The AP transmit power .
17 dbm = how many milliwatts? 16 dbm = ? 15 dbm = ? 14. dBm = ?
Rule is:
dBm = log10 (mW)*10 or: mW = 10^(dBm/10)
Which means: 0 dBm = 1 mW 10 dBm = 10 mW 14 dBm = 25 mW 15 dBm = 32 mW 16 dBm = 40 mW 17 dBm = 50 mW 20 dBm = 100 mW 30 dBm = 1000 mW = 1W
Is that the lower number will have a better transfer rate?
No, for transmit power, the higher the power, the better the range (or the better the rate at same distance). You're confusing with sensibility, where the lower the value (usually negative dBms) the better. The idea is that receive sensitivity must be higher than transmit power + amplifier gain + transmit antenna gain - distance loss - noise + receive antenna gain.
And 200milliwatts = dBm?
23 dBm.
