Ubiquiti UniFi 5G Backup is a router designed for use within the UniFi ecosystem. It supports UniFi 5G RedCap connectivity, a simplified version of 5G that delivers lower throughput while maintaining high connection reliability and low latency. In Europe, it operates exclusively on 5G SA networks and requires a compatible mobile subscription. If your carrier plan does not support 5G RedCap, the U5G will automatically fall back to LTE. The maximum theoretical mobile data throughput is 220 Mb/s for downloads and 120 Mb/s for uploads. The device is equipped with a single 1G Ethernet port, which also serves as the PoE (802.3af) power input. The primary purpose of the U5G is to serve as a backup Internet connection in UniFi networks, ensuring uninterrupted connectivity in the event of a failure of the primary WAN link.
Router with 5G RedCap Connectivity, UniFi
The offered product is a router designed for use within the UniFi ecosystem. It supports 5G RedCap connectivity, a simplified version of 5G SA that provides lower throughput while retaining the key advantages of 5G, including high network availability and low latency. A compatible mobile subscription is required to use 5G RedCap. If you are using a standard mobile plan, the U5G will connect via LTE instead. The maximum theoretical 5G RedCap throughput is 220 Mb/s for downloads and 120 Mb/s for uploads. The device is designed to serve as a backup Internet connection for networks based on the UniFi platform.


Nano SIM Slot and eSIM Support
The device features a physical Nano SIM slot and also supports eSIM functionality. This allows you to use services from multiple mobile network operators, increasing connection reliability and ensuring greater network resilience.
Connect to the Gateway's WAN or LAN Port
The UniFi 5G Backup can be connected to either a WAN or LAN port anywhere within your network. This allows you to install the U5G in the location with the best possible mobile signal, while also simplifying deployment and eliminating the need to modify the existing network infrastructure.


PoE Power Supply, Compact Enclosure
The U5G is equipped with a single 1G Ethernet port, which also serves as the PoE power input. No alternative power input is available. The device features a compact enclosure that blends seamlessly into most indoor environments. Using the included mounting accessories, the U5G can be installed on a wall, placed on a stand, or mounted to a window, depending on your deployment requirements. For optimal performance, the router should be installed in a location with strong 5G or 4G signal coverage.
