    Hi

     

    Does we have horizontal & vertical polarization techniques in aruba(as ruckus has).....if not how do we tackle poralization issues?

    mohan007,

    I am talking about Horizontal & Vertical Polarization. If AP is having only horizonal antenna, and receives a vertical signal there will a loss of signal received by AP, as AP has a horizontal Antenna. Normally i have also heard of AP which has dual polarization enabled!

     

    Does Aruba has these features.

    All outdoor radios and antennas support dual/multiple polarization antennas

    Indoor radios at Aruba do not

     

    Why

     

    Because indoor polarization is of limited beneift due to reflections and can actnually impair the operation of Transmit Beamforming and MU MIMO (as we move towards Wave 2)

     

    In addition , the use of directional antennas indoors can negatively impact MIMO, Tx BF, and MU MIMO
