Description
Ubiquiti UDB-US WiFi 5 Bridge
The Ubiquiti UDB-US is a compact WiFi 5 (802.11ac) bridge device designed for point-to-point or client bridging applications in the 5 GHz band. Delivering up to 866.7 Mbps with 2x2 MIMO (BW80), it provides reliable high-throughput wireless connectivity for environments where running Ethernet is impractical. Its wall or table mounting options and AC power input (100–240V) make it easy to deploy in a variety of indoor locations without requiring PoE infrastructure.
The UDB-US features both an internal 5 dBi antenna and an RP-SMA connector for attaching an optional external omni-directional antenna (4 dBi, 360° x 30° coverage), giving installers the flexibility to optimize signal direction and coverage based on the specific deployment environment. A single GbE RJ45 port provides wired connectivity to the bridged device. WPA2 AES wireless security ensures encrypted link protection, and the device supports U-NII-1 through U-NII-3 frequency bands for regulatory compliance across US and Canadian markets.
Managed over WiFi with a polycarbonate enclosure built for long-term durability, the UDB-US operates from -10°C to 40°C (14°F to 104°F) and is NDAA compliant, FCC, IC, and CE certified. Max power consumption is 25W from AC input, or 10W excluding PoE output.
Key Features:
- WiFi 5 (802.11ac) at up to 866.7 Mbps on 5 GHz with 2x2 MIMO; delivers reliable high-throughput bridging where Ethernet cabling is not feasible.
- Dual antenna system — internal 5 dBi and RP-SMA for external omni (4 dBi, 360°); provides installation flexibility to optimize coverage and signal direction.
- AC powered (100–240V); eliminates the need for PoE infrastructure, simplifying deployment in standard outlet locations.
- Single GbE RJ45 port; connects a wired device directly to the wireless bridge for full-speed wired/wireless integration.
- Supports U-NII-1 through U-NII-3 (5150–5850 MHz); ensures full US and Canadian regulatory compliance across all licensed 5 GHz bands.
- WPA2 AES wireless security; protects the wireless bridge link against unauthorized access and eavesdropping.
- NDAA Compliant; qualifies for government and federally funded network bridge deployments.
