When I look at the RF pattern for the Cisco 1532i AP, it doesn't look right. When using Ekahau Site Survey, I only get the advertised pattern when tilting the AP 90 degrees; essentially having the AP face the ground, not running vertical like the image below. In fact when I have the AP running vertical (flat against a pole for example), the pattern almost has no back lobes and looks exactly like a patch antenna.
I found a presentation that backs this up. See below;
Can somebody shed some light as to which way the AP should be mounted to get the best omni coverage? And are the patterns shown above, the best I will get for a 1532i? An 'AP on a stick' survey is not in scope for a project I am working on so I can't test in the real world.
Would love to hear peoples thoughts, or know if anyone has had experience mounting them each way.
