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.
Transmission power can be reduced to a minimum of 0.5 dBm in the 2.4 GHz band and 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.

-
AirLancer Antenna gain Cable attenuation Value to be entered O-18a 18dBi 4dB 18dBi - 4dB = 14dBi
Note: The minimum of 6.5 dBm only applies to legacy abg radio modules with G-mode wireless LAN.
Note: The current transmission power is displayed by the device's web interface or by telnet under or with LANconfig under .
