Description 408-413
The nature and characteristics of tropical rainfall have called for the need to investigate horizontally polarized radio signals from Earth-to-Satellite link and to estimate intersystem interference due to hydrometeor in the tropical climate. Two rain cells, Awaka and Capsoni models, are used and results obtained from these models are compared. A difference of 5 dB has been observed between effective transmission loss (Le) and transmission loss (L) for Awaka model, whereas it is about 8 dB for Capsoni model at 0.01% of time unavailability (outage time). This suggests higher interference level in Awaka model for terrestrial and satellite communication operating at frequency above 10 GHz. The statistics of effective transmission loss over frequencies variation, station separation and terrestrial antenna gains have also been considered.
