489 +* Valid uplink data to LoRaWAN server or IoT server. ( We can't reduce this as they are the data we want)
490 +* Invalid uplink sensor data to LoRaWAN serevr. ( See Filter unwanted packets)
491 +* LoRaWAN Status push or polling data to LoRaWAN server . ( We can reduce this part , see below for discussion)
492 +* System Keep Alive data. ( To ensure the system is more robust, can be disabled)
