A Wide Range Propagation Model

This paper introduces a new Wide Range Propagation Model (WRPM) suitable for terrestrial network planning and for network simulation. The new model is applicable to all terrestrial radio services operating in the frequency range 30MHz to 50GHz and is unique in covering all time percentages from 0–100%. It has been developed for the UK regulator, Ofcom under a two year research project and is intend to be submitted to the ITU-R to form the basis of a new recommendation. To gain acceptance within the international community, where possible the procedures used in determining the characteristics of each propagation mechanism have been based on methods used within the latest ITU-R Recommendations.
