Continuing the discussion from Status of WiFi 6E and 6GHz spectrum?:
WiFi 7 devices can now receive certification from the ‘Wi-Fi Alliance’. Taiwan just recently started allowing WiFi 6E devices to be operated in Taiwan. I hope this time it will be a faster process, so we can use the new technology in Taiwan soon. @au

Advanced features include:
- 320 MHz channels: available in countries that make the 6 GHz band available to
Wi-Fi, ultra-wide channels double today’s widest channel size to facilitate multigigabit device speeds and high throughput - Multi-Link Operation (MLO): allows devices to transmit and receive data simultaneously over multiple links for increased throughput, reduced latency, and improved reliability
- 4K QAM: achieves 20% higher transmission rates than 1024 QAM
- 512 Compressed block-ack: improves efficiency and reduces overhead
- Multiple RUs to a single STA: improves flexibility for spectrum resource scheduling to enhance spectrum efficiency
- Triggered Uplink Access: optimizes Wi-Fi 6 defined triggered uplink access to accommodate latency sensitive streams and satisfy QoS requirements
- Emergency Preparedness Communication Services (EPCS): provides a seamless National Security & Emergency Preparedness (NSEP) service experience to users while maintaining the priority and quality of service in Wi-Fi access networks
