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

Intelligent Antennas: Spatial Division Multiple Access (PDF) Antennas collect radio frequency energy from space for reception purposes and distribute energy into space for transmission. To date, they have been the most neglected of all the components in personal communications systems.
