AIR AP1832i - Radiation Pattern

[rwasshaug]

Hi,
I'm wondering if anyone here can tell me where to find the radiation pattern for Cisco Aironet Air-AP1832i.
To me, it looks like the illustration is wrong for the Cisco Aironet 1830/1850. At least for 5-GHz.

Thanks.

Looks indeed wrong. I hope you submitted that feedback with the feedback function?

Try this document for a hopefully correct pattern: https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-2/b_Cisco_Aironet_Series_1830_1850_Access_Point_Deployment_Guide.html

Hi
Thanks for reply!
But, I'm not sure if that's the correct pattern.

We have 50 plus AP of the type 1702i. We need to expand the wireless network to cover more classrooms. And according to Cisco, the CAP1702i has been replaced by the AP-1832i.

But the coverage area is very different.
When installing 1702i or 2800 in the ceiling, the area under the AP will get most of the energy. But when installing an AP1850i in the ceiling, the floor above will also get a large part of the energy too. Strange replacement.
I'm only interested in covering the area of the room where the AP is located.
I'm not sure how to interpret the illustration with the radiation pattern for the AP1850i. The illustration confuses me.

One of the things that affect coverage is the TX power level.  Cisco makes the antenna to be close as possible so that folks can swap and have a similar coverage.  So the pattern is very similar, but what signal you gather is affected by the TX power.  If you test using the lowest power and identical channel, then you should see similar coverage.

One thing regarding the graphs, the one for the 1830/50 is upside down. If you look at the two knobs on each AP, that is the wall mounting side. The image for the 1700 shows it mounted to the virtual "roof" while the 1830 shows it mounted to the virtual "floor".

I think you're right. I also suspect that the graphics are upside down.

Thanks!
