260 +== 6.1 Introduce ==
484 484  
485 -== 7.1 How the gateway will consume data traffic ==
262 +The gateways will use the data traffic were below two places.
486 486  
487 -Below list the place where the data traffic will use.
264 +~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.
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 -* system Time synchronization Checking
494 -* Auto update ( Software auto update, can be disabled)
266 +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.
495 495  
496 -=== 7.1.1 LoRaWAN Status push or polling data to LoRaWAN server ===

497 497  
498 -When gateway connect to LoRaWAN server via LoRaWAN protocol, besides the sensor data uplink/downlink. gateway will still need to:
270 +LoRa interval time setting
499 499  
500 -* Uplink self-status to the LoRaWAN server every 30s. the users can adjust **Keep Alive Period** as below
501 -* 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.
272 +2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s.
502 502  
503 -[[image:image-20220527155108-13.png]]
274 +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.

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

509 509  
510 -Base on 15 seconds per check, the data traffic is about 2M data traffic per day. Users can adjust **Keepalive Interval** as below.

515 -=== 7.1.3 Auto update ===
516 -
517 -Gateway will check for update every day for new configure or software. User can disable them by below method.
518 -
519 -
520 -=== 7.1.4 Filter unwanted packets ===
521 -
522 -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.
