What transmit power set at?  What band (2.4 or 5) are we referring to?  How far is the machine from the AP and what is in between them?   You probably need to add another AP
  closer to area of interest

Thank you for your reply. Creating RF profile is one of ways for increasing signal.
But really there is another simple way to do it. In wlc gui, default is " 1 ", we can change to " 6 " as max. But i cannot find it in gui

Transmi power set is also option?

Please see the below. I found out something. When in Assignment Method change to Custom, we can change Tx Power Level. but I do not know under the same C9800, why we can only change it at AP9117, not AP9130, which cannot be changed to Custom due its grayed out in there
