Radio Frequency Engineering and Propagation Models

Radio frequency (RF) engineering is central to the design and deployment of wireless communication systems. This track addresses the principles of RF circuit design, transmission lines, amplifiers, filters, and mixers used in modern transceivers. Participants will gain insight into frequency planning, impedance matching, and RF front-end optimization to ensure efficient signal transmission and reception. Understanding RF behavior is critical for minimizing losses, interference, and distortion in wireless systems.

Equally important are propagation models that characterize how radio waves travel through different environments. This track explores large-scale and small-scale propagation effects, including path loss, shadowing, multipath fading, and Doppler spread. Empirical and analytical models for urban, suburban, indoor, and rural scenarios are discussed. By combining RF engineering principles with accurate propagation modeling, this track enables participants to design wireless systems that perform reliably under real-world conditions.
