1.2	498
83.1	499	Below list the place where the data traffic will use.
18.1	500
83.1	501	* Valid uplink data to LoRaWAN server or IoT server. ( We can't reduce this as they are the data we want)
	502	* Invalid uplink sensor data to LoRaWAN serevr. ( See Filter unwanted packets)
	503	* LoRaWAN Status push or polling data to LoRaWAN server . ( We can reduce this part , see below for discussion)
	504	* System Keep Alive data. ( To ensure the system is more robust, can be disabled)
87.1	505	* system Time synchronization Checking
83.1	506	* Auto update ( Software auto update, can be disabled)
18.1	507
83.1	508	=== 7.1.1 LoRaWAN Status push or polling data to LoRaWAN server ===
1.2	509
94.2	510
83.1	511	When gateway connect to LoRaWAN server via LoRaWAN protocol, besides the sensor data uplink/downlink. gateway will still need to:
1.2	512
83.1	513	* Uplink self-status to the LoRaWAN server every 30s. the users can adjust Keep Alive Period as below
	514	* 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.

1.2	517
18.1	518
83.1	519	=== 7.1.2 System Keep Alive data ===
71.3	520
94.2	521
83.1	522	System Keep Alive Data is used to check gateway-network status and fix possible issue. Gateway will check every 15 seconds and generate traffic.
1.2	523
83.1	524	Base on 15 seconds per check, the data traffic is about 2M data traffic per day. Users can adjust Keepalive Interval as below.

83.1	529	=== 7.1.3 Auto update ===
1.2	530
94.2	531
83.1	532	Gateway will check for update every day for new configure or software. User can disable them by below method.
39.2	533
1.2	534
83.1	535	=== 7.1.4 Filter unwanted packets ===
43.1	536
94.2	537
84.1	538	When gateway connect to LoRaWAN server via LoRaWAN protocol , Gateway will by default get every possible LoRaWAN packets and forward to LoRaWAN server. If there are sensors from others in the same area, such sensor data will also be forward to LoRaWAN server ( they will be ignore by the server). This also consume data.
