AP installation height ?

Any suggestions about the installation height (min / max) above the floor (or other baseline locations) for the typical ZF AP?

And specifically:

Indoors (zf7982) >

Outdoors (zf7762) >

Good question, I wondered too. I have a market that has a very high attic above it. I can mount the AP on the attic floor or any point higher for about 40 feet up.

It's not a clear cut answer. What is typical?

In the office, hotel or similar ceiling is not more than 3m tall and that's perfect. In warehousing ceiling is higher and it depends on what kind of things are in the warehouse. Maybe you want to minimize cell coverage and you would not install APs on the ceiling, but maybe you need to. WLAN design is not trivial. You need to try, get experience and reading some books certainly doesn't hurt.

I have installed an AP 40m up and walked 60m away from it and still had good connection.

Primoz points are important. All installations will vary with environment. An
outdoor 7762 is typically mounted on light poles or outside 2nd floor of bldgs,
with dome down. An indoor 7982 can be ceiling mounted (over wall mounts),
and can also be placed on top of book cases or filing cabinets, in a one-story
office building, and still radiate good lateral coverage. Mounting on the ceiling
of two-story office buildings may radiate above and below sufficiently. But a
pre- and post-installation site survey, measured to your desired data rates, is
always the best advice to determine AP coverage.

Maybe if you give us a specific problem you wish to solve, we could help you better.

Where will the APs be placed? What kind of environment? etc.

I have various classrooms that vary in ceiling height from 3m to 15m.

Some classrooms ceilings vary from 3m to 9m within the same room.

Well with classrooms you'll have more issues with capacity than height. I'd say 8m should be just fine. Classrooms are sometimes slanted, so you need to consider that also, but probably it's not that big of an issue. How big are they and how many people fit in?

Are APs deployed yet or are you still in talk where to put them?

Yes, some are slanted: 3m to 9m

You say: 8m but is that optimum?

Typical class size range from 30 to 600 persons.

Deployment: 10% complete. Still pondering, hence this forum post and open Ruckus case.

Well for classrooms that have 30 clients, I'd say you can cover more with 1 AP.

For 600 you need to start asking your self, is everybody going to access it at the same time. I've had a 2000 user deployment at a conference hall. I used 3 7372s, but there were only 300 users at one time connected. That's under 20%, but that was a conference. One 7982 can take 300 users but it depends also on what are users doing with their clients? Will they all require a connection at the same time for some video streaming or just some browsing and e-mail and stuff?

Be careful, as you can get into more problems with using too many APs at one location than you think you'll solve. It's so many things to consider.
