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+).

Model Selection Guide – C9115AXI-E

  • Choose C9115AXI-E for high-efficiency Wi-Fi 6 in offices, schools, clinics, and enterprise floors that benefit from 4×4:4 radios and 2.5G mGig uplink on existing Cat5e cabling.
  • Prefer C9115AXE-E when you need external antennas (e.g., challenging RF or directional coverage) and wider temperature tolerance.
  • Consider C9115AXI-EWC-E if you want an Embedded Wireless Controller on-AP for simplified small/medium deployments without a separate controller.

Questions & Answers

  • How is the Cisco C9115AXI-E different from C9115AXI-R for multinational rollouts?

    Both are indoor Wi-Fi 6 APs with internal antennas; the difference is the regulatory domain “-E”. For global standards compliance, match each site’s domain to local regulations to ensure legal channels and transmit power.
  • Is C9115AXI-E a good fit for open-plan offices with many IoT devices?

    Yes. OFDMA improves efficiency for small, frequent IoT frames while MU-MIMO serves laptops and phones. Use separate IoT SSIDs with proper QoS and segmentation to keep latency predictable.
  • Does C9115AXI-E support CleanAir or RF analytics features?

    C9115 offers advanced RF telemetry and interference detection capabilities integrated with Catalyst 9800 and DNA Center. This helps locate non-Wi-Fi interferers and optimize channels automatically over time.
  • What mounting best practices apply to C9115AXI-E?

    Mount horizontally on ceilings for optimal pattern, keep clear of metal obstructions, and follow minimum distances from HVAC or lighting. Use plenum-rated accessories where required by building code.
  • Can C9115AXI-E deliver reliable voice over Wi-Fi?

    Yes, with proper design. Prioritize voice with WMM, enable fast roaming (802.11r/k/v where supported), and tune cell edges. Validate with call-quality tests before go-live.
  • What power and cabling are recommended?

    Provide PoE+ and Cat6/6A cabling for headroom. Ensure switch ports are configured for the voice/data VLANs and trust DSCP to keep QoS markings end-to-end.
  • How does C9115AXI-E compare with the C9105AXI series?

    C9115 generally delivers higher radio capability and throughput for denser environments. C9105 is more compact for hospitality or low/medium density spaces.
  • Is WPA3 transition smooth on C9115AXI-E?

    Yes. Use transition modes to support legacy clients while nudging modern devices to WPA3. Audit client capabilities first to avoid unexpected re-association behavior.
