UniFi — NDAA Compliant
UniFi Building-to-Building Bridge Pro — 5 GHz Gigabit Wireless Bridge (UDB-Pro)
The Ubiquiti UniFi Building-to-Building Bridge Pro (UDB-Pro) creates a fast, reliable gigabit wireless link between two locations up to 5 km apart — no trenching, no fibre, no cabling between sites. With a 19 dBi internal antenna, 2×2 MIMO WiFi 5, four signal-strength LEDs for easy aiming, and a built-in PoE passthrough output to power a downstream camera or access point, it's the simplest way to extend your network across a car park, warehouse, or campus. IPX6 weatherproof and rated from −40 to 60°C, it's built for Australian conditions. Genuine Ubiquiti stock with fast Australia-wide shipping.
Why Choose the Building Bridge Pro?
Gigabit Link up to 5 km
Connect two buildings with a high-throughput 5 GHz WiFi 5 link reaching up to 5 km line-of-sight — perfect where running fibre or copper isn't practical.
Easy Aiming, Fast Setup
Four signal-strength LEDs and UniFi management make alignment and configuration quick — point, peak the signal, and you're online.
19 dBi 2×2 MIMO
A high-gain 19 dBi internal antenna with 2×2 MIMO delivers up to 867 Mbps (80 MHz) of stable wireless backhaul.
PoE Passthrough Output
A second GbE port with passive PoE output lets you power a downstream UniFi camera or access point at the remote building — no extra power run required (PoE+ input required for PoE output).
Built for the Outdoors
IPX6 weatherproof UV-resistant polycarbonate housing rated −40 to 60°C and 200 km/h wind loading — engineered for harsh Australian sites.
NDAA Compliant
Fully NDAA Section 889 compliant for government, defence, and security-sensitive deployments.

Best For
Building-to-Building
Link a main office to a shed, warehouse, or second building without trenching fibre.
Car Parks & Yards
Extend the network to remote CCTV cameras or access points across open ground.
Rural & Farm Sites
Bridge internet to outbuildings up to 5 km away over line-of-sight.
Temporary & Events
Fast-deploy a high-bandwidth link where cabling is impractical.
- A point-to-point link requires two UDB-Pro units (one at each building) with clear line-of-sight.
- Powered by the included 48 V PoE adapter; PoE+ input is required to use the PoE passthrough output.
- The second GbE port provides passive PoE out to power a downstream camera or access point.
- Use the four signal-strength LEDs to peak alignment for best throughput.
Frequently Asked Questions
How far can the UDB-Pro reach?
Up to 5 km with clear line-of-sight between the two units. Obstructions, trees, and weather can reduce effective range.
How many units do I need?
A wireless bridge link needs two units — one mounted at each building, aimed at each other.
Can it power a camera at the far end?
Yes. The second GbE port provides passive PoE output to power a downstream UniFi camera or access point (a PoE+ input is required to enable PoE output).
Is it weatherproof?
Yes — IPX6 rated with a UV-resistant housing and a −40 to 60°C operating range, suited to Australian outdoor conditions.
What throughput can I expect?
Up to 867 Mbps at the radio (80 MHz, 5 GHz). Real-world throughput depends on distance, line-of-sight, and interference.
Is the UDB-Pro NDAA compliant?
Yes. Ubiquiti is a US-based manufacturer and the UDB-Pro is NDAA Section 889 compliant.
