Cisco Aironet 3702I IEEE 802.11ac 450 Mbit/s Wireless Access Point

The Cisco Aironet 3702I is a premier indoor wireless access point engineered for enterprise environments that demand exceptional reliability, scalable management, and strong performance in high-density scenarios. Built on the IEEE 802.11ac standard, this device is designed to deliver a superior High Density Experience (HD Experience) by intelligently handling large numbers of clients, enabling smooth video, voice, and data traffic even when the office, campus, or retail floor is teeming with devices. It combines Cisco’s trusted security features with enterprise-grade management, giving IT teams a robust and future-ready foundation for wireless networks. Whether deployed in a university building, a corporate headquarters, or a multisite service provider network, the 3702I is designed to maximize user satisfaction, reduce support calls, and simplify ongoing operations through streamlined provisioning and policy control. The result is a scalable, resilient, and efficient wireless solution that aligns with modern digital workstyles and the growing demand for reliable mobility.

• HD Experience in High-Density Deployments: This access point is engineered to sustain performance as client counts rise. It maintains steady throughput for business-critical applications, supporting high-definition video meetings, real-time collaboration, and cloud-based workloads without the usual slowdowns that plague crowded networks. By leveraging sophisticated radio tech and intelligent interference mitigation, it minimizes dropped connections and latency, ensuring a consistent experience across classrooms, offices, and conference spaces.
• True 4x4 MIMO with Three-Spatial-Stream Capabilities: The 3702I is built to maximize capacity and coverage in dense environments. With four transmit/receive paths and support for three spatial streams, it offers improved multi-user efficiency and stronger signal robustness for devices across the floor. This configuration helps more clients enjoy higher data rates simultaneously, which translates into faster file transfers, snappier app performance, and better roaming behavior as users move between APs.
• IEEE 802.11ac Speeds with Backward Compatibility: The 3702I taps into the higher throughput of 802.11ac while remaining compatible with legacy devices. This enables a smoother upgrade path for organizations, delivering faster performance for capable devices and preserving access for older laptops, smartphones, and IoT gear. The result is a balanced network that evolves with your equipment pool without forcing disruptive replacements.
• Seamless Cisco Ecosystem Integration: Designed to work harmoniously with Cisco Wireless LAN Controller (WLC) environments and DNA Center, the 3702I simplifies centralized management, policy enforcement, and secure firmware updates. IT teams gain a unified view of the wireless fabric, with streamlined commissioning, monitoring, and troubleshooting across hundreds or thousands of APs. This integration supports consistent security posture, quality of service (QoS), and guest access controls throughout the organization.
• Energy-Efficient and Flexible Deployment: Optimized for modern offices and public spaces, the 3702I supports Power over Ethernet (PoE), reducing clutter and minimizing cabling complexity. Its compact indoor form factor is suitable for ceiling or wall mounting, delivering quiet operation and unobtrusive aesthetics in classrooms, retail storefronts, hospital corridors, and corporate lounges. The device is designed to run reliably in typical office temperatures and humidity ranges, with built-in protections that help sustain uptime in demanding environments.

How to install Cisco Aironet 3702I

• Plan your placement with a site survey to identify optimal locations, minimize interference, and ensure even coverage across the intended area. Consider high-traffic zones, conference rooms, and common areas to determine where access points will deliver the most value.
• Mount the AP securely on a ceiling or wall using the included hardware. Ensure there is adequate airflow around the device to prevent overheating and maintain consistent performance over time.
• Connect the Ethernet cable to a PoE-enabled switch or power injector. Verify that the switch port supports at least PoE (IEEE 802.3af) or PoE+ (IEEE 802.3at) to supply sufficient power to the AP.
• Adopt and configure the AP through your Cisco WLC or DNA Center. Define SSIDs, security policies, VLAN tagging, and guest access rules. Apply QoS settings to prioritize voice, video, and critical business apps as needed.
• Test and validate performance after deployment. Run throughput tests, roaming checks, and channel optimization to ensure consistent client experiences, then schedule firmware updates and monitor health through the centralized management platform.
