Ubiquiti’s new UDB Switch brings Wi‑Fi 7 uplink to places where running Ethernet simply isn’t practical, making it a smart bridge for wired IoT devices like cameras, sensors, access controls, and signage. Instead of pulling cable, you can join the switch to your main network over the air and still deliver both data and power to edge devices via PoE+.
The wireless side is built for high-density environments. The UDB Switch supports tri-band Wi‑Fi 7 (802.11be) across 6 GHz, 5 GHz, and 2.4 GHz, with WPA3 security. The 6 GHz band is especially useful in congested areas where legacy traffic can bog down 2.4 and 5 GHz. Note that 802.11b/g isn’t supported, which aligns with the device’s modern, high-performance focus.
On the wired side, you get eight RJ45 ports with PoE+ (802.3at) up to 30 watts per port, plus a mix of multi-gig speeds to match diverse deployments. One port is 10GbE and can double as a wired uplink when you do have cabling available, while the remaining ports support up to 2.5GbE via 802.3bz. This makes the switch suitable for bandwidth-hungry endpoints like high-resolution IP cameras or Wi‑Fi access points.
Power budgeting is the key detail to understand. The switch itself draws 25 watts and is capable of supplying up to 185 watts to connected devices. However, it ships with a 60-watt power adapter, which limits the available PoE budget to roughly 35 watts. If you plan to run multiple high-draw devices, you’ll want the optional 210-watt power supply to unlock the full PoE capacity.
In practical use, the UDB Switch is built for tough spots. It includes a small, non-touch status display for quick on-site diagnostics and is rated for operation from -30°C to +40°C, making it a fit for cooler environments such as warehouses, garages, or utility rooms. Keep in mind the optional 210W power supply is rated for temperatures above freezing.
Key highlights
– Tri-band Wi‑Fi 7 uplink (6 GHz/5 GHz/2.4 GHz) with WPA3
– 8x RJ45 ports with PoE+ (802.3at), up to 30W per port
– Mixed speeds: 1x 10GbE port (uplink capable) + 2.5GbE on remaining ports (802.3bz)
– Total PoE budget up to 185W; device draw 25W
– Included 60W PSU limits available PoE to about 35W; optional 210W PSU recommended for full power
– Operating temperature: -30°C to +40°C
– Compact unit with on-device status display
Who it’s for
– Deployments where pulling cable is costly or impossible
– High-density venues that benefit from 6 GHz backhaul
– Installations needing multi-gig and PoE+ at the edge, such as cameras, APs, and smart building devices
Pricing and availability
The UDB Switch is available for a little over $299, with the optional 210W power supply priced at around $79. For most PoE-heavy builds, budgeting for the higher-wattage PSU will deliver the experience this wireless uplink switch is designed to provide.
