LTE backup ensures your business remains online even if your primary internet link goes down. Your router automatically switches to mobile data without interruption.
How Failover Works
-
The router detects loss of NBN/Fibre connectivity
-
The 4G/5G SIM activates
-
Internet traffic is routed through mobile until the primary link returns
This process typically takes 5–30 seconds, depending on your hardware.
What You’ll Notice During Failover
-
Slight speed reduction (mobile networks are shared)
-
VoIP services may experience minor jitter
-
Cloud apps may reconnect quickly
-
VPN tunnels may temporarily drop
Failback (Returning to Primary Link)
Once the main connection restores, the router automatically switches back to the higher-speed service.
This is seamless and usually unnoticed by your team.
