Configuring Client Radio Transmit Power
The transmit power level of Cisco clients can be controlled by a Cisco wireless infrastructure device.
The client software chooses the actual transmit power level, choosing between the lower of the access
point value and the locally configured value.
To set the transmit power on your wireless device radio, use the
power client
command.
For all 802.11b 2.4 GHz radios, the settings are in mW:
