483 = 7. How to reduce data traffic =
484
485 == 7.1 How the gateway will consume data traffic ==
486
487 Below list the place where the data traffic will use.
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)
495
496 === 7.1.1 LoRaWAN Status push or polling data to LoRaWAN server ===
497
498 When gateway connect to LoRaWAN server via LoRaWAN protocol, besides the sensor data uplink/downlink. gateway will still need to:
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.
502

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.
