Digital Transmission Characteristics on Millimeter Waves

摘要

A new 26 GHz microwave system was developed in order to realize”outage-free”microwave systerns.From the results of the field trial carried out in Tokyo,we found a truncation on rain attenuation for all frequencies affected by rainfall.Finally,it was clear that microwave links with a larger fading margin than the upper limit of rain attenuation became outage-free.
