Network bridge Ubiquiti Building-to-Building Bridge 5.15-5.875 GHz IEEE 802.3af

60 GHz point-to-point (PtP) bridge with 802.11ad and a 5 GHz radio for redundancy, delivering high-throughput connectivity up to 500 m. The UniFi Building-to-Building Bridge is supplied as a pair of radios and integrates with UniFi Controller for centralized management. It supports bi-directional throughput of more than 1.7 Gbps and provides plug-and-play setup for fast deployment of gigabit links between buildings.

Advantages

The device combines a 60 GHz high-capacity link with a 5 GHz backup radio for resilient connectivity. Managed via UniFi Controller, it enables centralized configuration, monitoring, and diagnostics. Supplied as a complete pack of two radios, it reduces installation complexity and offers PoE power support and Gigabit Ethernet interfaces for straightforward integration into existing networks.

Suitable for

• Short-range building-to-building connectivity (up to 500 m)
• High-bandwidth links for video, data replication, and backhaul
• Sites requiring a redundant radio path using 5 GHz
• Environments where quick plug-and-play deployment is needed

Key specifications

• Frequency bands: 60 GHz (primary) and 5.15–5.875 GHz (backup)
• Wireless standard: 802.11ad (60 GHz) and compatible 5 GHz operation
• Throughput: >1.7 Gbps bi-directional
• Range: up to 500 m
• Antenna gain (max): 17.2 dBi
• Transmit power: 36.5 dBm (signal strength as provided)
• Ethernet: Gigabit Ethernet (10/100/1000 Mbps)
• Power: PoE support, maximum consumption 11 W
• Material and colour: polycarbonate, white
• Weight: 0.376 kg (per unit)
• Standards: IEEE 802.3af

How to use

Mount the two radios facing each other with a clear line of sight and connect each unit to the local network using the Gigabit Ethernet port. Provide power via a compatible PoE injector or switch that meets IEEE 802.3af. Use the UniFi Controller to adopt the devices, configure the 60 GHz primary link and the 5 GHz redundancy settings, and monitor link status and performance. Allow a few minutes for initial link establishment and automatic optimisation.

Recommendations

Install with unobstructed line of sight and minimal nearby 60 GHz/5 GHz interference. For maximum reliability, align antennas precisely and verify PoE supply capacity. Use the 5 GHz radio as backup in scenarios with occasional 60 GHz attenuation due to weather or obstructions.
