Robustel R5020 Industrial 5G Router

Robustel have announced the launch of their new 5G Router.  The Robustel R5020 5G router is their new high speed, industrial grade M2M router with embedded 5G modem to provide high speed 5G connectivity with a secure and robust, industrial grade router platform to deliver secure, high speed 5G Internet ideal for providing an office or business grade 5G router solution, or even a homeworker 5G router solution in this age of homeworking and demand for high speed Internet.

The Robustel R5020 5G router is also ideal for M2M applications where remote monitoring and management of equipment needs a high speed 5G Internet connection.  But with a competitive price for a 5G router it may just be that you want to use the R5020 router for a 4G connection to save the hassle of upgrading a 4G router to a 5G router in the future and the competitive pricing from Robustel certainly makes this possible.

About the Robustel R5020 5G Router

With its on-board smarts, compact size and a competitive price point the R5020 is the perfect solution for customers looking to make the jump to 5G. Offering a similar form factor and feature set to Robustel’s popular R2110 series router the R5020 is also an ideal transitional product for existing Robustel customers to move from LTE to 5G.

The R5020 is powered by Robustel’s proprietary operating system RobustOS, a Linux-based OS with a clean, simple and modular user experience developed by Robustel specifically for use in Robustel devices. With additional CPU capabilities compared to traditional LTE routers the R5020 also offers the ability for customers to perform more in-depth EDGE computing tasks through writing applications using the RobustOS Software Development Kit (SDK).

Suitable Applications

With its on-board smarts, compact size and a competitive price point, the R5020 is the perfect solution for In-vehicle Applications, Fixed-Line Replacement and Failover with minimal configuration or engineering requirements. With its industrial interfaces the R5020 also opens doors for IoT applications in manufacturing, agriculture, security and smart cities that need high speed internet access.

Robustel R5020 5G Router and 5G Fixed IP SIM Cards


The R5020 router is compatible with all 5G SIM Cards so you can use this router with a standard 5G Data SIM card when using it for 5G Internet, for example as an office 5G router or a 5G Backup router to provide 5G Internet in the event that a wired Internet service fails or maybe even use the R5020 router as a 5G homeworker router to provide high speed 5G Internet for homeworkers. In all these instances it is likely that you do not need remote access to your 5G router so a normal 5G SIM Card will provide an adequate 5G connectivity solution. However, if you need remote access to your 5G router then you will need to use a 5G SIM Card with a Fixed IP address which are called Fixed IP SIM Cards and in particular for a 5G SIM it would be called a 5G Fixed IP SIM Card. This is a service that provides a 5G SIM Card that connects to the 5G mobile network, but when the router is configured you enter the APN in the mobile network settings for your Fixed IP SIM provider and the router connects over the 5G network to their APN and at this point the Fixed IP SIM network provider can provide the connection with either a Public or Private IP address. In the case of a 5G Public Fixed IP SIM Card this means the router can be connected to from any device on the Internet, so your Robustel R5020 router is open to anyone on the Internet so you would need to ensure that you correctly configure the router firewall and security settings and if using port forwarding with the R5020 router then you would need to ensure that any devices on the LAN open to the internet are also correctly configured to ensure their integrity. A 5G Private Fixed IP SIM Card would give the router a Private Fixed IP address so it would not be open to the public Internet so in order to connect to your Robustel R5020 router you would need to connect your PC to your Fixed IP SIM Card providers network first of all using a VPN connection and then you would be able to access your router and connected devices.

The Robustel R5020 5G SIM Router is ideal for applications including 5G CCTV connectivity or other remote access and monitoring applications that require a high speed 5G Internet connection.
