488 488  
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)
493 -* Auto update ( Software auto update, can be disabled)
311 +For this case, by default, the gateway will uplink self-status to the LoRaWAN server per the 30s. the users can adjust the interval time.

501 -* Uplink self-status to the LoRaWAN server every 30s. the users can adjust **Keep Alive Period** as below
502 -* Check LoRaWAN server status every 5 seconds to see if there is valid downlink command to sensors. We don't provide WEB UI option to modify this time, because the modify of this settings will lead to fail on OTAA Join and Downlink commands.
319 +For this case, We have monitored the loss of data traffic, which is the loss of 2M data traffic per day. the users can adjust the interval time following screenshots.
