Cisco Catalyst C9115E Indoor Wi-Fi 6 AP — 5.38 Gbps Dual-Band Enterprise Access Point with Cisco CleanAir Technology

The Cisco Catalyst C9115E is engineered for today’s densely populated enterprise environments, delivering robust, scalable Wi‑Fi 6 connectivity that enhances performance for mobile devices, IoT sensors, and bandwidth‑hungry applications. Built for indoor deployments, this dual‑band access point combines advanced radio technologies with Cisco DNA‑enabled management to provide reliable coverage, seamless roaming, and centralized security across campus networks. With its 5.38 Gbit/s aggregate data rate, the C9115E is designed to support high user density, mission‑critical workloads, and evolving business needs without compromising reliability or security.

• Powerful Wi‑Fi 6 performance: The C9115E operates in dual bands (2.4 GHz and 5 GHz) and leverages 802.11ax with OFDMA, MU‑MIMO, and 1024‑QAM to maximize throughput. The result is higher per‑user speeds, more efficient spectrum use, and lower latency even in crowded environments, making it ideal for classrooms, office floors, and hospitality spaces.
• High‑density coverage with intelligent interference mitigation: Cisco CleanAir technology analyzes radio frequency conditions in real time to identify interference sources and optimize channel selection. The access point delivers airtime fairness and smart roaming features to maintain stable connections as users move across spaces, reducing dropped sessions and reauths.
• Enterprise‑grade security and policy control: Built with robust security capabilities, the C9115E supports WPA3‑Enterprise, 802.1X authentication, and centralized policy enforcement. Seamless guest access, secure onboarding, and device isolation help protect sensitive data while delivering a smooth guest experience.
• Seamless management and scalable deployment: Designed for Cisco DNA Center and Catalyst ecosystems, the C9115E enables zero‑touch provisioning, automated firmware updates, and centralized analytics. This makes it easier to deploy at scale, monitor performance, and implement consistent security policies across multiple sites.
• Flexible power and discreet indoor form factor: The access point is designed for ceiling mounting in indoor environments and supports PoE+ (IEEE 802.3at), simplifying installation and reducing cable clutter. Its compact profile blends with most interiors while delivering enterprise‑grade performance and reliability.

how to install Cisco Catalyst C9115E

• Plan your deployment with a site survey to identify high‑density zones, potential RF interference sources, and optimal mounting locations for uniform coverage across the space.
• Prepare the network: verify PoE+ availability on the switch or injector, confirm firmware compatibility with your Cisco DNA Center environment, and ensure remote management settings are ready for zero‑touch provisioning.
• Mount the access point in a suitable indoor location using the included ceiling‑mount hardware. Position it away from metal objects, large glass panes, and other obstructions to maximize signal propagation and minimize interference.
• Connect the AP to a PoE+ port with a standard Ethernet cable, power up, and verify link status. Use the management console (DNA Center or Catalyst switches) to adopt the device and apply baseline configurations such as SSIDs, security policies, and guest access settings.
• Configure wireless services and security policies: create enterprise and guest SSIDs, enable appropriate authentication methods, set QoS policies, and enable features like captive portal for guests. Run a post‑deployment performance test to validate coverage and adjust transmit power or channel allocations as needed.
