UB-UDB-SWITCH

Overview

Ubiquiti UDB-Switch UniFi Device Bridge Switch (35W) is a compact PoE+ networking solution designed for high-speed deployments where wired performance meets next-generation wireless bridging. Built to integrate smoothly with UniFi WiFi, it enables a reliable wireless uplink using WiFi 7 while delivering multi-gigabit switching for demanding devices. With support for 6 GHz operation and multiple spatial streams, it is well suited for modern offices, edge installations, and flexible network expansions where running fiber or copper is impractical.

Description

The UDB-Switch (35W) combines multi-gigabit Ethernet switching with WiFi 7 device bridging in a compact form factor. It delivers fast wired connectivity through a mix of 10 GbE and 2.5 GbE ports while supplying PoE+ power to connected devices. Designed for seamless UniFi integration, it provides a high-capacity wireless uplink, simple deployment, and clear at-a-glance status monitoring through a built-in display.

Features

High-speed wireless bridging with WiFi 7
Designed to operate with UniFi WiFi, the switch supports WiFi 7 bridging across the 6 GHz and 5 GHz bands.

• Up to 5.8 Gbps wireless throughput on 6 GHz
• Up to 4.3 Gbps wireless throughput on 5 GHz
• Four spatial streams for stable, high-capacity links

Multi-gigabit Ethernet connectivity
The port layout supports both aggregation and high-performance endpoints.
