| SDMA (Spatial Division Multiple Access) |
 |
SDMA (Spatial Division Multiple Access) technology facilitates
simultaneous multiple connections at the same frequency. SDMA
(technology also derived from Adaptive Array Antenna technology)
can be used by the base station to transmit to and receive signals
from a maximum of three user terminals (A, B and C). To eliminate
mutual interference, phase and amplitude adjustments are performed
between each antenna of the base station and each terminal.
For example, for terminal A's connection, signal output to terminals
B and C is suppressed. This makes more efficient use of frequencies
and increases base station capacity as well.
