The work of Marconi in microwave communications

This paper describes the first land and sea microwave links realized by Guglielmo Marconi in 1932. While other researchers were experimenting with sea microwave links in the same period, Marconi´s land experiment was the first successful microwave link over a roughly hilly terrain, and led to the first permanent microwave radio link. Besides the description of the experiment, many photos and figures are included, some of which are extracted from Marconi´s original works.
