Experimental Study on Terrestrial Links Enhancement at 11 and 38 GHz

A detailed analysis of 1-year, long-term experimental measurements of signal enhancement at a terrestrial link between two cities in the Czech Republic is presented with respect to an interference and frequency coordination analysis based on recommendation ITU-R P.452-14. Three different models for terrain diffraction are considered to demonstrate a significant influence on signal enhancement predictions. The impact of radiometeorological parameters, serving as inputs for recommendation ITU-R P.452-14, was addressed by utilizing available ITU-R and ERA-Interim maps, or, their locally obtained values. Monthly and seasonal variations are discussed in addition to the 1-year signal enhancement statistics.
