Microwave Networks By Greg Chislett
How They Work • Microwave radio relays transmit both digital and analog signals. Radio waves are exchanged between two points using directional antennas to create a point of contact.
How They Work(pt 2) • Microwave networks are formed when multiple chains of microwave radio relays are set up. Because all of these relays occur within "lines of sight" there is only a very narrow area that the radio wave passes through.
How They Work(pt 3) • Antennas tend to be installed at high elevations, so as to avoid obstacles, because each antenna needs to broadcast long distances very accurately.
Uses • Microwave networks were originally popularized in the 1950's as a way of transmitting long distance calls, as well as television signals between continents.
Uses(pt 2) • The microwave network system was ideal for these purposes because it could transmit large amounts of data reliably across long distances.
Uses(pt 3) • Currently they are used more for portable radio operations, as they have low operating costs, are efficient, and the operator has direct access to the antenna.
