A communication system that utilizes the radio frequency band spanning 2 to 60 GHz. As per IEEE, electromagnetic waves between 30 and 300 GHz are called millimeter waves (MMW) instead of microwaves as their wavelengths are about 1 to 10mm.
Small capacity systems generally employ the frequencies less than 3 GHz while medium and large capacity systems utilize frequencies ranging from 3 to 15 GHz. Frequencies > 15 GHz are essentially used for short-haul transmission. Microwave radio communication requires a clear line-of-sight (LOS) condition. Radio LOS takes into account the concept of Fresnel ellipsoids and their clearance criteria.

Thank you for this information. I've heard of microwave planning, but I never really knew much about it. My nephew is studying microwave engineering, so I thought now would be a good time to learn more about it.
