SDMA controls the radio signal for each user in space using spot beam antennas. In this technique, different antenna beams are generated to cover different areas of the cell thus serving users through these beams on the same frequency using TDMA or CDMA.

Space-Division Multiple Access (SDMA) is a channel access method based on creating parallel spatial pipes next to higher capacity pipes through spatial multiplexing and/or diversity, by which it is able to offer superior performance in radio multiple access communication systems

SDMA Space Division Multiple Access is a channel access method used in radio telecommunication systems such as mobile cellular networks. SDMA is based on the creation of parallel data streams travelling from multiple antennas (also known as spatial multiplexing).
