Full Commercial Product Description

Triple Concurrent Radio Architecture

1. 2.4 GHz 802.11ax Radio: 4×4:4 MU‑MIMO with four spatial streams, supports 20/40 MHz channel bandwidth, backward compatible with legacy 802.11b/g/n IoT and mobile devices, maximum single-band PHY throughput up to 1.2 Gbps.
2. 5 GHz 802.11ax Radio: Flagship 8×8:8 MU‑MIMO architecture with eight spatial streams, supports 20/40/80/160 MHz ultra-wide channels, DFS radar frequency avoidance, 1024-QAM high-efficiency modulation, peak single-band PHY throughput reaching 4.8 Gbps.
3. Embedded Bluetooth Low Energy 5.1 Radio: Native integrated IoT radio for indoor location analytics, asset tracking, proximity beacon marketing and low-power sensor connectivity, sharing internal antenna array without extra RF portsCisco.

• Uplink & Downlink OFDMA: Splits wireless spectrum into tiny resource units to drastically reduce multi-client transmission latency and improve spectrum utilization efficiency
• Downlink MU‑MIMO: Simultaneously transmits data to multiple Wi‑Fi 6 compatible clients to maximize airtime capacity in dense deployments
• BSS Coloring Spatial Reuse: Minimizes co-channel interference between adjacent access points in packed campus and auditorium layouts
• Target Wake Time (TWT): Extends battery service life of smartphones, tablets and battery-powered IoT sensors via scheduled sleep cycles
• Transmit Beamforming & MRC Maximal Ratio Combining: Extends wireless signal coverage range and strengthens connection stability for distant client devices

Integrated Internal Omnidirectional Antenna Array (AXI Core Feature)

• 2.4 GHz antenna gain: 4 dBi, full uniform 360° horizontal coverage
• 5 GHz antenna gain: 6 dBi, wide-area indoor coverage for open offices, lecture halls, stadium concourses and retail floors
  The integrated antenna design eliminates external RF cable installation, maintaining neat ceiling aesthetics while delivering balanced full-space coverage for general high-density indoor scenarios.

Hardware Interfaces & Power Specifications

Wired Interfaces

1. 1 × 100/1000/2500BASE-T Multigigabit (mGig) RJ45 uplink port, compliant with IEEE 802.3bz NBASE-T standard, transmitting data and receiving PoE power over a single Cat5e/Cat6 cable
2. RJ45 RS‑232 local console port for device configuration, firmware upgrade and field troubleshooting
3. USB 2.0 auxiliary port for local diagnostics and lightweight edge IoT application hosting
4. Multi‑color LED status indicator for boot state, WLC association, runtime operation and hardware fault alert
5. Physical reset button for one-touch factory configuration recovery
6. Kensington lock slot for physical anti‑theft protection

Power Supply Compatibility

• Primary required power: IEEE 802.3at PoE+ (30W power budget), mandatory to enable full 8×8 MIMO 5GHz radio performance and USB port activation
• Limited degraded operation via IEEE 802.3af PoE: When powered by af PoE, radios downgrade to reduced MIMO streams, Ethernet uplink speed drops to 1Gbps, and USB port is disabled to lower thermal load
• Compatible PoE injectors: AIR‑PWRINJ5 (802.3af), AIR‑PWRINJ6 (802.3at)

Supported Deployment Operation Modes

1. CAPWAP Lightweight Controller Mode: Centralized unified wireless policy management via Catalyst 9800 physical/virtual WLCs, global RF resource scheduling, seamless inter‑AP client roaming, centralized security enforcement and full Cisco DNA network analytics support.
2. EWC Embedded Wireless Controller Standalone Mode: Runs lightweight virtual wireless controller locally on EWC preloaded AP variants for independent large campus, auditorium or branch networks without dedicated physical WLC hardware.
3. Auxiliary diagnostic operational modes: Monitor Mode, Sniffer Mode for RF spectrum capture and wireless traffic analysis.

Enterprise‑Grade Wireless Security Suite

• WPA3‑Enterprise / WPA2 / WPA wireless encryption suites with AES hardware acceleration
• Secure Boot, runtime integrity defense, digital firmware image signing and hardware authenticity verification to block malicious firmware tampering
• Full 802.1X AAA authentication, complete EAP protocol suite (EAP‑TLS, PEAP, EAP‑FAST, EAP‑TTLS)
• Encrypted Traffic Analytics (ETA): Machine learning powered threat detection for encrypted traffic without decryption to identify ransomware and network intrusions
• MAC address filtering, isolated VLAN traffic segmentation for guest vs corporate/IoT networks, rogue AP detection and wireless intrusion monitoring
• Hardware‑accelerated DTLS tunnel encryption for CAPWAP controller communication links
