Wi-Fi Alliance launches the Wi-Fi 7 advanced wireless standard certification

The Wi-Fi Alliance has announced the completion and launch of the Wi-Fi 7 advanced wireless standard certification, poised to enhance connectivity performance for devices in homes, offices, and industrial settings, while also introducing a new certification logo. The Wi-Fi Alliance states that the introduction of Wi-Fi 7 certification is designed to uphold the standards of upcoming wireless devices. Although it might take some time, there are already numerous systems, mobile devices, and routers on the market that comply with the Wi-Fi 7 standards.

To qualify for the Wi-Fi 7 certification, devices must utilize the following feature set:

• 320MHz Channels – Provided in countries/regions where the 6GHz band is permitted for Wi-Fi use.
• Multi-Link Operation (MLO) – Enables devices to simultaneously transmit and receive data across multiple links, thereby enhancing throughput, reducing latency, and increasing reliability.
• 4K QAM – Offers a data transmission rate that is 20% higher than the 1024-QAM of Wi-Fi 6E.
• 512 Compressed Block-Ack – Boosts efficiency and minimizes transmission consumption.
• Multi-RU Mechanism – Allows the allocation of multiple RUs to a single user, enhancing the flexibility of frequency band resource scheduling.
• Trigger-Based Uplink Access – Optimizes the trigger-based uplink access defined by Wi-Fi 6 to accommodate latency-sensitive data streams and meet QoS requirements.
• EPCS – Provides users with a seamless experience of security and emergency preparedness services, while maintaining the priority and quality of service of Wi-Fi access networks.
