2.37.1.4.20 Module-1-Ant-Gain

This item allows you to specify the antenna gain factor (in dBi) minus attenuation of the cable and (if applicable) lightning protection. Based on this, and depending on the country where the system is operated and the frequency band, the base station calculates the maximum permitted transmission power.

If the field is left blank, the default setting defined in the configuration profile of relevant WLAN profile will be used.

Transmission power can be reduced to a minimum of 0.5 dBm in the 2.4 GHz band or 6.5 dBm in the 5 GHz band. This limits the maximum value that can be added to 17.5 dBi in the 2.4 GHz band and 11.5 dBi in the 5 GHz band. Please ensure that your combination of antenna, cable and lightning-protection complies with the legal requirements of the country where the system is operated.

The receiver's sensitivity is unaffected by this.

Example:

AirLancer	Antenna gain	Cable attenuation:	Value to be entered
O-18a	18dBi	4dB	18dBi - 4dB = 14dBi

Note: The current transmission power is displayed by the device's web interface or by telnet under StatusWLAN statisticsWLAN parametersTransmission power or with LANconfig under System informationWLAN cardTransmission power.
