About the Cisco Aironet 3900 Wireless Access Point WS-AP3915I-ROW

The Cisco wireless AP WS-AP3915I-ROW delivers IEEE 802.11a/b/g/n/ac (Wave 1) performance across concurrent dual-band operation on 2.4 GHz and 5 GHz frequencies, positioning this access point as a proven mid-tier solution for enterprise indoor deployments. Built on the Cisco Aironet 3900 series platform, the WS-AP3915I-ROW features 2x2 MIMO with 2 spatial streams and internal omnidirectional antennas powered by dual independent radios—one per band. Power delivery via PoE (802.3af / 802.3at) over its single 10/100/1000 Mbps Ethernet interface simplifies installation in ceiling-tile and wall-mounted environments. Cisco CleanAir technology mitigates RF interference, while WPA2-Enterprise, 802.1X, and AES encryption provide layered security for mission-critical networks.

Network engineers and IT procurement teams responsible for medium-density indoor coverage—including office buildings, campuses, and light-to-moderate density retail or hospitality venues—standardize on this model for its balance of performance, reliability, and operational cost. The WS-AP3915I-ROW operates as a controller-based access point, integrating seamlessly with Cisco Wireless LAN Controller deployments and offering centralized management through Cisco Prime Infrastructure or Cisco DNA Center. Its operating temperature range of 0°C to 40°C (32°F to 104°F) supports diverse climates across the Rest of World (ROW) regulatory domain, while included mounting hardware accelerates deployment cycles.
