frequency division multiple access/frequency diversity duplex (MMDS) (FDMA/FDD)

There are various transmission techniques for Multichannel Multipoint Distribution System( MMDS). The FDMA/ FDD method is used to implement wireless duplex connections in the connection area. FDMA/FDD (Frequency Division Multiple Access/Frequency Diversity Duplex) is similar to TDMA/FDD with the difference that it involves frequency slots, as opposed to time slots in Time Division Multiple Access (TDMA). FDMA/FDD is particularly suitable for the transmission of large data packets.
