The AP3915 is a feature rich 802.11ac Wave 2 and 802.11abgn indoor access point that delivers enterprise-grade performance and security without the premium cost. The AP3915i is designed to blend into any office, carpeted enterprise, or classroom environment. The AP3915 offers multiple connectivity options including 2.4G, 5G, and BLE/802.15.4 (e.g. Thread, etc.) for location services and extended connectivity to Internet of Things (IoT) sensors and devices.

The energy efficient AP3915 uses 802.3af Power over Ethernet (PoE) in normal operating mode. The AP3915e model requires professional installation and includes two RP-SMA antenna connectors supporting dual- band (2.4GHz/5GHz) band antennas, as well as a third RP-SMA connector for a 2.4G antenna for BLE/802.15.4 support. Unique to this class of product, the AP3915e is rated to operate in extended temperature ranges for deployments in gyms, pools, etc. that require specialized enclosures. An optional external power supply is available for deployments that do not support PoE.

The AP3915 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.
