SDMA

(Spatial Division Multiple Access) A satellite communications method that transmits within the same frequency to different receiving zones on earth. It takes advantage of the narrow beams that can be transmitted by the satellite to dish antennas and allows channels (frequencies) to be reused over a large number of geographic zones. Contrast with FDMA and TDMA.
