Ubiquiti UDB Wireless Device Bridge

The Ubiquiti UDB delivers plug-and-play wireless bridging with integrated UniFi WiFi Auto-Link technology. This compact PoE adapter connects wired devices to your wireless network without complex configuration, making it ideal for extending network connectivity to areas where running ethernet cables is impractical.

WiFi 5 Performance with 2x2 MIMO

Equipped with WiFi 5 (802.11ac) technology and 2x2 MIMO spatial streams, the UDB achieves maximum data rates up to 866.7 Mbps on 80MHz channel bandwidth. The dual-antenna system combines an internal 5 dBi antenna with an external RP-SMA connector for an optional 4 dBi omni-antenna, providing flexible deployment options and reliable wireless performance.

Seamless PoE Integration

The UDB functions as both a wireless bridge and PoE adapter, accepting 100-240V AC input and delivering power to connected devices through its single GbE RJ45 port. With 25W total power consumption and 10W available for PoE output, it supports network devices like IP cameras, access points, and VoIP phones without requiring separate power supplies.

Simple Deployment and Management

Wall or table mounting options and compact dimensions (130 x 55 x 34 mm) allow installation in tight spaces. The polycarbonate enclosure houses four blue signal LEDs and one white/blue indicator LED for quick status monitoring. WiFi management through UniFi Auto-Link automatically establishes secure WPA2 AES encrypted connections, eliminating manual configuration steps.
