The Ubiquiti UniFi 5G Backup Modem (U5G) is designed to ensure your network stays online even when the primary connection fails. This compact, PoE-powered device integrates seamlessly into existing UniFi deployments to provide automatic internet backup without requiring a standalone configuration. With support for both Nano SIM and eSIM, along with versatile mounting options including desktop, wall, or window setups, it offers flexibility for various environments. The unit features a 1.14-inch status display for quick connectivity checks and includes bundled data pack savings on eligible plans.
The Ubiquiti UniFi 5G Backup Modem delivers reliable redundancy for your network infrastructure by leveraging the latest RedCap technology. It connects directly to any UniFi PoE port, eliminating the need for separate power adapters or complex setups. The device supports a wide range of frequency bands for both 5G and LTE networks, ensuring broad carrier compatibility and optimal signal strength in most locations.
Key Connectivity Benefits
The system operates within a robust temperature range of 0 to 40 degrees Celsius and maintains reliability in humid conditions up to 95% non-condensing. It meets NDAA compliance standards and carries certifications from major regulatory bodies including FCC, IC, PTCRB, GCF, AT&T, and T-Mobile, ensuring it adheres to strict industry safety and performance requirements.
Physical dimensions for the device are 200 x 38 x 20.2 mm, while the included table stand measures 48.1 x 48 x 55.2 mm. The enclosure is constructed from durable polycarbonate and aluminum alloy materials to withstand daily wear. It weighs approximately 122 grams on its own, with the wall mount adding another 66 grams to the total setup weight.
The hardware relies on two embedded omni-directional cellular antennas to ensure consistent signal reception regardless of orientation. Management is handled entirely through Ethernet using the UniFi Network application version 10.4.57 or later, with mobile app support available for iOS version 10.35.0 and Android version 10.38.2. A single factory reset button allows for easy troubleshooting if needed.
