I'm not sure if this all-in-one game is going to work. IMO, Unifi's hardware apart from their Wireless offerings is limited compared to other players in a similar price range. They should stick to what they're best at, which for me is their Wireless range and build around that.

In our case, we ended up using Mikrotik devices for our physical layers and Unifi as our APs. So far, the performance of the Wifi devices is excellent (though tuning high density configs was a bit of a pain), and the Mikrotiks give us exceptional control over the behaviour of the network topology.

Playing to the strengths of each vendor was the way to go for us. Worked out way cheaper as well.
