Hexadecimal – 16 digits (0 1 2 3 4 5 6 7 8 9 A B C D E F)
Count up to the last digit, then return to zero and increment the next column to the left
Example: 0x61
Decimal – 10 digits (0 1 2 3 4 5 6 7 8 9)

General
- Reduce the power level on the AP to half the expected client max. power value. Turn off Dynamic Transmit Power Control (DTPC) for the survey.
