From the information in Location manager, it appears that the WLSE 2.5 assumes that all my access points are using the Omnidirectional (rubber duck!) antenna, and thus the radio coverage is more rounded.
We use Patch antenna to direct the radio coverage into our building to 1)provide better coverage and 2)reduce signal leakage.
Unfortunatley, it appears that the radio coverage assumption also prevents accurate radio measurements and so Rogue AP's are not pinpointed properly on the map.
The building measurements have been entered correctly into Location manager, so I can only summise that the antenna selection is the cause.
Are there any workarounds for this problem? Has anybody else come across this?
