The main reason is that, as we already know, different frequencies encounter different channel effects . Thus, as TDD fosters uplink/downlonk on the same frequency band, the result is better channel estimation as compared to FDD. FDD in contrast, utilizes different frequencies for each transmissiom direction.
Read moreWhat is the advantage of FDD?
Following are the benefits or advantages of FDD: ➨It is proven technology for voice traffic . It is designed for symmetric traffic and do not require guard time like TDD. ➨It uses paired spectrum on continuous basis for both the directions and hence it can achieve higher rates for similar distances as TDD system.
