The AP3917 is a feature rich 802.11ac Wave 2 and 802.11abgn outdoor access point that extends affordable enterprise-grade mobility beyond the walls. These outdoor access points are designed to operate in harsh environments such as manufacturing plants, parks, practice facilities, and outdoor stadiums. The AP3917 offers multiple connectivity options including WiFi 2.4GHz, WiFi 5GHz, and BLE/802.15.4 (e.g. Thread, etc.) for location services or extended connectivity to Internet of Things (IoT) sensors and devices.

The energy efficient AP3917 is powered via 802.3at Power over Ethernet (PoE). The light-weight and compact design enables easy installation on most surfaces; optional accessories are available for fixed wall mounting, directional wall mounting, or pole mounting. The AP3917e model requires professional installation and includes four standard N-type antenna connectors supporting 2.4GHz or 5GHz band antennas, as well as a fifth standard N-type connector for a 2.4GHz antenna for BLE/802.15.4 support.

The AP3917 is built using the latest in 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 to ensure consistent and secure connectivity to users and sensors. The 2×2:2 platform can deliver up to 1.2 Gbps over-the-air-performance and up to 50,000 packets per second on the wired port using a unique flow-based architecture that provides consistent performance even when enforcing extensive application-based (aka Layer 7) service requirements.
