DAMA - Computer Definition
A wireless access technique used extensively in satellite systems. DAMA is a variation of frequency division multiple access (FDMA), which assigns Earth stations specific uplink and downlink frequencies within an allotted range licensed for use. DAMA assigns available channel capacity to an Earth station from a pool of bandwidth, on demand and as available in a first come, first served manner.The Earth station transmits request to send (RTS) messages to the satellite until it responds with a clear to send (CTS), at which time the message transmission ensues. DAMA allows several carriers, and perhaps a great many Earth stations, to share a given frequency band, as needed. See also downlink, FDMA, and uplink.
