Millimetre wave utilisation and propagation research in the Czech Republic

TESTCOM is engaged in an experimental propagation research in the frequency bands over 10 GHz. The research is especially focused on attenuation due to hydrometeors on line-of-sight paths. The aim of our research is to obtain long-term radio and radio meteorological data in our climatic conditions and to use them for proposals of cumulative distributions of attenuation due to hydrometeors for the average year and the average worst month. These distributions are applied to the calculations of quality and reliability of terrestrial fixed systems.
