Entènasyonal telekominikasyon Inyon an itilize yon sistèm entènasyonal te dakò pou klase siyal frekans radyo. Chak kalite emisyon radyo klase dapre li yo, metòd modulation, nati modilan siyal la, ak kalite enfòmasyon transmèt sou siyal la konpayi asirans lan.

The International Telecommunication Union uses an internationally agreed system for classifying radio frequency signals. Each type of radio emission is classified according to its bandwidth, method of modulation, nature of the modulating signal, and type of information transmitted on the carrier signal. It is based on characteristics of the signal, not on the transmitter used.
