Error performance and availability are representative parameters featuring digital fixed wireless systems. As far as the propagation path characteristics are concerned, rain attenuation predominates at frequencies above about 17 GHz, while multipath distortion predominates at frequencies below about 10 GHz.
For this reason, digital fixed wireless systems should be mainly designed in terms of unavailability at frequencies above 17 GHz and error performance at frequencies below about 10 GHz, while in the range 10-17 GHz both objectives should be considered.
