166 += 5. How does the gateway connect to the network via a USB 4G Dongle =
167 +
168 +== 5.1 Introduction ==
169 +
170 +Prerequisite: Requires a USB 4G Dongle and a supported gateway firmware
171 +
172 +This introduces a setup and configured gateway for using a USB 3g/UMTS-modem for WAN connection.
173 +
174 +Many mode (and most **LTE**) usb modems provide **qmi**, **mbim**, **ncm**, **rndis** protocol for connection instead of legacy **ppp** protocol, they are faster and better, overall recommended. For more information: [[https:~~/~~/openwrt.org/docs/guide-user/network/wan/wwan/3gdongle>>url:https://openwrt.org/docs/guide-user/network/wan/wwan/3gdongle]]
175 +
176 +This is not beginner-friendly due to too many protocols.
177 +
178 +
179 +== 5.2 How to use the USB-Dongle at the gateway ==
180 +
181 +Most of the products can be used on the gateway, but because their protocols are different, they are not used in the same way.
182 +
183 +For example, the Huawei-E3372/E8372 is using Hilink mode or NCM mode.
184 +
185 +{{{ Huawei-E3372/E8372
186 + Check E3372 version to determine the mode.
187 + The version numbers starting with 21 is NCM mode
188 + The version numbers starting with 22 is Hilink mode
189 + The E8372 only have Hilink mode
190 + Note：The e3372 in the vast majority of cases is Hilink mode
191 +}}}
192 +
193 +== 5.3 Hilink mode ==
194 +
195 +Gateway upgrade to the specified firmware:
196 +
197 +[[Hilink.mode~~-~~-build-v5.4.1625627505>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_Gateway/LG308-LG301/Firmware/USB-Dongle_firmware/Hilink.mode--build-v5.4.1625627505-20210707-1113/]]

201 +USB-Dongle plugs into the gateway USB port
202 +
203 +Check the USB module via comman lsusb

205 +Note : User neet to do that connect gateway command line via ssh.

258 += 6. How to reduce data traffic =
259 +
260 +== 6.1 Introduce ==
261 +
262 +The gateways will use the data traffic were below two places.
263 +
264 +~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink.
265 +
266 +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.
267 +
268 +[[image:https://wiki.dragino.com/images/thumb/b/bc/LoRa_interval_time_setting.png/600px-LoRa_interval_time_setting.png||height="282" width="600"]]
269 +
270 +LoRa interval time setting
271 +
272 +2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s.
273 +
274 +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.
