Huawei 4G Dongle
Many companies that needed remote access to their devices over 3G or 4G mobile broadband would commonly use a 3G or 4G dongle connected to their PC or device but this often resulted in outages where the mobile network had disconnected the dongle from the network becuase 3G, 4G and 5G mobile Internet connectivity is an always available service and not an always on service. This meant that users of dongles had to visit site to unplug the dongle and plug it back in again so it would reconnect as a new 4G connection on the mobile network.
Now you can prevent these expensive and inconvenient site visits by swapping your 3G or 4G Dongle for a 4G router like the Teltonika RUT950 that has a built-in 4G modem and SIM card slot so you can insert your 4G SIM card and provide connection to your device via Ethernet or WiFi. The difference when using an industrial grade 4G router is that it has programmable features like ping reboot / Cell ICMP Check so that the router checks the status of the mobile connection and when the router is disconnected from the 4G Internet by the mobile network, the router can automatically reboot and reconnect to the mobile network.
By using a 4G router instead of a 4G dongle you can provide a more reliable 4G Internet connection for your M2M remote access and monitoring application.
Also, if you need rural 4G Internet and are using a 4G Dongle you might find you have poor signal reception and the antenna connector for an outdoor 4G antenna is a little flimsy, so by using a 4G router with your 4G SIM Card you can install a much better quality outdoor 4G antenna solution.
