    I am creating a heat map in Airwave and just want to know about proposed placement of new AP's.  what is considered an OK dB?  is there a chart to associate dB with signal strength?

    An ideal signal to target is -65 throughout the area (make sure this is on 5GHz....I usually remove 2.4GHz from the heatmap so not to misinterpret).   This will provide clients with a high quality link (barring other interferers) throughout.     You can levarage this VRD to help you along (it is for 802.11n, but still applicable).

    so lower the -dB the better (signal)?

    Well, technically no...

     

    Since the values are negative, you want the number to be higher as far as value goes.

     

    Think of it this way; the closer to 0dBm the better the signal

     

    Take a look through this user guide, it's pretty usefull when starting out with VisualRF.
