4G Routers
for industrial communication and IIoT
4G routers are used to enable secure and reliable connectivity in industrial systems where fixed networks are absent, impractical, or used as redundant communication.
They are a central component in remote monitoring, automation and IIoT solutions.

FAQ – Frequently Asked Questions about 4G Routers
When are 4G routers the right choice?
4G routers are the right choice when industrial systems need remote access, mobile connectivity or independent communication.
- Control cabinets and machines without access to a fixed network
- Remote monitoring of PLC, HMI and IIoT devices
- Temporary or mobile installations
- Redundant communication as backup to fixed Ethernet
4G routers are often used to ensure availability and continuity of critical systems.
When might other solutions be more appropriate?
4G routers are not always the best solution in all network applications.
- Fixed and stable internal network communication within cabinets → select Ethernet switch
- Only local communication without the need for external connectivity → internal LAN solution
- Very high bandwidth or low latency requirements → fixed industrial Ethernet
How are 4G routers used in industrial systems?
4G routers are used as a communication link between industrial systems and external networks or cloud services.
Common uses:
- Remote access to PLC and control systems
- Data transfer from sensors and IIoT platforms
- Monitoring of machines and energy systems
- Redundant communication in case of network outage
When is 4G router used in industrial installations?
When remote access or mobile connectivity is required for operation, monitoring or service.
Can a 4G router be used as a backup to a fixed network?
Yes, they are often used as redundant communication in the event of a network outage.
Are industrial 4G routers built for continuous operation?
Yes, they are adapted for demanding environments and long-term use.
Do 4G routers need external antenna?
It depends on the installation environment and signal strength.
