Is there any issue with ultra high ceilings and Unifi AP AC

Hi,

 

One of my clients has very high warehouse ceilings that are at about 18ft. Is there any issue with blind spots etc directly undernearth or nearly underneath the Unify AP AC.

 

Thanks

Re: Is there any issue with ultra high ceilings and Unifi AP AC

in a previous place i worked we had some original UPA's at about 25-30ft above the ground in a warehouse, we certainly didn;t hear any issues from our users on scanning guns (motorola 9090's), connection to a rather latency sensitive database. so i would expect the AC's to be just as compitent.

There sort of is.  If you study the antenna pattern it goes sideways like a donut.  It does not go downwards too much. If you could suspend it down a little it should help.  But if you have many installed, then I wouldn't worry too much because a more distant one would cover any weak spots.   18ft isn't all that bad either.  But definitely something to keep in mind when planning.

18 feet is not 'high'. I've got a couple running in the same envrionment; no problems. Still, it is advisable to suspend the UAPs off the ceiling and away from the metal trusses a few feet.

Hi,

 

Would there be a problem if I suspended the AP from platform that had metal legs, sort of like an upside down rack. 

 

Thanks

Re: Is there any issue with ultra high ceilings and Unifi AP AC

I agree that 18ft. is not extreme; in a recent very large

warehouse job that has 25ft. ceilings, I suspended the

UniFi radios on plastic conduit; the height above floor

was probably about 15ft.

 

But I have two suggestions: first, suspend the radios as

close as possible to users but not so close that people

or other obstructions are in the way. For a warehouse,

this varies with the content, of course. Second, keep

the radios away from metal structures--including the

beams and lattice-work; suspending can help with that,

even if it's not otherwise needed.

 

I devised a simple but effective suspensions system

that consists of a plastic surface-mount wall box held

by plastic conduit clipped onto a ceiling beam. I

provided a description and photos in another thread.   Dave

I mount mine on 1/2 inch plywood, suspended via threaded metal rods clamped to the truss. @Dave-D is partial to PVC pipe into a junction box. Maybe he'll provide some pictures of that.

[ Edited ]

'flipper', I provided a bunch of photos of all the

materials and strategy I used in another thread.

 

I'm 'partial' to the approach I used because it

uses off-the-shelf inexpensive materials, installs

quickly and doesn't require fabricating anything--

except to cut and glue some plastic conduit. It

only needs a few holes drilled into the UniFi

backing plate with some screws.  Dave

I'm not 100% sure, but I think this might be the thread @Dave-D is referring to with the pics:

Yep, Andrew: thanks for finding it! I didn't know

where it had gone to.

 

Feel free to ask about it, but I think it's fairly

obvious once you see it in action.   Dave

Re: Is there any issue with ultra high ceilings and Unifi AP AC

hi

 

i worked on on project to install about 30 AP in a big warhouse (90 000 sqft) with a kind of very very high ceilling of 80 high.

 

1- do the amount of APS aer enough ?

2- wich product should be the best one for this kind of high or rather the the best way to do the couverage should be on wall (both side of the "rectangular" building) at about 20 feet high or so ?
