FDD
(Frequency Division Duplex)
Frequency Division Duplex (FDD) is a method used in telecommunications to enable simultaneous two-way communication by allocating separate frequency bands for uplink and downlink transmissions. FDD is commonly used in cellular networks, such as LTE and 5G, to ensure efficient and interference-free communication.
By using distinct frequency bands, FDD allows devices to transmit and receive data simultaneously without signal overlap. This makes it ideal for applications requiring real-time communication, such as voice calls and video streaming. FDD is often compared to TDD (Time Division Duplex), which uses the same frequency band for both uplink and downlink but alternates transmission times.
