Max mounting height for 3802i AP

JaganV — Mon, 05 Jul 2021 17:53:36 GMT

Hi guys,

Anyone have info on what is the max height an AP can be mounted?

Could not find this info on any doc.

I am using 3802i (internal antenna) type APs and will be installing in a high ceiling environment.

Thanks.

Get a wireless site survey done.

Leo is right.... get a survey done so that you know what you are getting. Environments are different along with how one designs for overlap and density which can affect your overall RF.

As Leo said get a site survey done. You will generally find that internal APs mounted above 3-4m will have issues with signal strength to/ from the devices

Max mounting height for 3802e AP + AIR-ANT2524?

Hi,

ok, so having ascertained that from experience an indoor AP with integrated antennas (3802i) should generally be mounted at a maximum height of 3-4m.

Here: 1700/2700/3700 Access Points Deployment Guide or here: 4800 Access Point Deployment Guide it's specified:

"When practical position the APs as close to the users as possible ideally suspending the AP-4800 12-15 feet (enterprise ceiling height) when practical to do so. See section above on electrical box mounting for pictures."

"If the AP is 30 feet in the air, (that is an additional 30 feet farther the signal has to go, “best case”). When configuring coverage for aisles, try to use directional (Patch) antennas on the wall and shoot down the aisles; or use low-gain Omni-directional antennas on the ceiling (such as dipoles) or units with integrated antennas as high gain omnidirectional antennas tend to have more nulls.

In your opinion/experience, could we increase this height using APs with external antennas (3802e) combined Low-Gain Dipole Antenna like AIR-ANT2524? and what could be an optimal height before choise to use a patch antenna?

Thanks
