Hi all
After replacing a AIR-AP1231G and a WAP200 (which both had external antennae) with cluster of two WAP561, I noticed that Wifi Analyzer (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer) on my android phones shows lower values than before.
Wifi is usable and performance is acceptable when near the AP, but there's some potential for optimization. Less than 10m away and through 2 wooden doors (almost straight line-of-sight to the AP), signal strength drops well beneath -70dBm.
I do have the possibility to move the APs around and mount them flat, upside-down or vertical in different places. However, I'd like to base the optimisation on well-informed guess instead of sheer trial-and error.
I've been trying to find a radiation pattern diagram for the WAP561 (relative to it's shape), like there is for other Cisco Wireless antennae (http://www.cisco.com/en/US/partner/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html) or APs with built-in antennae (http://www.cisco.com/en/US/partner/docs/wireless/technology/apdeploy/7.5/Cisco_Aironet75.html#wp44985), so I could determine the best position and orientation for the APs.
Neither Admin Guide nor Quick Start Manual have a word to say about the characteristics of the internal antennae of the WAP561, the mounting instructions just say that the device can be mounted horizontally or vertically.
Is there another document or reference guide I could consult?
Thanks a lot for your thoughts, comments or pointers.
Marc
