Microwave communication is ubiquitous in the modern world, with electromagnetic waves in the tens of gigahertz range providing efficient transmission with wide bandwidth for data links between Earth-orbiting satellites and ground stations. Such ultra-high frequency wireless communication is now so common, with a resultant crowding of the spectral bands allocated to different communications channels, that interference and electromagnetic compatibility (EMC) are serious concerns.
