++(% class="wikigeneratedid" %)
++=== 7.1.1 LoRaWAN Status push or polling data to LoRaWAN server ===
++When gateway connect to LoRaWAN server via LoRaWAN protocol, besides the sensor data uplink/downlink. gateway will still need to:
--//1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.//
++* Uplink self-status to the LoRaWAN server every 30s. the users can adjust **Keep Alive Period** as below
++* 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.
--//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.//

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