3	3	In LoRaWAN protocol, the gateway transmit packet uses the output power base on the Power Index from the LoRaWAN server downlink. for example, the LoRaWAN server sends a downlink with this info "rf_power=14", gateway 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 cases, the LoRaWAN server might set the rf-power to a quite low value ( for example 0dB) which is not practical for use. In such a case, the User can manually change the rf_power=0's rf settings to a higher power out. Below are the methods.
