Qualcomm QCA6688: Kfz-Wi-Fi 6 + Bluetooth 5.3 Combo -Modul

The rapid evolution of smart cockpits has elevated in-vehicle wireless connectivity from a supporting feature to a core experience. High-definition screen projection, multi-device concurrency, Bluetooth calling, OTA updates: every application demands greater bandwidth, stability, and integration from wireless modules. Jedoch, traditional discrete deployments of separate Wi-Fi and Bluetooth -Module bring a host of issues: antenna interference, PCB space constraints, and complex driver integration.

A highly integrated WiFi combo module, combining Wi-Fi and Bluetooth in a single package, is becoming the mainstream choice for automotive wireless design. Feasycom FSC-BW5048QV is an automotive-grade WiFi combo module designed for exactly this purpose. It integrates 802.11ax W-lan 6 und Bluetooth 5.3, is built on the Qualcomm QCA6688 chipset, and meets AEC-Q100 automotive standards, providing a stable and efficient wireless connectivity foundation for smart cockpits.

ICH. Why Choose a WiFi Combo Module?

The core pain points of discrete module solutions are:

• Co-channel interference: Two modules sharing the 2.4 GHz band lead to unavoidable antenna-to-antenna interference.
• Cost and time: Separate sourcing and tuning increase both BOM cost and development cycles.
• Integration complexity: Different driver frameworks from different vendors add significant system integration burden.

A WiFi combo module solves these problems at the architectural level: unified antenna design reduces co-channel interference, a single module meets automotive reliability requirements, and integrated drivers and protocol stacks are delivered together, dramatically lowering integration difficulty.

III. Key Application Scenarios

1. In-Vehicle High-Speed Wi-Fi Hotspot for Multiple Smart Devices

Passengers expect seamless connectivity for tablets, Laptops, gaming consoles, and other smart devices during travel. The module supports Access Point (AP) Modus, acting as a central in-car Wi-Fi hotspot capable of connecting multiple clients simultaneously. Mit W-lan 6 OFDMA and 2×2 MU-MIMO, it efficiently allocates bandwidth across all connected devices to prevent congestion.

The module also supports Dual-Band Simultaneous (DBS) operation, allowing 2.4 GHz und 5 GHz bands to work concurrently to distribute traffic load and minimize interference between devices.

2. Low-Latency Wireless Smartphone Projection

Wireless projection relies on a low-latency, high-reliability link between the smartphone and the head unit. The module’s PCIe Gen 3 interface provides the high bandwidth and low-latency data path required for smooth screen mirroring and responsive touch interaction. With advanced coexistence handling between Wi-Fi and Bluetooth, drivers can use wireless projection for navigation and streaming without interference from a simultaneous Bluetooth hands-free call.

The module’s automotive-grade construction guarantees stable operation under the temperature extremes and vibration typical of in-vehicle environments, making it a suitable hardware foundation for infotainment systems.
