FDD(Frequency Division Duplex)，分頻雙工。FDD is employed in radio systems to provide an uplink and downlink radio channel between the network and the user. It uses paired spectrum - one frequency band for the uplink, one frequency band for the downlink and is much more efficient in the case of symmetric traffic.[1]

The frequencies separated by a duplex spacing. Users tune between the uplink and downlink frequencies to transmit and receive respectively.[2]:-:RF傳輸雙工方式。
