Propagation of Microwaves Thought Atmospheric Environment

Wireless microwave systems tend to have high availability figures, but at the expense of the ability to operate at higher data rates. A quality of free space communication depends on atmospheric conditions. It is shown that microwave attenuation reacts sensitively on changes of changes of hydrometeo...
