Cisco Catalyst C9120AXP Dual Band 802.11ax 5.38 Gbit/s Wireless Access Point - Indoor

The Cisco Catalyst 9120AXP Series Access Point is designed to redefine what an enterprise wireless network can deliver. Built for today’s dense device environments, it blends Wi‑Fi 6 performance with robust security, intelligent management, and resilient operation to keep your organization productive. Whether you’re equipping a corporate campus, a healthcare facility, or a large office with a high client count, the C9120AXP provides fast, reliable connectivity, strong security posture, and scalable management that grows with your network.

• Wi‑Fi 6 performance for dense environments: The C9120AXP supports dual‑band 802.11ax with 4x4 MU‑MIMO, OFDMA, and 1024‑QAM to deliver up to 5.38 Gbps aggregate throughput. This combination reduces latency, increases capacity, and speeds up critical applications as client devices multiply across campuses, hospitals, and large offices.
• Rock‑solid security and policy automation: Engineered with enterprise‑grade security, Secure Boot and Cisco Trust Anchor protect the device from tampering. Built‑in encryption, support for modern authentication, and integration with Cisco ISE and DNA Center empower consistent access control, robust threat containment, and automated policy enforcement across the wireless fabric.
• Intelligent RF management and interference mitigation: Cisco CleanAir features on the 9120AXP continuously analyzes the spectrum to identify interference sources and automatically adjusts radio settings. This intelligent RF optimization helps maximize airtime, minimize co‑channel interference, and sustain higher client throughput in challenging environments.
• High‑density, flexible indoor deployment: With a compact indoor form factor designed for ceiling- or wall‑mounting, the C9120AXP is ideal for conference rooms, workspaces, and hospital corridors where space is at a premium. The access point supports flexible power options, including PoE+ (IEEE 802.3at), making installation clean and scalable as your network footprint expands.
• Smart management, analytics, and lifecycle support: This AP is built to work with Cisco’s management ecosystem, enabling zero‑touch provisioning, centralized policy, real‑time analytics, and firmware updates that keep security and performance current. Integrated telemetry helps network operators understand client experience, roaming performance, and application behavior across the wireless network.
