Time-Division Duplex. A means of providing bidirectional communications in digital wireless networks, such as cellular networks.TDD typically is used in conjunction with frequency-division duplex (FDD), with the forward and backward time division multiplexed (TDM) channels riding over separate frequency channels. Further, the time slots are staggered so the frequency-specific transceivers are not asked to transmit and receive at the same exact moments in time. See also cellular, digital, FDD, TDM, time slot, and transceiver.
