Electromagnetic Spectrum has all the ranges of electromagnetic radiation. Radiation is the energy that travels and spreads out, as it propagates. Of all the waves, Microwaves are a special type of electromagnetic radiation that is used in many ways from cooking simple popcorn to study the nearby galaxies !!!
There are a wide variety of applications for Microwaves, which are not possible for other radiations. They are:
For long distance telephone calls
In Outdoor broadcasting transmissions
In broadcast auxiliary services
Remote pickup unit
Direct broadcast satellite (DBS)
Personal communication systems (PCSs)
Wireless local area networks (WLANs)
Cellular video systems (CV)
Automobile collision avoidance system
Fast jitter-free switches
ECM/ECCM (Electronic countermeasure) systems
Spread spectrum systems
Garage door openers
Police speed detectors
Identification by non-contact methods
Cell phones, Pagers, Wireless LANs
Satellite television, XM Radio
Global Navigation Satellite systems use microwaves.
Global positioning system GPS
Radar uses microwaves for detection of range and speed of the target.
Air traffic control
Navigation of ships
For Minesweeping applications
Speed limit enforcement
Military uses microwave frequencies for communications and for the above-mentioned applications.
Cosmic microwave background radiation can be marked.
Powerful waves in the universe can be detected.
Many radiations in the universe and earth’s atmosphere are detected.
