Résumé: This letter presents 38-GHz wide-band point-to-multipoint measurement results from various weather events. 73963 measured power delay profiles indicate that multipath can occur due to the foliage and the reflection from wet surfaces during rain. The received signal strength during rain varies according to a Rician distribution with a K factor inversely proportional to the rain rate. The measured rain attenuation exceeds Crane model prediction by several decibels. The results may aid in design of broadband millimeter-wave communication systems.
