It is in the ceiling of a building in a tube not too tall but enought to deliver WiFi all around with a 5/7 dBi collinear antenna. In a sealed plastic box painted with anti uv rays ink. So it is not very easy to access but is all ready for service if some problems comes. I'm just powering it with self made PoE. It uses two pairs of the UTP to deliver near 14V in a less than 50 meters UTP wire. In the apartment of a friend where is installed there are a ethernet switch (with the PoE supply) and using a self made wall transformer (3,5 Amp, 14 DVC). Someday it not worked anymore. We just get the key to go to the celing of the building to service the AP. Later we noticed that the AP worked perfect. But installed in the place the leds just bright not enought. That just was weird. Not really, the problem was in the transformer. The capacitors just becomes unstable (they was a little inflated). So the AP just be there for near 3 years working all the day and I just lose my time going to service it with no need. Lol, that just showed me what some problems are not just the AP itself instead are related with the external power supply. Specially in PoE environments. Now this AP is still working very well but I need to improve more the transformer (I need to put still best capacitors). So, don't waste money in inexpensive things, just buy powerful enought transformers. And if you are capable: DIY. Because some transformers what comes with equipment are constructed at limit of the requeriments. Bye bye I too have an AP installed far away from me.
