302 The gateways will use the data traffic were below two places.
303
304 ~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.
305
306 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.

311
312 2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s.

314 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.
