FAQ's

What is the difference between FDD-LTE and TDD-LTE?

The key difference between LTE TDD, sometimes also known as TD-LTE, and the frequency division duplex (FDD) version more common today is the spectrum deployment and how the signal is transmitted. TDD technology uses a single channel and a timed signal to separate uploads and downloads. FDD systems have two channels of paired spectrum separated with a guard band for uploads and downloads

Why is TD-LTE better than FDD-LTE?

TDD systems are cheap compare to FDD systems due to requirement of less RF modules such as Synthesizer, Local Oscillators, filters etc. Moreover FDD system requires more power compare to TDD system due to more hardware RF modules. Finally TDD is favorable compare to FDD for advanced antenna techniques such as beamforming and AAS(Adaptive Antenna System) due to channel reciprocity in TDD between the uplink and downlink paths.

What is the major MAC protocol difference between TDD-LTE and FDD-LTE?

MAC layer in TDD system is more complex compare to FDD system, as it has to deal with accurate time synchronization between the systems and more signaling interactions. Moreover because of sharing the same carrier for DL/UL there is more delay (latency).
