Path loss due to rain fading and precipitation in 26 GHz LMDS systems: consideration of implementation in Turkey

This paper explains the rainfall attenuation prediction model recommended in ITU-R PN.838 and investigates the variability of 26 GHz LMDS radio channel obscured by rain attenuation in seven representative cities for the climate of Turkey. Model is applied both with recommended input values presented in ITU-R PN.837-1 and values obtained by processing long term monthly precipitation data for Adana, Ankara, Antalya, Erzurum, Istanbul, Izmir, and Samsun. Results for both applications are presented and the necessity of using location-specific monthly climate statistics for the LMDS system design is addressed.
