Millimeter wave wireless networks with diversity against localized rain

In this paper, an evaluation of the influence of rain and its attenuation on link performance in a Tokyo Institute of Technology (Tokyo Tech) millimeter-wave model mesh network are presented. The unique effects arising due to the highly localized behaviors of strong rainfalls have become clear and are characterized in terms of variogram rather than correlation coefficients. Spatial separation even in the small network here with links of less than 1 km provides effective diversity branches for better availability performance.
