An engineer must perform a survey where the target client devices range from standard Wi-Fi- equipped laptops, consumer handhelds and tablets, and low power tracking tags limited to 12 mW Tx power. With which setting should the survey AP be configured?
A. local power 11
B. local power 5
C. local power 14
D. local power 8
Half of 12 mW is 6 mW, so I think B is the correct answer
If surveying at 50% of least capable this would be D. B makes no sense as it’s 25% power of least capable.
Answer B is correct. Local power is NOT equivalent to dBm. So the value is 8 dBm, but is represented by local power 5.
Tx Power
Num Of Supported Power Levels …………. 8
Tx Power Level 1 …………………….. 20 dBm
Tx Power Level 2 …………………….. 17 dBm
Tx Power Level 3 …………………….. 14 dBm
Tx Power Level 4 …………………….. 11 dBm
Tx Power Level 5 …………………….. 8 dBm
Tx Power Level 6 …………………….. 5 dBm
Tx Power Level 7 …………………….. 2 dBm
Tx Power Level 8 …………………….. -1 dBm
