	307
	308	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.

	313
	314	2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s.
	315
	316	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.
