Seems like the best setup "on the market" would be 4x A5-90s.

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.
