Future ViabilityNearing EOL in modern applicationsWiFi 7 mainstream SoC over next 5+ years8. Summary and Selection GuidanceUse CaseRecommended SoC
Cost-sensitive, basic functionalityQCA9882 (mature and affordable)
Developing WiFi 7 products, mesh backhaul, or high performance CPEQCN6224 (tri-band, MLO, high concurrency)
OpenWiFi or TIP ecosystem integrationQCN6224
Legacy system replacementsQCA9882Additional Notes
QCN6224 is part of Qualcomm’s WiFi 7 platform lineup, designed for low-to-mid power WiFi 7 applications, offering tri-band support, 320MHz bandwidth, MLO, and efficient OFDMA scheduling.
QCA9882 remains popular in budget-friendly routers, industrial CPEs, and older wireless deployments but lacks future-facing features like 6GHz, MLO, or TWT.
