4		-In LoRaWAN protocol, the gateway transmit packet use the output power base on the Power Index from LoRaWAN server downlink. for example: LoRaWAN server send downlink with this info "rf_power=14", gatewat got this info and it will search the index for rf_power=14 and use the related rf setting to set output power. In some case, the LoRaWAN server might set the rf-power to a quite low value ( for example 0dB) which is not practical for use. In such case, User can manunal change the rf_power=0's rf settings to a higher power out. Below are the methods.
