I have been using these devices in the office for many years. They're above the false ceiling and I'm still getting 5 bars! I had a boiler room set up - in the attic of a large house - PoE made installation easy and the range of this device was perfect - all the way down the stairs - through all that wood and steel - there were still 4 lanes. The unit is pretty basic - you get a mounting bracket, screws, an ethernet cable and a few clips to install ceiling tiles - that's it. Add a TP-Link PoE power adapter and you're done!
