270 +The gateways will use the data traffic were below two places.
498 498  
499 -Below list the place where the data traffic will use.
272 +~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.
500 500  
501 -* Valid uplink data to LoRaWAN server or IoT server. ( We can't reduce this as they are the data we want)
502 -* Invalid uplink sensor data to LoRaWAN serevr. ( See Filter unwanted packets)
503 -* LoRaWAN Status push or polling data to LoRaWAN server . ( We can reduce this part , see below for discussion)
504 -* System Keep Alive data. ( To ensure the system is more robust, can be disabled)
505 -* system Time synchronization Checking
506 -* Auto update ( Software auto update, can be disabled)
274 +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.
507 507  
508 -=== 7.1.1 LoRaWAN Status push or polling data to LoRaWAN server ===

511 -When gateway connect to LoRaWAN server via LoRaWAN protocol, besides the sensor data uplink/downlink. gateway will still need to:
280 +2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s.
512 512  
513 -* Uplink self-status to the LoRaWAN server every 30s. the users can adjust **Keep Alive Period** as below
514 -* 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.
282 +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.

522 -System Keep Alive Data is used to check gateway-network status and fix possible issue. Gateway will check every 15 seconds and generate traffic.

524 -Base on 15 seconds per check, the data traffic is about 2M data traffic per day. Users can adjust **Keepalive Interval** as below.

537 -
538 -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.
