Demand Assigned Multiple Access

Encyclopedia : D : DE : DEM : Demand Assigned Multiple Access

Demand Assigned Multiple Access (DAMA) is a technology used to assign a bandwidth to clients which don't need to use it constantly. It allows utilizing of one channel (frequency band, timeslot, etc.) by many users at different times. This technology is mainly used by small clients, as opposed to PAMA (Permanently Assigned Multiple Access).

DAMA and PAMA are related only to bandwidth assignment and are not to be mixed with the Multiple access methods intended to divide a bandwidth between several users at one time, which include FDMA, TDMA, CDMA and others.

DAMA is widely used in satellite communications, especially in VSAT systems.
