MIMO antennas in opposite directions

Antenna diversity requires the antenna's to be in close proximity and to cover the same area.

Is this also the case for MIMO?

 

What actually happens when we point 1 (directional) antenna of a 2x2 MIMO radio in the oposite direction of the other antenna? Will this result in a 1x1 area in both direction or simply a broken setup?

What would happen if we point the antennas towards the same area but have a distance of 10-15m (or more?) inbetween them?

Re: MIMO antennas in opposite directions

I asked a similar question a while ago.  I don't think this is really best practice.  You could end up with 'hidden node' problems.

 

As for seperating the antennas, if they are pointed to the same area that should be fine, as long as there are no areas where a client can only 'hear' one antenna.

 

I'm no expert though, so other people may have some ideas.

Re: MIMO antennas in opposite directions

Hehe, thank you for your input. I offcourse realize is't not the preferred setup but that doesn't say it is impossible to do.

Since this spicific application would be for low bandwidth application the hidden node issue shouldn't be too much of a bother.

 

So any (Aruba) expert that knows if this will/should./could work or not?
