As the demand for IoT, smart manufacturing, HD video streaming, and remote work continues to rise, WiFi technology has become the backbone of modern connectivity. The upgrade from WiFi 5 (802.11ac) to WiFi 6 (802.11ax) is no longer optional—it’s essential. Qualcomm’s QCA9880 was once a star in the WiFi 5 era, while the QCN9024 stands as a powerful representative of WiFi 6 with significantly improved efficiency and performance.
This article provides a detailed analysis of why migrating from QCA9880 to QCN9024 is a necessary and strategic move, exploring technical performance, system efficiency, deployment flexibility, application scenarios, future compatibility, and ROI.

2. Enhanced System EfficiencyWiFi 6 introduces several key technologies—OFDMA, TWT, and BSS Coloring—which allow QCN9024 to maintain stable performance in dense deployments, whereas QCA9880 struggles under load.
- OFDMA (Orthogonal Frequency Division Multiple Access) : Splits channels into smaller subcarriers, enabling multiple devices to transmit simultaneously and efficiently.
- TWT (Target Wake Time) : Reduces power consumption by scheduling wake times for devices—ideal for IoT scenarios.
- BSS Coloring: Differentiates overlapping signals from neighboring APs, minimizing co-channel interference.
3. Greater Deployment Flexibility & MaintainabilityQCN9024 supports PCIe 3.0, has open-source driver support via ath11k, and is compatible with major Linux systems, making it ideal for:
- Embedded gateways (OpenWRT/OpenWiFi)
- Enterprise-grade APs
- Industrial IoT devices
- High-performance wireless backhaul (Mesh/PtP)
It also enables advanced RF tuning and signal optimization for more efficient wireless coverage.
4. Broader Industry ApplicationsIndustryUpgrade Advantages

5. Future Compatibility & ROI Assurance- Device Ecosystem: Most modern phones, laptops, and IoT devices now support WiFi 6—QCN9024 unlocks their full potential.
- Mature Software Support: ath11k drivers are stable and well-supported in modern Linux kernels and open-source platforms.
- Long-Term Availability: QCA9880 is nearing EOL (End of Life), while QCN9024 offers a clear roadmap and continued vendor support.
6. Conclusion: More Than a Replacement—A Complete RebuildWhile QCA9880 has served well, its limitations are increasingly evident under modern network demands. QCN9024 doesn’t just “replace” QCA9880—it rebuilds the wireless experience from the ground up, offering:
- Stronger market competitiveness
- Superior user experience
- Lower OPEX and support costs
- Better long-term investment returns
The next generation of wireless begins with QCN9024.
