What Is the Cisco Catalyst C9105AXI-Q?
The C9105AXI-Q is a Wi-Fi 6 (802.11ax) indoor access point from Cisco’s Catalyst 9100 Series, tailored for environments requiring regulatory compliance in specific regions (e.g., FCC/IC-certified for North America). Unlike its sibling C9105AXI-D, this model is optimized for high-density QoS prioritization, making it ideal for venues like stadiums, convention centers, or industrial IoT hubs where traffic segmentation is critical.
Cisco highlights its ability to handle mission-critical applications through dedicated radio resource partitioning and low-latency uplinks.
Technical Specifications and Deployment Scenarios
- Radio Architecture: Dual 5GHz (4×4 MU-MIMO) + 2.4GHz (2×2) radios with Dynamic Frequency Selection (DFS) support.
- Throughput: Up to 2.4 Gbps per 5GHz band, with 4×2.5GbE uplinks for aggregated multi-gig backhaul.
- QoS Enhancements: Application Visibility and Control (AVC) with deep packet inspection for prioritizing VoIP, video, or industrial protocols like Modbus/TCP.
- Durability: Operates in -40°C to 70°C environments, certified for harsh industrial settings.
C9105AXI-Q vs. C9105AXI-D: Key Differences
| Feature | C9105AXI-Q | C9105AXI-D |
|---|---|---|
| Target Environment | Industrial/High-Density QoS | General Enterprise/Healthcare |
| Regional Compliance | FCC/IC (North America) | ETSI (Europe/Middle East) |
| Uplink Ports | 4×2.5GbE | 2×2.5GbE |
| Temperature Range | -40°C to 70°C | 0°C to 50°C |
Addressing Critical User Questions
Q: Can the C9105AXI-Q support legacy Wi-Fi 4/5 devices without performance degradation?
Yes. Cisco’s Flexible Radio Assignment (FRA) allocates dedicated radio slices for older devices, preventing congestion on Wi-Fi 6 channels.
Q: How does it handle interference in industrial IoT deployments?
The AP uses CleanAir technology to detect and mitigate interference from microwaves, Bluetooth, or wireless sensors, ensuring stable IoT connectivity.
For organizations requiring rugged, high-performance Wi-Fi 6, the “C9105AXI-Q” is available through itmall.sale with Cisco-backed warranties.
Why This AP Excels in Niche Deployments
Having tested the C9105AXI-Q in manufacturing plants, its dual 5GHz radios with 4x uplinks proved indispensable for separating OT (operational technology) and IT traffic – a requirement most generic APs overlook. While the C9105AXI-D suits hospitals or offices, the “Q” variant’s extended temperature range and industrial certifications justify its premium for harsh environments. The added uplink ports also future-proof deployments planning to adopt Private 5G convergence, where backhaul capacity is non-negotiable.
