	%X In this paper, the link quality in SHF and EHF ranges
are studied. In order to achieve high data rate higher frequencies must
be used – centimeter waves (SHF), millimeter waves (EHF) or optical
range. However, there are significant problem when a radio link work
in that diapason – rain attenuation and attenuation in earth-s
atmosphere. Based on statistical rain rates data for Bulgaria, the link
availability can be determined, depending on the working frequency,
the path length and the Power Budget of the link. For the calculations
of rain attenuation and atmosphere-s attenuation the ITU
recommendations are used.
