what is sdma
Short for spatial division multiple access, SDMA is a satellite communications mode for using data from antenna arrays in wireless communications systems. At the base station, SDMA continually adapts to the radio environment, providing each user with uplink and downlink signals of the highest possible quality. At the network level, this improved base station performance can be exploited to increase base station range. [Adapted from 'Intelligent Antennas: Spatial Division Multiple Access']
