The Ubiquiti UniFi Cloud Gateway Ultra (UCG-Ultra) is a compact and powerful all-in-one networking device designed for small to medium-sized networks. It combines the functions of a gateway, firewall, and router with a built-in UniFi Controller, making it an ideal central hub for managing a UniFi network.

Key Features and Specifications

• All-in-One Solution: The UCG-Ultra is unique because it includes a built-in UniFi Network Controller. Unlike older UniFi gateways (like the USG series), you don't need a separate Cloud Key or a dedicated server to manage your UniFi access points, switches, and other devices. This simplifies the entire network setup and management process.

• Performance: It is a high-performance device capable of handling network traffic efficiently. It can support up to 10 UniFi devices and 100+ clients, making it suitable for a wide range of environments.

• Wired Connectivity: It has four Gigabit Ethernet ports. One port is the WAN (Internet) input, while the other three are LAN ports for connecting devices.

• Form Factor: The UCG-Ultra has a very compact and sleek design. It is passively cooled (fanless), ensuring silent operation, and its small size allows it to be placed discreetly on a desk or shelf.

• Management: It is managed through the UniFi Controller software, which you can access via a web browser or the UniFi mobile app. The controller provides a powerful, single-pane-of-glass interface for monitoring network performance, configuring firewall rules, setting up VPNs, and managing all connected UniFi devices.
