What is FDD (Frequency Division Duplex)?

Frequency Division Duplexing (FDD) is a method where the transmitter and receiver work at various carrier frequencies. The FDD technique is utilized in 2G/UMTS/WCDMA/LTE FDD mode inside wireless networks where it powers voice and data administrations, and in fixed networks, it is utilized in asymmetric digital subscriber line (ADSL) for data administrations. Frequency division duplexing (FDD) utilizes a couple of frequencies for uplink and downlink transmission independently.
