Unlike traditional enterprise Wi-Fi systems that require an on-premise hardware controller, the UniFi controller is software that can be deployed on-site using a PC, Mac, or Linux machine; or off-site in a private cloud or a public cloud service. The UniFi 802.11AC Dual-Radio APs feature the latest in Wi-Fi 802.11AC MIMO technology. Using the UniFi Controller software, configure and manage your APs with the easy-to-learn user interface. Finally, take advantage of the unlimited scalability: build wireless networks as big or small as needed. Start with one (or upgrade to a four‑pack or five) and expand to thousands while maintaining a single unified management system.
