Rain-induced attenuation creates one of the most damaging effects of the atmosphere on the quality of radio communication systems, especially those operating above 10 GHz. Accordingly, methods have been devised to overcome this destructive impact. Adaptive fade mitigation schemes have been proposed to mitigate the rain fade impact in terrestrial communications above 10 GHz (e.g., Sweeney & Bostian, 1999). These schemes mainly deal with the temporal variation of rain attenuation. When such methods as site diversity and multi-hop relaying are to be used, or when the impact of adjacent interfering links is concerned, the spatial variation of rain must also be considered (Hendrantoro et al, 2002; Maruyama et al, 2008; Sakarellos et al, 2009; Panagopoulos et al, 2006). There is also a possibility of employing a joint space-time mitigation technique (Hendrantoro & Indrabayu, 2005). In designing a fade mitigation scheme that is expected to work well within a specified set of criteria, an evaluation technique must be available that is appropriate to test the system performance against rainy channels. Consequently, a model that can emulate the behavior of rain in space and time is desired. This chapter presents results that have thus far been acquired from an integrated research campaign jointly carried out by researchers at Institut Teknologi Sepuluh Nopember, Indonesia and Kumamoto University, Japan. The research is aimed at devising transmission strategies suitable for broadband wireless access in microwave and millimeter-wave bands, especially in tropical regions. With regards to modeling rain rate and attenuation, the project has gone through several phases, which include endeavors to measure the spacetime variations of rain intensity and attenuation (Hendrantoro et al, 2006; Mauludiyanto et al, 2007; Hendrantoro et al, 2007b), to appropriately model them (e.g., Yadnya et al, 2008a; 14
