| 170 | = 5. How does the gateway connect to the network via a USB 4G Dongle = | ||
| 171 | |||
| 172 | == 5.1 Introduction == | ||
| 173 | |||
| 174 | (% style="color:red" %)**Prerequisite: Requires a USB 4G Dongle and a supported gateway firmware** | ||
| 175 | |||
| 176 | This introduces a setup and configured gateway for using a USB 3g/UMTS-modem for WAN connection. | ||
| 177 | |||
| 178 | 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]] | ||
| 179 | |||
| 180 | This is not beginner-friendly due to too many protocols. | ||
| 181 | |||
| 182 | |||
| 183 | == 5.2 How to use the USB-Dongle at the gateway == | ||
| 184 | |||
| 185 | Most of the products can be used on the gateway, but because their protocols are different, they are not used in the same way. | ||
| 186 | |||
| 187 | For example, the Huawei-E3372/E8372 is using Hilink mode or NCM mode. | ||
| 188 | |||
| 189 | (% class="box" %) | ||
| 190 | ((( | ||
| 191 | Huawei-E3372/E8372 | ||
| 192 | Check (% style="color:#037691" %)**E3372**(% style="color:black" %) version to determine the mode. | ||
| 193 | The version numbers starting with 21 is NCM mode | ||
| 194 | The version numbers starting with 22 is Hilink mode | ||
| 195 | The E8372 only have Hilink mode | ||
| 196 | (% style="color:#037691" %)Note：The e3372 in the vast majority of cases is Hilink mode | ||
| 197 | ))) | ||
| 198 | |||
| 199 | == 5.3 Hilink mode == | ||
| 200 | |||
| 201 | Gateway upgrade to the specified firmware: | ||

| 208 | |||
| 209 | Check the USB module via comman lsusb | ||
| 210 | |||
| 211 | Note : User neet to do that connect gateway command line via ssh. | ||

| 264 | = 6. How to reduce data traffic = | ||
| 265 | |||
| 266 | == 6.1 Introduce == | ||
| 267 | |||
| 268 | The gateways will use the data traffic were below two places. | ||
| 269 | |||
| 270 | ~1. There is the data traffic from LoRa package Forward which were the gateway status package and sensor end node uplink/downlink. | ||
| 271 | |||
| 272 | 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. | ||
| 273 | |||
| 274 | [[image:https://wiki.dragino.com/images/thumb/b/bc/LoRa_interval_time_setting.png/600px-LoRa_interval_time_setting.png||height="282" width="600"]] | ||
| 275 | |||
| 276 | LoRa interval time setting | ||
| 277 | |||
| 278 | 2. There is the data traffic from the gateway check self-network status. by default, the gateway will check network per 15s. | ||
| 279 | |||
| 280 | 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. | ||
