SDMA
These consist of several dipole antennas, and therefore adaptive SDMA can only be used for RFID application at frequencies above 850MHz(typical 2.45 GHz) as result of size of the antennas.
A disadvantage of the SDMA technique is the complicated antenna system. The use of this type of anti-collision procedure is therefore restricted to a few specialised applications.
