The Ubiquiti LTE Backup Pro (U-LTE-Backup Pro) is a robust LTE failover solution designed specifically for UniFi gateways, ensuring uninterrupted internet connectivity during primary WAN outages. Powered over PoE (requires PoE+ for passthrough functionality), this device supports your own nano-SIM card for LTE data (data-only), primarily optimized for the AT&T network in the US, with region/operator-specific variants available.

Key technical highlights include an LTE Category 4 radio with 2x2 MIMO supporting LTE bands B2, B4, B5, B12, B14, and B66, delivering up to 150 Mbps downlink and 50 Mbps uplink speeds under optimal conditions. The device is equipped with dual GbE RJ45 ports (one PoE input, one passthrough output) and an RP-SMA female connector for an optional external antenna, enhancing signal reception.

Compact and versatile, the LTE Backup Pro features a 1.54" onboard status display for quick device and LTE signal information, a 74 Kc MIPS processor running at 775 MHz, and 128 MB DDR2 memory. Installation options include flexible wall mounting or using the included foot/desk stand.

Managed seamlessly via the UniFi Network application, this device creates a GRE tunnel to your UniFi gateway for smooth failover experience. It operates within a voltage range of 44–57 V DC, consuming up to 8.5 W (excluding passthrough power).

Package includes: LTE Backup Pro unit, wall mount, foot stand.
