If you recall, not too long ago Cisco did come out and say that ceiling mount is strongly recommended- to the point of dropping wall mounting from the text in their documentation.
I believe RRM assumes a ceiling mount for whatever it is worth to the enigmatic "algorithm". -Lee -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Procyk, Ian Sent: Monday, November 09, 2009 2:30 PM To: [email protected] Subject: Re: [WIRELESS-LAN] 1140 Cisco APs Kristina, Also be aware of the fact that to mount on a single gang electrical box, you will likely need another adapter plate (or access to a drill press if you want to roll your own). The 1142 brackets no longer have the X-Y holes that the 1131 brackets had, which made the 1131's so nice and easy to mount up against the wall, with only the stuff supplied in the box. We are finding that the current architectural trend on campus, is one that is shying away from t-bar ceilings - hence our need for the alternate brackets. In many cases we are back to open and exposed ceilings with cable tray and pipe. Often an acoustic baffle, made from what can only be described as "pressed wood shavings" is hung from the ceiling as well, these don't like to be drilled or bolted into...

From the results (same location, 12 feet), the coverage of vertical mounting (on the wall) and horizontal mounting (under the ceiling) are almost the same. Please consult with Cisco about the mounting position of 1140 AP; I think both of them are suitable for 1140.

We currently have 22 WiSMs and approx 1100 APs (1240s and 1230s). Currently there are two Cisco flavors of APs the 1252 and 1140. We are shying away for the 1250 series because of the power draw limitation with our current PoE switches. We don't want to start using injectors again or buy all new 3560e switches! However the 1140s were designed to be hung from the ceiling and we only hang wall mounted APs. Has anyone else installed 1140s on the wall, and if so, did you have to change your design methodology?
