| electromagnetic spectrum |
The entire range of frequencies of electromagnetic radiation from zero to infinity which measure electromagnetic energy. The Radio spectrum (less than 300 GHz bandwidth) is divided into subsets of various bandwidths which are identified by their frequency characteristics. For example, the Ku-band subset includes those frequencies of the radio frequency (RF) spectrum between 10.7 GHz and 17.8 GHz while the C-band subset includes those frequencies between 3600 MHz and 7075 MHz.
