Qualcomm demos 3Gbit/s WiFI 6E at 6GHz

By Nick Flaherty

Qualcomm Technologies has demonstrated the next generation of WiFi operating at 6GHz, above today's current bands.

Despite the attempt to simplify the marketing names of WiFi generations with the move to WiFi6 away from the a,b,g,ad names, this next generation is being called WiFi 6E.

The demo at 6GHz uses Qualcomm's FastConnect mobile connectivity subsystem and Networking Pro Series Wi-Fi Access Point platforms. 

The new approach, which is still waiting for regulatory approval for the 6GHz band, supports numerous 160 MHz channels and advanced modulation techniques to boost the data rate to 3Gbit/s. Qualcomm likes it as this also gives the opportunity to add extra (non-standard) end-to-end Wi-Fi 6 features to differentiate its offerings.

“Building on our deep technology expertise and industry-proven feature superiority, Qualcomm Technologies is again poised to usher in a new era of Wi-Fi performance and capability with the addition of 6 GHz spectrum, or Wi-Fi 6E,” said Rahul Patel, senior vice president and general manager, connectivity and networking at Qualcomm Technologies. “Once the spectrum is allocated, Wi-Fi 6E is primed to solve for modern connectivity challenges and create new opportunities for the next generation of devices and experiences.”

Commercially available Wi-Fi 6 devices are now based on Qualcomm's Snapdragon 865 Mobile Platform. The latest FastConnect 6800 subsystem is capable of delivering a new class of Wi-Fi speed (approaching 1.8 Gbps) even in densely congested environments. This has support for uplink and downlink MU-MIMO (supporting up to 8 stream scenarios), OFDMA and 1024 QAM extended across 2.4 and 5GHz bands, and latency reducing optimizations. 

The Networking Pro Series provides networking processing and deterministic resource allocation through multi-user algorithms for OFDMA and MU-MIMO, and has been used in 200 designs shipping or in development.
