Effects of precipitation and reflections from a snow covered ground measured at 40 and 60 GHz on a 600 m experimental link in Norway

Millimetric radio systems are becoming increasingly more important to communication services. The applications clearly cover fixed radio link services both in the trunk and regional or local networks, for example as backbone and feeder links for cellular radio. Recently many new applications are beginning to take place, such as cellular systems for access to broadband services. However, the use of millimetric bands uncover a need for better understanding of propagation effects and, for example, validation of statistical attenuation prediction methods. This paper present precipitation attenuation measurements at 40 and 60 GHz taken close to Oslo from the summer periods of 1993 and reflections from a snow-covered ground during a period of the spring 1994.
