Abstract :
To assist in meeting the explosive growth expected in telecommunications in the next twenty years the Post Office and the Science Research Council have begun what is probably the largest microwave-propagation study yet to be mounted anywhere. This project could have a major influence in opening up the 10¿100 GHz range of the radio spectrum (wavelength down to 3 mm) to new microwave telecommunication system use. As frequencies rise about 10 GHz, transmissions are increasingly affected by the weather and the object of the study is to find out just how radio transmissions at these millimetric wavelengths are affected and what can be done to avoid disruption of service. This article describes the broad details of project.
