The Wi-Fi Alliance today announced the availability of Wi-Fi Certified 7, which aims to ensure interoperability among Wi-Fi 7 devices. Wi-Fi 7 devices, already on the market, support a range of new features such as higher throughput, deterministic latency and greater reliability for critical traffic.
Those capability are expected to support new use cases including including multi-user AR/VR/XR, immersive 3-D training, electronic gaming, hybrid work, industrial IoT and automotive. The Wi-Fi Alliance expects more than 233 million Wi-Fi 7 devices to enter the market in 2024, growing to 2.1 billion devices by 2028.
Vendors that have Wi-Fi Certified 7 devices include Broadcom, CommScope, Intel, MaxLinear, MediaTek and Qualcomm.
Advanced features of the technology include:
- Multi-link operation (MLO), which enables devices to transmit and receive data simultaneously over multiple links. This increases throughput, reduces latency and improves reliability.
- 4K QAM, which achieves 20% faster transmission rates than 1024 QAM
- 512 Compressed block-ack, which improves efficiency while reducing overhead
- 320 MHz channels, which are available in those countries where the 6 GHz band is available for Wi-Fi. The ultra-wide channels double the widest channel size to facilitate multigigabit device speeds and high throughput
- Multiple RUs to a single STA, which is designed to improve flexibility for spectrum resource scheduling to enhance spectrum efficiency
- Triggered uplink access, which is designed to optimize Wi-Fi 6 defined triggered uplink access to accommodate latency sensitive streams and satisfy QoS requirements
- Emergency Preparedness Communication Services (EPCS), which is designed to provide seamless National Security & Emergency Preparedness (NSEP) service for users while also maintaining the priority and quality of service in Wi-Fi access networks
“The introduction of Wi-Fi Certified 7 marks the emergence of the latest generation in the evolution of wireless connectivity,” Kevin Robinson, president and CEO, Wi-Fi Alliance, said in a prepared statement. “This certification underscores our relentless commitment to delivering cutting-edge technology that redefines the way users experience Wi-Fi, providing faster speeds, improved efficiency, and increased reliability which expand the horizons of what is possible through Wi-Fi.”
