293 == 6.1 Introduce ==
294
295 The gateways will use the data traffic were below two places.
296
297 ~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.
298
299 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.

303 LoRa interval time setting
304
305 2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s.
306
307 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.
