Abstract
The inter-annual variability of rainfall rate and rain attenuation statistics is an important subject, since it defines the confidence interval that an operator must consider in order to guarantee a certain QoS. This variability can now be assessed through the ITU recommendation P.678-2. The present work performs a qualitative assessment on the suitability of this recommendation, based on a database of 8 years, comprising rain attenuation at Ka-band and rainfall rate, collected concurrently, in Aveiro, Portugal, with the former HotBird-6 satellite.
