Fast forward and Ubiquiti introduced a set of 2nd generation products, the UAP AC Lite, UAP AC-LR, and UAP AC-Pro. They went back to Atheros, the chipset vendor that they were more comfortable with, and they have more experience. The product shows it. Power requirements are down, so they offer 802.3af PoE on the UAP AC-Pro. The other units include their non-standards compliant passive PoE, which will mean you need to either use them with a Ubiquity switch to provide power, or the little injector bricks that they include. I'm really a fan of standards compliance, so I would think twice before going that route.
