Resumen
This research is focused on identifying the convenience for Colombia of having adopted the ITU-R P.526-15 deterministic propagation model as an alternative to calculate the coverage of the service area of frequency modulated (FM) sound broadcasting stations. It is intended to establish what is the impact at the technical level generated on the National Technical Plan for Modulated Frequency Sound Broadcasting (NTPMFSB) in force to date and make a contrast with respect to the probabilistic propagation model supported on the E curves (50,50) of the (NTPMFSB), used until the November 2020 version adopted through Resolution 360 of 2020. For this purpose, simulations, calculations of coverage of the service area of FM Sound Broadcasting stations and their due graphic representations were considered, in representative areas of the Colombian relief, which, added to the incorporation of technical characteristics assigned by MinTIC, and field strength measurements, allowed validating the accuracy of the propagation models UIT-R P.526-15 and E curves (50,50). Considering the above, it was determined that the use of the ITU-R-P 526-15 propagation model is convenient, taking into account that the measurements made in the field were more consistent with those simulated with the HTZ Communications tool, which allows carry out timely planning and management of the radio spectrum and better surveillance and control of it.
