– 5G Backup WWAN adds a 5G fallback layer to existing UniFi gateways, using an Ethernet-connected antenna stick with no internal power source (requires PoE).
– Supports eSIM and SIM slot; in the US, can operate without a physical SIM thanks to a T-Mobile partnership (likely using an eSIM profile).
– Uses RedCap (reduced-capability 5G) for IoT-oriented features; speeds around 10% faster than LTE backup, but prioritizes reliability over high throughput.
– Requires a cloud gateway in the network to function; price is about $99 for the antenna stick.
Overview
Ubiquiti has announced the UniFi 5G Backup WWAN backup solution. According to the manufacturer, the fallback solution can add a 5G connection as a backup layer to any current gateway. UniFi 5G Backup is a simple antenna stick solution that can be mounted to a wall, for example. A status display shows current connection information. The antenna connects via Ethernet and is automatically integrated into the UniFi network. However, since the device does not have a power connector, it requires a port with Power over Ethernet support.
Global Availability and SIM Options
At least in the US, UniFi is cooperating with T-Mobile US. The stick can therefore be used without inserting a SIM card. However, there is still a SIM card slot. According to Ubiquiti, the device has no SIM lock. The eSIM standard is also supported. Presumably, the T-Mobile SIM is stored as an eSIM profile. Whether there is a partner in Europe cannot be determined from the technical specifications provided for Europe. Ultimately, that only means sysadmins need one additional step, which is rarely required.
Technical Basis
Technically, the 5G solution uses the RedCap principle, short for reduced capabilities, which the GSMA has been promoting for some time primarily for IoT applications. This means that 5G features have been implemented, but speed is not a high priority. Accordingly, the backup solution is only around 10% faster in 5G mode than when the backup connects via LTE (220 vs. 195 Mbps). However, the stick should benefit from the reliability improvements that 5G can offer.
Pricing and Ordering
The antenna can already be ordered and costs around $99 at the brand’s official US store. The antenna can only be used if there is a (cloud) gateway in the network.
