In contrast to terrestrial investigation only a small number of performed works were focused on scenario for high elevation angle links, and if, only for limited scenario. Over the past decades, a huge number of experimental investigation focused on terrestrial services were performed covering many effects (season, frequency, measurement scenario, type of vegetation, etc.). With new requirements for wireless communication, broadcast quality and data amount, there is a demand to investigate the influence of vegetation shadowing on the propagation channel for terrestrial and satellite communication as well. Selected topics of our workĪll projects Simulation of the radio waves propagation New prospective advanced radio systems represent new requirements on signal propagation research in various frequency bands. A suitable model of signal propagation permits to choose type and location of antennas, optimize quality and reliability of the service, analyze interference etc.

Part of our activities also includes system level simulations. Specific requirements on the appropriate propagation model are based on the actual application. That is why experimental observations and simplifications of general scenarios are unavoidable. weather), local environment on the ground (e.g. Many factors influence the signal propagation, such as random phenomenon which is difficult to describe determinately (e.g. The area of the electromagnetic wave propagation for radio communication systems is comprehensive and diverse. The aim is to find suitable signal propagation models for given environment and given application supported by both theory and experiments. In general, we are focused on research of the electromagnetic waves propagation in the Earth's atmosphere for the needs of radio systems planning.
