Land Mobile Service communication systems are widely used by different sectors of the industry in the country, however, the allocation of frequencies over the territory requires a precise management to avoid interference and make the best use of the scarce resource of the electromagnetic spectrum. This article numerically determines the distance separation that should exist between Land Mobile Service devices, operating in the band between 30 MHz and 470 MHz, to ensure that there is no interference. The Monte Carlo method was used to simulate the system, based on the interference probability, the effect of co-channel interference, adjacent channel and blocking was considered for different propagation models and different scenario sizes. The results indicate that according to the propagation model, the minimum separation distances can vary from 108 km between stations operating at the same frequency and increase as different aspects are considered in the system modeling.
