Summary/Abstract: A methodology for calculating the parameters of radio paths operating with ionospheric reflection that depends on the state of the ionosphere and at a given distance of radio communication is presented. Based on the critical frequencies of the ionospheric regions E (foE) and F (foF2) and the maximum usable frequency at a distance of 3000 km (MUF3000), the electron density profile is reconstructed and the geometry of the radio wave reflection from the ionosphere is determined. As a result of the modeling, the frequency range of the radio waves at which radio communication is possible is determined; the latter is limited by the lowest usable frequency (LUF) and the highest usable frequency (MUF) illustrated by an example.
