To develop highly reliable fixed wireless links, such as mobile backhaul and fronthaul systems, it is essential to evaluate the link budget under extreme weather conditions. In this paper, we presented a evaluation for links using radio signals at four different carrier frequencies: 75.375, 85.375, 275, 400 GHz. As examples of conditions, focused on storms which can be defined combination high temperature, violent rain, strong winds. A theoretical model was proposed attenuation by wind...
