Wireless Access Point Cisco Catalyst 9120AXI-E Wi-Fi 6

The Cisco Catalyst 9120AXI-E is a Wi‑Fi 6 wireless access point designed for mission‑critical and high‑density deployments. It features dual 5 GHz radios with a 4x4 configuration, an integrated IoT radio, internal antennas and CleanAir technology powered by Cisco RF ASIC to improve radio‑frequency performance and interference mitigation. The device supports MU‑MIMO, Power over Ethernet and Ethernet LAN data rates up to 2500 Mbit/s, providing resilient connectivity for mobile and IoT devices when paired with Cisco DNA for analytics and automation.

Advantages

The Catalyst 9120AXI-E combines Wi‑Fi 6 performance with integrated security and RF intelligence. CleanAir with RF ASIC enhances spectrum visibility and reduces interference in crowded environments. Built‑in IoT radio support and Cisco DNA integration enable centralized management, real‑time analytics and faster threat detection. PoE support and a single RJ‑45 port simplify installation and power delivery.
