Frequency division duplex, FDD, uses the idea that the transmission and reception of signals are achieved simultaneously using two different frequencies. Using FDD it is possible to transmit and receive signals simultaneously as the receiver is not tuned to the same frequency as the transmitter. The other system uses only a single frequency and it shares the channel between transmission and reception, spacing them apart by multiplexing the two signals on a time basis. Time Division Duplex, TDD, is used with data transmissions (data or digitised voice), transmitting a short burst of data in each direction. As the transmission periods are relatively short no time delay is noticed on voice transmissions resulting from the time delays introduced by using TDD.
