With a whole bunch of SFPs? ;) Yes the A5-360 does exactly what Gino suggests, and you all have it right that you need sophisticated MAC layer stream isolation or scheduling logic based on downstream traffic demand and physical location (with or without MU-MIMO), which is why external smart antenna logic is going the way of the dodo bird.
In the 360 case it's more stream directing, rather than beamforming in the 90 case where the antennas are aligned and can collaborate to beamform. As you go up in higher order MIMO though, the advantage (beyond more MU streams) is on the AP receive chain where you can use extra antenna chains pointed in the same sector to null out noise. The TX side antenna patterns also get more refined in their patterns to aim at the CPE and create constructive nulls. So while it's super cool to have a bunch of synched 4x4 90's, its even more useful for noise nulling when you move up to 8x8 and beyond in the AP side. There's still a lot of headroom to realize those advantages in the MIMO tech that have yet to be tapped.

The problem was no GPS and none of the radios were synched, hence the problem with the panel. This is the way Xirrus does it today also. The second guys were SkyPilot and they used an antenna switching unit that turned on/off 1 of 8 sectors with GPS handling the timing. They actually had a pretty good idea because it allowed them to use PTP rules in 5.8GHz. This actually worked pretty well, we had radios at 10+ miles which was pretty good for a pair of 45 degree sector antenna. It’s also where I got the idea that OFDM in many cases of NLOS, works better with sectors than more directional antennas. The Mimosa A5-360 is a 4x4 connection with each antenna on a different stream. The higher gain antennas along with the circular polarity means better range and better ability to deal with polarity angular changes in high multi-path environments. It doesn’t help with the s/n ratio other than higher gain antennas but that same gain is applied in all directions so the noise gain comes with that. The beam-steering that everybody uses today is okay but the antennas are low-gain, but they help the f/b ratio so the end result some much range improvement but better s/n ratio. This is difficult to do and there is a speed hit to the AP to do this since only one antenna can be transmitting at a time versus something like Xirrus where multiple radios can transmit whenever. Because you can’t control the clients transmitting like you can with a synched system, there are going to be tradeoffs between a Ruckus type radio and a Xirrus type radio.
