NationMaster - Encyclopedia: SDMA

SDMA or space-division multiple access is a channel access method which enables the use of the same frequency (for instance on GSM systems) at the same time in different spaces (cells). This means, however, the cells can't be next to each other. Cells using the same frequency are typically separated by two cells.

What is spatial division multiple access? - a definition from Whatis.com - see also: SDMA (339 words)
	Spatial division multiple access (SDMA) is a satellite communications mode that optimizes the use of radio spectrum and minimizes system cost by taking advantage of the directional properties of dish antennas.
	In SDMA, also known as SDM (spatial-division multiplex), satellite dish antennas transmit signals to numerous zones on the earth's surface.
	SDMA requires careful choice of zones for each transmitter, and also requires precise antenna alignment.
