Sorry, this product is no longer available, please contact us for a replacement.



The AP3705i is a feature-rich 802.11abgn access point leveraging the newest radio technology to reduce cost without sacrificing functionality. Designed to blend into office, classroom, or hotel environments, the AP3705i is ideal for providing secure 11abgn connectivity for high-density environments such as schools, hotels, and conference centers. The 3705i comes packed with the latest in WiFi technology including dynamic radio management, beamforming, spectrum analysis with interference classification, self-forming and self-healing meshing, security, role-based authentication, authorization, and access control. Optimized for drop ceiling deployments, the 2x2:2 platform is equipped with an integral four antenna array with beamforming, capable of supporting 600Mbps over-the-airperformance and up to 40,000 packets per second on the wire port. The 3705i comes with integral clips allowing the AP to be installed directly onto most drop ceilings right out-of-the-box. This green AP uses less than 9W of power fully loaded and includes the Extreme Networks Lifetime Warranty making it the best value in the industry!

  • Easy and cost-effective migration path to 802.11n
  • Comprehensive wireless security services for authentication, encryption, IPS, and NAC
  • Flexible architecture supports centralized and/or distributed traffic forwarding for voice/video/data applications
  • Policy enforcement and rate limiting at the AP support diverse deployments
  • Unified wired/wireless role-based access control with guest networking

Extreme Networks Wireless APs use the most sophisticated standards to ensure effective security and client compatibility. Using the 802.11i (WPA2) standard, wireless LAN deployments can utilize 802.1X or PSK authentication and AES, TKIP, or WEP encryption. These options ensure secure authentication and seamless integration of the APs with the wired network infrastructure.

Extreme Networks Wireless APs work together to prevent interference and optimize RF sharing. Each AP is able to intelligently and dynamically adjust its transmit power and channel based on information related to neighboring APs as well as external interference or channel occupation. This ensures optimal performance for all wireless clients. If an AP fails, neighboring APs will increase power to maintain coverage in the affected area. The APs also support RF channel plan selection with the option of supporting 3-channel, 4-channel or a fully custom configuration.
