Abstract
This paper describes a new methodology to be utilized in assessing the level of coordination difficulty on the basis of the actual terrain profile between IMT-Advanced (fixed and mobile users) and FSS (Fixed satellite services) for a specific site. This methodology can be use to asses the effectiveness of mitigation techniques based on the use of directional antennas, which takes into account the actual shielding effect by terrain profile and clutter losses associated with the artificial objects. Considering a shielding effect on the signal propagate within proper separation distance used to improve the current methodology. Mathematical approach was simulated by Mat lab and results confirmed by ICS Telecomm software for more specifications. Eventually, the results had been summarized in planned methodology to serve regulators and frequency management modulators.
