    We have some old Kerlink Wirnet Station LoRaWAN Gateways () that are connected to our servers with their internal 2G/3G modems for mobile Internet connection. 3G is being phased out in Europe, 2G is not. But 2G (more precisely GPRS) is sometimes not fast enough and its bandwidth is even lower in crowded cities. Therefore, we need to change the backhaul connection of our gateways to 4G mobile Internet. There are two approaches to this: 1) using an external 4G modem that has an Ethernet connection (), 2) connect a 4G USB stick to the USB connector of the Kerlink Wirnet Station, like the Huawei K5150 (), or the
