The AP3912 is a feature rich 802.11ac Wave 2 and 802.11abgn indoor access point that delivers enterprise-grade performance and security for small service areas such as residence halls, patient rooms, or hotel rooms. Although simple to install, the AP3912 offers a range of connectivity options including wired LAN, 2.4/5G WiFi, and wired pass-through and comes future proof with an integrated BLE/802.15.4 radio for connectivity to Internet of Things (IoT) sensors and devices.

The energy efficient AP3912 uses 802.3af Power over Ethernet (PoE) in normal operating mode. For deployments that require powering a wired device upstream such as an IPTV or VOIP phone, the AP3912 can optionally provide 802.3af power to a wired device when powered via 802.3at PoE+ by a downstream switch.

The AP3912 is built using the latest Wi-Fi technology, including 802.11ac Wave 2, dynamic radio management, spectrum analysis with interference classification, beamforming, multi-user MIMO, self-forming and self-healing meshing, security, role-based authentication, authorization, and access control. The 2×2:2 platform is capable of delivering up to 1.2 Gbps over-the-air performance and up to 50,000 packets per second on the wire port.
