Article 4 of 8 | Connectivity & Reliability Series

In a smart factory, a single minute of internet downtime can halt production lines, delay shipments, and cost thousands of dollars. While fiber or ADSL connections are generally reliable, they are not invincible. Implementing a 5G/LTE Failover strategy is essential for maintaining 24/7 operational continuity.

The Cost of Downtime: Statistics show that mid-to-large scale industrial facilities lose an average of $5,000 per hour during unplanned network outages.

What is Industrial Failover?

Failover is the process of automatically switching to a secondary internet source (like a cellular 4G/5G network) when the primary connection fails. HUBBOX Gateways handle this transition in milliseconds, ensuring that your Secure Remote Access and data flow remain uninterrupted.

Reliability Dual-Path Connectivity

Combine wired WAN with 5G/LTE modules to create a redundant network architecture that never sleeps.

Performance High-Speed 5G

Leverage the ultra-low latency of 5G for real-time remote monitoring and high-bandwidth data transmission.

Comparison: Standard Router vs. HUBBOX Failover

Standard Router
  • Manual switch required
  • Significant packet loss
  • No specialized OT security
  • Complex cellular config
HUBBOX IIoT Gateway
  • Automated Instant Switch
  • Seamless Data Recovery
  • Encrypted Cellular Tunnel
  • Plug & Play Global SIM Support

Why Your Facility Needs Cellular Backup

  • Critical Alarm Protection: Ensure emergency alerts reach the cloud even if the main line is cut.
  • Remote Fixes Anywhere: Access machines in remote areas where wired internet is unavailable.
  • Auto-Recovery: Automatically switches back to primary WAN once the connection is restored.
