Transmit Power
Note the following about the transmit power output specified in these tables:
• The output power is measured at the Hirose connector with an RMS (root mean square, or
average) power meter.
• Taiwan regulatory limits for maximum transmit power: 18 dBm for 802.11b, 16 dBm for 802.11g,
19 dBm for 802.11a
• The maximum transmit power is determined by both (1) the 10% packet error rate at 3 dB above
the 802.11a or 802.11b/g rate dependent sensitivity and (2) the 802.11a or 802.11b/g spectrum
mask limit.
• The maximum transmit power may be lowered by regulatory (FCC, ETSI, etc) EIRP (effective
isotropic radiated power) limits.
