time division multiple access/time division duplex (TDMA/TDD)

Time Division Multiple Access/TimeDivision Duplex (TDMA/TDD) is one of several techniques for transmission in the access area that is also used in MMDS (Multichannel Multipoint Distribution System) and Local Multipoint Distribution Service

(LMDS). The TDMA/TDD technique differs from the TDMA/FDD technique in that only one frequency is used for the downstream and upstream channels, and within that the time slots are time-divided for the outward and return channels. The disadvantage of this method is synchronization.
