Three-link intelligent backup ensures network online

In modern industrial IoT and automation scenarios, the stability of network connectivity directly impacts business continuity and data security. The WIS901 4G industrial router is purpose-built for high-reliability networking requirements, supporting 4G, Ethernet, and WiFi multi-link backup with intelligent automatic failover, ensuring comprehensive network reliability and a truly “always online” experience.

Three-link intelligent backup

▶ Multi-Link Backup and Flexible Access

The WIS901 4G router supports three mainstream network access methods:

  • Ethernet (wired): Provides high-speed, stable primary connectivity for fixed locations.
  • 4G Mobile Network: Features a global 4G module compatible with SIM cards from multiple operators, suitable for mobile or wired-unavailable environments.
  • WiFi Wireless Network: Offers flexible wireless access, ideal for temporary or mobile deployments.

Users can flexibly configure network access priorities in the management interface according to actual needs. For example, a common setup is Ethernet as primary, 4G as secondary, and WiFi as the third option.

▶ Intelligent Switching and Automatic Failover

WIS901 features intelligent network switching. When the primary network fails (such as a wired disconnection or 4G signal loss), the device automatically switches to the next available network. This process is seamless to users and does not interrupt ongoing business data transmission. The switching mechanism supports various modes:

  • Primary/Backup Priority (e.g., Ethernet first): The primary network is used by default; in case of failure, it automatically switches to 4G or WiFi.
  • Hot Backup: Multiple network modules are online simultaneously, enabling rapid switching to minimize business interruption.
  • Cold Backup: Only the primary network is online; backup links are activated after a failure to save resources.

▶ Real-Time Monitoring and Fault Alerts

WIS901 supports visualized backend management, real-time monitoring of each link’s status, traffic consumption, and switch records. When network anomalies occur, the system can automatically push alert notifications and log detailed switching reasons, helping maintenance personnel quickly troubleshoot and restore service.

▶ Industrial-Grade Security and Stability

Beyond multi-link backup and automatic switching, WIS901 integrates multiple industrial-grade security measures, including firewall, VPN encryption, access control, DMZ, and intrusion detection and prevention systems (IDPS), ensuring data transmission is safe and reliable. The device features an all-industrial design, supports 24/7 stable operation, adapts to harsh environments, and includes a hardware watchdog for self-detection and self-recovery.

▶ Conclusion

With 4G, Ethernet, and WiFi multi-link backup and intelligent automatic failover, the WIS901 4G industrial router provides industrial users with a highly reliable and secure network connectivity solution. No matter when the primary network fails, the device can automatically switch to an available link, ensuring business data is “always online” and supporting enterprises in their digital transformation and intelligent upgrades.
