This Recommendation contains a general purpose wide-range model for terrestrial propagation which predicts path loss due to both signal enhancements and fading over effectively the range from 0% to 100% of an average year. This makes the model particularly suitable for Monte-Carlo methods@ and studies in which it is desirable to use the same propagation model@ with no discontinuities in its output@ for signals which may be either wanted or potentially interfering. The model covers the frequency range from 30 MHz to 50 GHz@ and distances from 3 km to at least 1 000 km.
