Microwave Data Transmission
Microwaves are useful for short-range, high-reliability data links.
Satellite communication and control are generally carried out at micro-
wave frequencies. The microwave region contains a vast amount of spec-
trum space, and can hold many broadband signals.
Microwave radiation can cause heating of certain materials.This heating
can be dangerous to human beings when the microwave radiation is
intense.When working with microwave equipment,care must be exercised
to avoid exposure to the rays.
The illustration shows a simplified block diagram of a microwave
transmitter and receiver, including the antennas. The antennas are highly
directional and must be aimed at each other with a line of sight between
them. Microwave data transmission is useful in robotic systems in which
a line of sight can be maintained between machines while they are in
communication. Compare LASER DATA TRANSMISSION.
