Folks,  I'm mostly through with the wiring and installation of access points in the church I've been working on.  I've got two rooms left in which to install access points.

The first is the "fellowship hall".  It's about 30' x 50'.  It has a ceiling that is more than 20 feet high, and beyond cabling issues, it's basically impossible for me to reach the ceiling with the equipment I have.

The second room is the sanctuary, about 40' x 60', and again, the ceiling approaches 30 feet... getting to it is nigh on impossible without expensive equipment rental.

Therefore, in each of these rooms, I'm going to mount the AP on a wall.  For the fellowship hall, it will be about 10 to 12 feet off the ground and in the middle of the 50' wall.  For the sanctuary, the AP will be at least 15 feet off the ground and mounted in the middle of the 40' wall.

Now to the question:  These are ceiling mount devices but TP-Link also supplies wall mount kits as well. I don't care about the signal on the other side of the wall on which these devices will be mounted (handled by other AP's).  Should I simply mount these devices vertically on the wall with the supplied kit or should I use a bracket and mount them horizontally as though they were mounted on the ceiling?  I can't find anything that shows the coverage pattern for the EAP620 HD.

Hope that makes sense.  Thoughts and insights are appreciated.
