The Extreme Networks WS-AP3935i is part of the ExtremeWireless™ 3935 i/e series, an enterprise-grade indoor access point offering ultra-high performance for demanding high-density deployments. Below is a detailed product description based on search results:

Product Overview

The Extreme WS-AP3935i is a feature-rich 802.11ac (Wave 2) and 802.11abgn indoor access point that delivers enterprise-grade performance and security. Designed to seamlessly integrate into offices, classrooms, lecture halls, or large common areas, the WS-AP3935i is ideal for providing secure 802.11ac and 802.11abgn connectivity in high-density, mission-critical environments such as schools, universities, hospitals, indoor arenas, and conference centers. The WS-AP3935i comes with an integrated eight-port antenna array for easy installation. It utilizes 802.3at Power over Ethernet (PoE+) to achieve maximum performance and can operate within an 803.2af power budget, though with reduced performance. Its Ethernet ports support transparent power transition (PoE Hot-swap). In the event of power interruption to one port, the AP automatically switches to the other port without rebooting or interrupting its state. An optional external power supply is available for deployments that do not support Power over Ethernet.

Key Features and Benefits

  • High Performance: Built on the latest Wi-Fi technology, including 802.11ac Wave 2, dynamic radio management, spectrum analysis with interference classification, beamforming, multi-user MIMO, and self-forming and self-healing meshing. The 4×4:4 platform delivers up to 2.5 Gbps over-the-air performance and up to 90,000 packets per second on the wired port.
  • Flexible Deployment: The WS-AP3935i can be directly mounted on flat surfaces or installed on most drop ceilings using the included tool-less drop ceiling bracket. Multiple antenna configurations (e.g., Omni, sector, and panel) ensure optimal coverage and capacity for deployment needs.
  • Advanced Security: Supports multiple security algorithms, including WPA, WPA2-AES, 802.1x RADIUS, IPSec, SSL/TLS, etc. Features integrated management, security, and QoS capabilities to reduce operational costs while ensuring a consistent user experience across locations.
  • Seamless Roaming: Enables seamless roaming across an entire multi-subnet campus without requiring cumbersome client software. Supports fast secure roaming and handover between APs (802.11r), pre-authentication, opportunistic key caching (OKC), and more.
  • Quality of Service (QoS): Supports WMM, 802.11e QoS, power save mode (U-APSD), rate limiting (rule and user-based), rule and role-based QoS processing, multicast rate control, and multicast-to-unicast conversion.
