless Systems, Broadcasting, Mobile Telephony, Satellite Communication)
