What is the frequency of Demand Assigned Multiple Access communication?

Demand Assigned Multiple Access (DAMA) communication systems typically operate within specific frequency ranges that can vary based on the application and technology used. In military communications, DAMA systems are often associated with satellite communications, which typically work in the Ku-band (12-18 GHz) or the Ka-band (26.5-40 GHz). Given these common applications and their operational ranges, the answer "None of the above" is accurate. None of the mentioned specific frequencies correspond directly to the typical operating frequencies for DAMA, particularly in the contexts commonly used by military systems. Therefore, selecting "None of the above" reflects an understanding of the characteristic frequency ranges associated with DAMA communication systems.
