This thing looks great from the inside. I'm just guessing, but the photos i was able to take in Vienna tell some story. now here's my theory: It is very likely this box is built around QCA6335 baseband, which has support 8 (!) phased array antennas. if you look closely, you can see the unpopulated power headers for the QCA6310 (most probably, i was never brave enough to pry the small squares out from their beds) RF stages - the red/black wires, 4 on the top, 4 on the bottom left side. the RF connectors are on the backside, and most probably only 3 of them are populated with the appropriate RF connector.
also, the silkscreen says 60Gx8 which is quite a hint that supports my theory.
i'd like to see real life results with this thing, especially with clients spaced so widely apart, they can connect only to separate antenna arrays.
i love the simplicity of this, love the excellent price point. the only thing i might change here would be to add a 2nd ethernet port, or a NBASE-T so we could later enjoy 1Gbps+ speeds if the modulation scheme will surpass MCS8, but that would surely increase the costs.
