The clarity is provided by the Antenna radiation patten. Which also highlights a shortcoming of the "saucer" shape of the 1142. The pattern for each spectrum is a lopsided circle viewed from above. Lopsided depeding on which side of the ap each radio is on becase the central body of the ap itself blocks each radio(and there's no easy way to tell which way the antenna are oriented). This skews your coverage, although the effect is minor, it's not what I prefer to see in an "omni" design. The 1142 also is definately not designed for wall mount. It's vertical plane is flattened (as expected for a ceiling mount ap). As well they don't offer a vertical mount (that I'm aware) of for the 1142.
Feel free to ask your Cisco SE For the radiation pattern spec sheets for the 1142. They're also available on the cisco website but are poor visual quality. There should be very little reason for ever mounting an 1142 in a vertical orientation. Unless you just really enjoy buying more Cisco APs to make up for the oddly shaped and sized coverage. --- Justin Hao j...@austin.utexas.edu University of Texas ITS - Networking On Apr 11, 2010, at 8:36 PM, "Lee H Badman" <lhbad...@syr.edu> wrote: > To your point, Justin- in my mind I still don't feel that Cisco has > done a good job of providing clarity about the topic of wall- > mounting.
