Hello Everyone,
The first practical application of microwaves in a communication system took place more than 80 years ago. In the 1930s, an experimental microwave transmission system was used to connect the United Kingdom with France—bridging the English Channel without cables. In the 1950s, AT&T built a 10-channel microwave radio relay system in the United States that was capable of carrying 5,400 long-distance calls per channel, supporting a total of 54,000 simultaneous callers. The emergence of television provided another opportunity, as network broadcasting was relayed to local affiliates across the country. In the 1980s, analog RF systems began giving way to more efficient, higher-capacity digital systems to accommodate rising traffic demand. Even then, microwave networks typically provided long-haul communications—but all that was to change with the development of another ubiquitous consumer RF technology: the cellular telephone.
