Core Technical Specifications and Target Use Cases
The Cisco Catalyst C9105AXIT-N is a Wi-Fi 6 (802.11ax) access point engineered for ETSI regulatory compliance in Europe, the Middle East, and Africa (EMEA). Key features include:
- ETSI-certified RF bands: Optimized for 5 GHz DFS channels (e.g., 52-64, 100-140) with adaptive radar avoidance
- 4×4:4 MU-MIMO on 5 GHz + 2×2:2 on 2.4 GHz: Delivers 2.1 Gbps aggregate throughput with OFDMA slicing
- Cisco CleanAir Pro®: Real-time spectrum analysis to detect/mitigate drones or industrial IoT interference
Designed for smart manufacturing floors and historic buildings with thick walls, it supports 220+ concurrent clients while maintaining ≤2% packet loss for latency-sensitive applications like AGV control systems.
Feature Comparison: C9105AXIT-N vs. C9105AXIT-A
| C9105AXIT-N | C9105AXIT-A | |
|---|---|---|
| Regulatory Domain | ETSI (EMEA) | FCC (Americas) |
| Max EIRP | 20 dBm (5 GHz) | 30 dBm (5 GHz) |
| DFS Channels | 24 (dynamic) | 60 (static) |
| PoE Requirement | PoE++ (60W) | UPOE (90W) |
| BLE/Zigbee | 5.2 + 3.0 | 5.1 + 3.0 |
The C9105AXIT-N prioritizes adaptive DFS agility for dense urban EMEA environments, whereas the AXIT-A focuses on high-power transmissions for large open spaces.
Critical but Underdocumented Configuration Nuances
Three often-overlooked operational considerations:
- LBT (Listen-Before-Talk) Compliance: Mandatory for unlicensed 5 GHz in EU; disables non-compliant features like beamforming during congestion
- Dual-5GHz Mode: Splits radio into 80+80 MHz channels (requires IOS XE 17.12.1+) for AR/VR workloads in museums
- Harsh Environment Kit: Optional IP55-rated enclosure for food processing plants (sold separately)
Procurement Guidelines via Itmall.sale
When purchasing the C9105AXIT-N, confirm:
- ETSI Declaration of Conformity: Included for EU customs clearance
- Cisco DNA Spaces Integration: Pre-configured for location analytics in retail/hospitality
- Advanced Replacement SLA: Next-business-day dispatch for EMEA time zones
Solving High-Density EMEA Challenges
The C9105AXIT-N addresses two region-specific Wi-Fi pain points:
- Dynamic Frequency Selection (DFS) Recovery: Resumes transmission in 45 seconds post-radar detection (vs. standard 60+ seconds), critical for real-time warehouse management
- Sub-1 GHz IoT Backhaul: Dedicated 802.11ah (Wi-Fi HaLow) radio for underground mining sensors, bypassing 2.4 GHz congestion
After deploying 80 units in a 15th-century European hotel chain, the adaptive antenna polarization consistently penetrated 1m stone walls—where competing APs required costly repeaters. While its 23 dBm power cap limits rural coverage, the Smart Channel Borrowing feature dynamically allocates bandwidth to high-priority SSIDs. Always pair it with Cisco Catalyst 9200L switches for end-to-end application visibility in hybrid work environments.
