BLE and VBLE power settings

What does the sliding power setting in BLE and VBLE equate to?

 

Where can I change BLE and VBLE power settings?

Access Points → Select AP → BLE Settings/VBLE Array

NOTE: Make sure vBLE Engagement is enable under Bluetooth based Location Services in Site Configuration

 

Should I change BLE and VBLE power for all APs?

Only on rare occasions is it nesscary to change the BLE/vBLE power. If needed to change the BLE/vBLE power, for location purposes, it is highly recommend to change BLE/vBLE power for all APs at once if necessary.

Access Points → Bulk Select APs → More (Top right of the page) → Batch Edit → Set Beacon Power (Change via the slider)
