Regulatory Bodies
The RF portion of the frequency spectrum ranges from about 3 kHz to 300 GHz. Frequencies within the RF spectrum are available because they exist everywhere, but it would not be wise to use any frequency at will. For example, suppose someone decides to set up a radio transmitter to broadcast a signal on 123.45 MHz. Unless other people know about the transmitter’s frequency and have radio receivers that can tune to that frequency, no one will be able to receive the signal. Even further, a frequency might be used by one entity for a specific purpose, while another entity might try to use the same frequency for a different purpose. To keep the RF spectrum organized and open for fair use, regulatory bodies were formed.
