Impact of Attenuation due to Atmospheric Gases on the Communication Signal for fixed Satellite Links in Abuja, North Central Nigeria

Reliable microwave link system requires models that are location-dependent with meteorological data from location of consideration. Adaptation and analytical a different climatological pattern often prove inadequate when used for another location. Hence, prediction attenuation attributed to water vapor oxygen in Abuja (9.0765⁰ N, 7.3986⁰ E), Nigeria development mathematical model using Meteorological (pressure, temperature vapor) the study area at range five (5) years. Thereafter, newly developed (gaussian, exponential linear models) were applied derive new parameters wide frequency K band, Ka X Ku S band C respectively both (North Central). The proposed therefore, show significant improvement over ITU-R sense that, Root Mean Square Error (RMSE) obtained X-band, Ka-band, S-band C-band bands is lower than those model.
