MIMO Antennas in Different Directions

    Hello,

     

    Is it possible to have a 3x3 directional antenna system connected to a single AP with each of the 3 antennas pointing a different direction?

     

    Obviously the throughput would be limited to 1 antenna at one time. It would effectively be a single AP with a very strange shaped cell.

     

    Are there any examples of this in the wild?

     

    Thanks

    This is not possible.  All antenna elements must be oriented the same -- same direction and on the same plane.  You need multiple radios, each with their own antennas.  We have a quad-radio AP, the MSR4000, that can do this. 

     

    Please take a look at our Outdoor VRD :http://www.arubanetworks.com/wp-content/uploads/OMWN_VRD_2012-01-04-1.pdf

    I agree with Marcus.  In the very least you'll have 'hidden node' problems with clients.  The only time this would be acceptable is a point to multi-point link, which I'm sure is covered in the guide.

    Thanks for the answers, sounds reasonable
