Ubiquiti UniFi UDB is a compact, plug-and-play wireless bridging PoE adapter designed to simplify outdoor point-to-point connectivity. Featuring UniFi WiFi Auto-Link, it enables seamless client-side bridging to UniFi access points, making it ideal for extending networks across outdoor spaces without complex configurations.

Optimized for client-mode operation, the UDB connects to UniFi APs (mesh only) but does not support bridging with other UDB units or acting as a parent device. It’s part of the UniFi Directional Bridge family, which includes more advanced models like the UDB Pro and UDB Sector for point-to-point and point-to-multipoint setups.

With its sleek design and ease of deployment, the UDB is a cost-effective solution for extending wireless coverage in outdoor environments.
