Ubiquiti U-LTE-BACKUP PRO U-LTE-Backup Pro

Ubiquiti U-LTE-BACKUP PRO LTE Backup Gateway

Overview

The Ubiquiti U-LTE-BACKUP PRO (MPN: U-LTE-BACKUP PRO) is a compact LTE backup gateway designed to provide secondary connectivity in UniFi network deployments. Operating as a failover device, it bridges LTE cellular networks with wired Ethernet infrastructure, ensuring continuity when primary WAN connections fail. The unit's lightweight form factor—just 1.6 pounds—enables flexible mounting in network closets, equipment racks, or remote edge locations without requiring significant space or structural reinforcement.

Key Features

The U-LTE-BACKUP PRO accepts PoE+ input across its primary Gigabit Ethernet port, eliminating the need for dedicated power supplies in most deployments. A secondary Gigabit Ethernet port with PoE output enables daisy-chaining or powering downstream UniFi equipment, supporting integrated network topologies. Both ports operate at 1 Gbps throughput, providing adequate bandwidth for backup and supplemental connectivity scenarios. The gateway integrates natively with UniFi network management platforms, allowing administrators to configure failover policies, monitor cellular link health, and manage traffic priorities from a unified dashboard.

Deployment Scenarios

The U-LTE-BACKUP PRO excels in branch office redundancy, where primary fiber or broadband connections may experience outages. Deploy it alongside existing UniFi gateways to automatically assume traffic routing when primary links fail. Remote site surveillance and IoT deployments benefit from its cellular backhaul capability, reducing dependency on unreliable fixed-line connectivity. Multi-site organizations use the device to ensure persistent management access and emergency communication across distributed locations.

Network Integration

Integration with UniFi Dream Machines, Dream Machine SE, or other UniFi gateways follows standard failover patterns. The PoE+ input draws power from existing PoE+ switches or injectors, while the PoE output port can supply power to downstream access points or cameras. Configuration occurs through the UniFi Controller, where administrators define WAN priority, failover thresholds, and load-balancing rules. LTE connectivity requires a compatible cellular module and active carrier plan; consult Ubiquiti documentation for regional module compatibility and carrier support.

Installation Notes

Mount the U-LTE-BACKUP PRO in proximity to the primary gateway and cellular antenna for optimal signal reception. Ensure the PoE+ source supports sufficient power budget (minimum 90W for PoE+). Connect the primary WAN link to the PoE+ input port and the secondary gateway or PoE device to the output port. A manufactured origin of CN ensures supply chain consistency and compatibility with global UniFi ecosystems. Testing failover behavior before production deployment prevents unexpected outages and validates carrier activation and signal strength in your specific location.
