The thing you need to watch out for with Ubiquiti is that they don't support DFS, so the entire U-NII-2 channel space is off limits for 5 GHz.

I know you don't want to hear this answer because of cost but I've had good luck with Cisco for very high density (about 1,000 clients in a packed auditorium actively using the network as they follow along with the presenter).
The thing you need to watch out for with Ubiquiti is that they don't support DFS, so the entire U-NII-2 channel space is off limits for 5 GHz. That's pretty significant because you're limited to 9 x 20 MHz channels or 4 x 40 MHz channels. Keeping the power level down and creating small cells is essential for high density, so with less channels your hands are really tied in that case. Also, avoid the Zero Handoff marketing nonsense they advertise; I'm sure it can work great for a low client residential area but it requires all APs to share a single channel and depends upon coordinating only one active transmitter at a time, so it simply won't scale.
I don't have experience with other vendors at large scale or high density.
I don't think what you're talking about is really high density anymore though. That's just normal coverage. Wireless is a lot more complicated than selecting a vendor, though. If you know what you're doing even Ubiquiti could work decently, but if you don't even a Cisco solution won't save you. You really need to be on top of surveying correctly and having appropriate AP placement and channel distribution.

Hi
We are profiling equipment and design for an expected high user density network of multiple, close nit, residential/hostel units. Its going to be 8-10 buildings with possibly a over 1000 users at any given time. We are looking at Ruckus and Ubiquiti as options to get over the high number of devices we are definitely going to encounter.
How did you do it, and what would you advise for product and layout?
Thanks in advance!
