FDD vs TDD

FDD stands for Frequency Division Duplex, and TDD stands for Time Division Duplex . Both FDD and TDD are two spectrum usage techniques, both forms of duplex, used in mobile or fixed wireless broadband links.

Theoretical peak throughput in case of FDD is clearly better than TDD . TDD has less capacity to accommodate user data and traffic in radio frame compared to FDD.

LTE and 4G systems use FDD or TDD depending on band .

FDD deployments provide greater coverage than TDD Mobile devices in a Frequency Division Duplexing (FDD) system transmit on a continuous basis, which enables devices to achieve cell edge rates farther from the base station .

FDD (Frequency Division Duplex ) separates uplink and downlink and has seamless interoperability with TDD. Our Massive MIMO implementation will directly enable today’s FDD devices to benefit from beamforming.
