The Cisco Catalyst 9115AXI (C9115AXI-E) is a professional, dual-radio Wi-Fi 6 (802.11ax) indoor access point for enterprise campus, office, retail, education, and hotel environments. It offers a combined maximum data rate of up to 5.38 Gbps (4.8 Gbps in the 5 GHz band and 574 Mbps in the 2.4 GHz band) and supports up to 256 simultaneous client connections per radio module. The access point features integrated 4x4:4 (5 GHz) and 4x4:4 (2.4 GHz) MU-MIMO omnidirectional antennas with an antenna gain of 6 dBi (5 GHz) and 5 dBi (2.4 GHz).

The Catalyst 9115AXI supports all essential Wi-Fi 6 features, including OFDMA (Orthogonal Frequency Division Multiple Access), MU-MIMO (Multi-User MIMO), 1024-QAM, Target Wake Time (TWT) for energy-efficient IoT devices, and BSS coloring for optimized radio performance in dense environments. For security, it supports WPA3, WPA2, WPA, OWE (Opportunistic Wireless Encryption), and 16 BSSIDs per radio module.

The access point features integrated Bluetooth 5.0 Low Energy (BLE) radio modules for IoT applications such as location tracking, asset tracking, beacons, and sensors. It can be powered via PoE (802.3at/802.3bt) or an external 54 V DC power supply and offers a 10/100/1000/2.5G BASE-T RJ-45 uplink port (mGig), a USB 2.0 port, and a console port for local management.

The Catalyst 9115AXI supports multiple operating modes: controller-based (CAPWAP, with Cisco Catalyst 9800 wireless controllers), controllerless (Embedded Wireless Controller, EWC), and cloud management via Cisco DNA Center. It is designed for ceiling, wall, or pole mounting and comes with a limited lifetime hardware warranty.
