C9115AXI-E Description
Cisco C9115AXI-E is an indoor, controller-based Wi-Fi 6 access point with internal antennas, delivering 4×4:4 MIMO on both 2.4GHz and 5GHz. It implements uplink/downlink OFDMA, MU-MIMO, BSS Coloring, and Target Wake Time to boost efficiency, capacity, and client battery life in dense environments. Hardware includes a 2.5G mGig uplink (IEEE 802.3bz, Cat5e-ready), USB 2.0, RJ-45 console, and an integrated Bluetooth 5.0 radio. Power options include 802.3at PoE+ and Cisco UPOE(+); under 802.3af it runs in reduced-feature mode (2×2 both bands, 1G uplink, USB off). Operating range is 0–50°C; when ambient exceeds 40°C the AP shifts from 4×4 to 2×2, downgrades the uplink to 1G, and disables USB. C9115AXI-E works with Cisco Catalyst 9800 series and supported AireOS controllers (AireOS 8.9+; IOS-XE 16.11+).
