Cisco Catalyst 9115AXI-B Wireless Access Point, Wi-Fi 6, 4×4 MU-MIMO, Controller Managed, PoE, Internal antenna, (C9115AXI-B)

The Cisco Catalyst 9115AXI-B is an enterprise-grade indoor wireless access point from Cisco’s 9115AX Series. It supports Wi-Fi 6 (802.11ax) with 4×4 MU-MIMO for high-performance, multi-device connectivity and includes an internal antenna configuration in the B regulatory domain. Designed for controller-managed networks, it delivers faster, more efficient wireless access with features like OFDMA, multigigabit Ethernet, and Bluetooth Low Energy (BLE) support for location-based services.

Key Features

• Wi-Fi 6 (802.11ax) support — Dual-band 2.4 GHz and 5 GHz radios with OFDMA and MU-MIMO to improve throughput and efficiency in busy networks.

• 4×4 MIMO with four spatial streams for enhanced performance.

• Maximum PHY data rate up to ~5.38 Gbps (combined across radios) under optimal conditions.

• Integrated BLE 5.0 — Bluetooth Low Energy radio for location-based services such as asset tracking.

• Internal omnidirectional antennas — Simplifies installation for typical indoor coverage needs.

• Multigigabit Ethernet — Includes 1×2.5 GbE (802.3bz) for higher throughput backhaul.

• Powered by PoE — Supports PoE+, Cisco UPOE (or standard PoE with limitations).

• Controller management — Designed to operate with Cisco wireless LAN controllers (e.g., Catalyst 9800 Series) rather than as a standalone consumer AP

• Interfaces & Connectivity

  • Ethernet: 1× 100/1000/2500 Mbps multigigabit RJ-45 uplink (802.3bz).

  • Management: RJ-45 console port.

  • USB: USB 2.0 (future enablement subject to software support).

  • Power: PoE+ (802.3at); supports Cisco UPOE / 802.3bt – enhances power for full performance.

• Performance & Processing

  • Memory: 2048 MB DRAM; 1024 MB flash.

  • Controller Support: Works with Cisco Catalyst 9800 Series and other Cisco WLAN Controllers; runs Cisco unified wireless network or Cisco IOS XE software.

• Physical & Environmental

  • Dimensions: ~20.3 × 20.3 × 3.8 cm (8.0 × 8.0 × 1.5 in).

  • Weight: ~0.9 kg (2 lb).

  • Operating Temperature: 0 °C to 50 °C (32 °F to 122 °F).

  • Humidity: 10 % to 90 % non-condensing.

  • Transmit Power: Up to ~23 dBm on both 2.4 GHz and 5 GHz
