489 +* Valid uplink data to LoRaWAN server or IoT server. ( We can't reduce this as they are the data we want)

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)

352 352  
353 -**//The gateways will use the data traffic below two places.//**
497 +When gateway connect to LoRaWAN server via LoRaWAN protocol, besides the sensor data uplink/downlink. gateway will still need to:
354 354  
499 +* Uplink self-status to the LoRaWAN server every 30s. the users can adjust **Keep Alive Period** as below
500 +* 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.

519 +=== 7.1.4 Filter unwanted packets ===
520 +
521 +When gateway connect to LoRaWAN server via LoRaWAN protocol , Gateway will by default get every possible LoRaWAN packets and forward to LoRaWAN server. If there are sensors from others in the same area, such sensor data will also be forward to LoRaWAN server ( they will be ignore by the server). This also consume data.
