Continue configuring settings as desired; then click Commands > Reboot to save and activate the settings. Alternatively,
if you want to save the configuration settings to the flash memory but not activate the settings, use the save config CLI
command.
Transmit Power Control
Transmit Power Control is a manual configuration selection to reduce the unit’s output power. The maximum output
power level for the operating frequency can be found in the event log of the unit’s embedded software.
By default, the unit lets you transmit at the maximum output power that the radio can sustain for data rate and frequency
selected. However, with Transmit Power Control (TPC), you can adjust the output power of the unit to a lower level in
order to reduce interference to neighboring devices or to use a higher gain antenna without violating the maximum
radiated output power allowed for your country. Also, most countries in the ETSI regulatory domain require the transmit
power to be set to a 6 dB lower value than the maximum allowed EIRP when link quality permits, as part of the DFS
requirements.
You can see your unit’s current output power for the selected frequency in the event log. The event log shows the
selected power for all data rates, so you must look up the relevant data rate to determine the actual power level.
NOTE: This feature only lets you decrease your output power; you cannot increase your output power beyond the
maximum the radio allows for your frequency and data rate.
See Configure the Wireless Interface to configure Transmit Power Control.
