Ponto de acesso sem fios Cisco Catalyst 9120AXI-EWC-E Wi-Fi 6

The Cisco Catalyst 9120AXI-EWC-E Wireless Access Point Cisco Catalyst 9120AXI-EWC-E Wi-Fi 6 provides enterprise-grade wireless connectivity based on the IEEE 802.11ax standard. It features 4x4 dual 5 GHz radios, support for 2.4 GHz and 5 GHz bands, MU-MIMO, and integrated CleanAir technology powered by Cisco RF ASIC. The access point supports strong authentication and encryption algorithms including 802.1x RADIUS, AES, WPA, WPA2 and WPA3, and delivers Ethernet LAN data rates up to 2500 Mbit/s with Power over Ethernet (PoE) support. The unit is designed for high-density, mission-critical deployments and integrates IoT radio capabilities together with platform features for analytics and security.

Advantages

The Catalyst 9120AXI-EWC-E combines Wi‑Fi 6 performance with RF intelligence to reduce interference and improve capacity in crowded environments. CleanAir technology detects and mitigates RF issues at the hardware level, while MU-MIMO and dual 5 GHz radios increase concurrent client throughput. Built-in security features and compatibility with Cisco DNA enable centralized management, real-time analytics and automated policy enforcement across the wireless network.

How to use

Install the access point on a ceiling or wall mount according to site planning and cabling guidelines, connect the device to a PoE-enabled switch or injector using an Ethernet cable, and provision it through the chosen Cisco management platform. Configure SSIDs, security policies (including 802.1x and WPA3 where applicable), radio settings and any IoT integration settings. Use site surveys or controller-based tools to optimise channel plan and transmit power for the deployment environment.

Recommendations

For best performance in high-density deployments enable Wi‑Fi 6 features, use CleanAir-driven interference mitigation, and integrate the access point with Cisco DNA or a compatible controller for centralized analytics and automated policy enforcement. Ensure PoE provisioning meets the maximum power consumption requirement and follow recommended placement and RF planning practices.
