What Is The Difference Between Lte Fdd And Lte Tdd? |
|
Answer» The difference lies in the LTE frame structure in both the FDD and TDD versions of the LTE. In FDD there will be pair of frequencies assigned in the downlink and uplink directions and hence transmissions from multiple subscribes can HAPPEN at the same TIME but on different frequencies as mentioned.In TDD, ONE single frequency will be used at different time instants by multiple subscriber terminals (UEs). Both frame versions of LTE will have 1 ms sub-frame duration and 0.5 ms slot duration. The difference lies in the LTE frame structure in both the FDD and TDD versions of the LTE.
