Beamforming



Beamforming is the smart antenna technology  . Beamforming transmits power only in desired direction i.e the power is directed in the direction of user.
In point to multipoint scenario it saves the unnecessary transmission of power.
Interference due to multiple path i.e ISI can be avoided by using beamforming , As antenna transmitsin the direction of user so there is no other path of radio transmission to that user , so no multiple path and so no multiple path interference.
OFDM is also a way to avoid multiple path interference . OFDM infact takes the advantage of multiplepath interference.


Please go through OFDM multiple path mitigation capability to understand about its working.
