Qualcomm’s Next-Gen Wi-Fi 7: FastConnect C7700/QCC2072

Qualcomm has officially launched the FastConnect C7700 product series this year, refining and optimizing features compared to the previously released FastConnect C7800.

As shown in the specifications, the QCC2072 adopts a single PHY design, omitting the DBS/HBS functionality found in dual-PHY configurations. The chip integrates a high-performance PA, further reducing costs.

Wi-Fi 7 Enhancements

Beyond supporting Wi-Fi 7’s 320MHz bandwidth and 5.8Gbps peak throughput, the QCC2072 also features eMLSR MLO (Enhanced Multi-Link Single Radio). If interference occurs on one frequency band, eMLSR enables seamless data transmission via alternate links, enhancing reliability. As a key Wi-Fi 7 MLO upgrade, eMLSR ensures high throughput and low latency even in congested environments, significantly improving user experience.

Wi-Fi Aux Radio – Advanced Power Management

Qualcomm’s new Wi-Fi Aux Radio optimizes power efficiency by monitoring TX/RX states and intelligently toggling transmission modes. It also performs low-latency background scanning, minimizing impact on active communication throughput while maintaining transmission quality and reducing Wi-Fi power consumption.

Bluetooth 6.0 Dual-Mode Support

The chip supports dual-mode Bluetooth (BLE 6.0) with dual-antenna TX/RX MRC (Maximal Ratio Combining), improving interference resistance and signal reception in multipath environments.

Design Focus: Cost-Effective Client-Side Optimization

The FastConnect C7700/QCC2072 prioritizes STA (client-side) functionality while lowering chip costs, paving the way for broader industry adoption.

QOGRISYS specializes in delivering cutting-edge IoT connectivity solutions. We’ve previously released Qualcomm Wi-Fi 6E modules (O2066PM/O2066PB) and Wi-Fi 7 modules (O7851PM). Our next-gen Wi-Fi 7 modules (O2072PM/O2072PB) will launch soon—stay tuned for updates!
