AP Placement

Hi Everyone

I have a warehouse that I want to cover with Cisco AP's 2802i

The space is about 2500 square meters(8202 square feet), and about 7 meters highs(23 feet high)

Any suggestions on how many AP's

Thanks!

You can’t really guess on this. What determines this is the racks, products in the racks, devices that need to associate to the wireless, where you can mount AP’s and it external antennas, etc. a site survey by experienced engineers would determine the best location for AP’s and or external antennas which then would result in how many AP’s you need.

If the client wants to get this done right, then get a wireless site survey done.

Wouldn't be using 2800i with heights above 4m

As stated a wireless survey is required as a warehouse is a complex wireless environment. Need to take into account racking, and other attenuators in the environment, and if you get it wrong it can kill production.

Take a look at the presentation in this post i did at the Ekahau WiFi Day:

Hi Andrews

Thanks for your answer,

can i ask why they shouldn't be implemented above 4 meters, although we will connect it with external Antenna (CISCO SYSTEMS AIR-ANT2544V4M-R) as the image below shown

Experience.
Experience is a very painful teacher.

This is why you need a site survey. You mentioned to use 2802i, that model can’t use external antennas, the 2802e can. Now there is a best practice with height using internal antennas and also a manufacturer external antenna recommenced height. I have seen internal antennas work at a very high mounting location but is that the best way, no it’s not. Since you picked out your ap and antenna, you should invest in a site survey by an experienced company.
