Thanks very much for the feedback!
The Maps you are referencing currently are predictive and the practical use is to be able to see a general heat map prediction to help troubleshoot problems while being able to see where APs are and what their coverage most likely looks like based on the power settings of the AP (this can help you visualize problems with specific APs being on the wrong channel or being set to too high or low of a power setting. There have also been major enhancements to the power settings to more accurately reflect AP transmit power on these maps in version 2.8.0 and version 2.9.0.
You are current in that they currently do not allow the same sort of use as real prediction software and site surveys. They are simply a quick way to visualize coverage when troubleshooting problems directly from vWLAN. Several major features have been added in version 2.9.0 and are planned for subsequent releases that offer the ability to continue enhancing the use of these maps such as AP/Sensor mode (Dual mode) which allows APs to scan off-channel while still servicing clients and Dynamic RF which can help select optimal radio settings.
I am planning to move this to our Feature Request section so we can consider this feedback for future releases.
