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.

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
