307 The gateways will use the data traffic were below two places.
308
309 ~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.
310
311 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.

315 LoRa interval time setting
316
317 2. There is the data traffic from the gateway check self-network status. by default, the gateway will check the network per 15s.
318
319 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.
