I agree with this model, it works better in ceiling mount. I'm talking about the AP-300, not AP-310.
Check my Ekahau captures:
This one is ceiling, strange omni (it emits strong towards the floor, so the N-1 floor will receive a lot and the radiation is weird)
Now on the wall :
It looks like a patch !
Traditionnally, omni access point mounted on wall would look like your capture, but this one (AP-305) looks like a patch antenna, it is weird ! It means that it is complelty suitable to be mounted on wall, which is strange since it is said to be optimised for ceiling.

Hi Ipic,
Image an square that 100x100meter and put an Aruba AP-315 in the middle.
When placing it on the ceiling your cell looks like this:
When placing it on the wall your cell looks like this:
With placing it horizontal on the ceiling your get a better cell size / coverage area.
Hope this helps…

Hey guys,
Thanks for yours replies.
I know how it can be awful to put AP on wall, i checked multiples times with Ekahau on adjacent floors and i saw that AP leak clearly towards its floor and its ceiling.
I think that the optimal placement/orientation for an access point also depends strongly on its antenna pattern. We can see that AP with integrated patch antenna have antenna patterns where we can clearly see that they emits more in front of them.
With this one https://www.arubanetworks.com/assets/ds/DS_AP300Series.pdf , check the page 6. If i read it correclty, the access point emits more in front of its than on its side (at 180°). However, the datasheet tells us that the AP is optimized to be mounted in the ceiling, why ? It should emits more on its side !

If you have multiple floors, it is awful as you put a lot of 'leak' to the floor above you, which you don't have if you mount it on the ceiling.
The recommendation to mount the APs on the ceiling would mostly apply when you mount multiple APs, and even more if you have larger floors and multiple floors. For lab, it is fine to put the AP on the table; and if you have a single AP for a smaller area, the exact mounting is not as critical. As Marcel mentioned 'it depends'.

Hello,
All wifi specialist journalist and blog writer tell that ceiling mounting is way more optimal than wall mounting. It is clear that they are right when we check the antenna pattern plots of most access points.
But i just checked the AP-300 Aruba's AP, and it seems that they emit more power in front of them than on their sides :
Antenna pattern plots : https://i.imgur.com/yI2R6I2.png (the Azimuth is pure omni)
According to this plot, it is not an awful thing to mount them on a wall. Oddly, the 300's datasheet tell us that they are optimized to be mounted on the ceiling https://www.arubanetworks.com/assets/ds/DS_AP300Series.pdf .
What do you guys think about this ?
Thanks
