Focus of the lecture is the procurement of fundamental knowledge for the description and calculation of the propagation of electromagnetic waves in mobile radio communications systems. Essential subject areas are the description of the propagation effects free space propagation, reflexion, scattering and diffraction, the characterisation of the system-theoretical properties of the radio propagation channel, wave propagation models, procedures for network planning, and fundamentals of multiple antenna systems (MIMO).
