Product Overview

The Cisco Catalyst C9115AXI-B is an enterprise-class indoor Wi-Fi 6 access point with integrated antennas and dual-band 2.4 GHz/5 GHz operation. It supports 4x4 MIMO with four spatial streams, OFDMA, MU-MIMO, and multigigabit Ethernet for business, campus, healthcare, education, and high-density wireless deployments.

Key Performance Features

• Wi-Fi 6 / IEEE 802.11ax wireless technology
• Simultaneous dual-band 2.4 GHz and 5 GHz operation
• 4x4 MIMO with four spatial streams
• Uplink and downlink OFDMA
• MU-MIMO support
• BSS coloring for improved spatial reuse
• Target Wake Time support
• Up to 160 MHz channel width
• Maximum PHY data rate up to 5.38 Gbps
• Integrated omnidirectional antennas
• 100/1000/2500 Mbps Multigigabit Ethernet interface
• WPA3, WPA2, 802.1X, and AES security support

Technical Specifications

Cisco specifies the 9115AXI as the internal-antenna version and lists its multigigabit Ethernet, USB, security, antenna, and wireless capabilities in the official documentation.

Compatibility

Designed for Cisco enterprise wireless environments. Cisco lists compatibility with Catalyst 9800 Series Wireless Controllers and certain Cisco 3500, 5520, 8540, and Virtual Wireless Controller platforms when running supported software releases. Cisco specifies Cisco Unified Wireless Network Software 8.9 or later and IOS XE 16.11 or later in the product data sheet.

Important Compatibility Notice

C9115AXI-B is a regulatory-domain-specific model. Regulatory approval must match the country in which the AP will be deployed; Cisco requires customers to verify the appropriate regulatory domain before installation.

This standard C9115AXI model is controller-based. Do not assume it is the Embedded Wireless Controller version; those models use the separate C9115AXI-EWC-x designation.

For full 4x4 operation, appropriate PoE should be used. Cisco notes that use of the lower-power AIR-PWRINJ5 / 802.3af configuration reduces both radios to 2x2, limits Ethernet to 1 GbE, and disables USB.
