Wi-Fi 6 and Wi-Fi 6E feature prominently in the Wi-Fi design roadmap in 2022, followed by the Automated Frequency Coordination (AFC) system.
According to Wi-Fi Alliance, the number of Wi-Fi devices in use will reach nearly 18 billion in 2022. The network of companies that manages the Wi-Fi design ecosystem also predicts that 4.4 billion devices will be shipped. This year.
For the year 2022, Wi-Fi Alliance has listed four major trends described below.
- Wi-Fi an IoT building block
Wi-Fi, now widely recognized as a foundation technology for Internet of Things (IoT) applications, is solidifying its position with Wi-Fi 6 and Wi-Fi 6E, which use distribution multiple access frequency orthogonal (OFDMA) to improve performance in dense media. Then there’s Target Wake Time (TWT) technology, which reduces battery consumption and makes Wi-Fi a suitable choice for sensor-based devices.

Add to this the HaLow CERTIFIED Wi-Fi, which operates in the sub-1GHz band and enables long-range, low-power connectivity while providing a robust connection in harsh Wi-Fi environments. It facilitates a variety of energy-efficient IoT use cases in retail, agriculture, healthcare, smart home, and smart city environments.
- Wi-Fi 6 and Wi-Fi 6E in homes and businesses
According to the Wi-Fi Alliance, Wi-Fi 6 has achieved 50% market adoption faster than previous Wi-Fi generations. Wi-Fi 6 and Wi-Fi 6E are now being introduced for PCs, laptops and mesh systems, while home networking, automotive and augmented/virtual reality (AR/VR) applications are next in line. line.

The Wi-Fi Alliance also expects more Wi-Fi 6E access points to be deployed in home networks to meet the needs of bandwidth-intensive and latency-sensitive applications. Home gateways and Wi-Fi 6E access points are likely to be part of subscription plans offered by smart home and smart building service providers.
- Automatique frequency coordination (CIF)
AFC systems maximize spectrum access in the 6 GHz frequency band, and they have already been adopted in Canada and the United States. Wi-Fi Alliance released specifications and test plans for the implementation of the AFC system, and more than a dozen AFC service providers have expressed interest.

- Wi-Fi Network Optimization
The increasing use of video conferencing, voice over IP services, X Reality (XR) applications and high definition (HD) streaming in home and enterprise environments has placed new demands on Wi-Fi networks. inevitably requires a new level of network optimization.
Right here, Wi-Fi CERTIFIED Optimized Connectivity improves mobility when roaming within and across Wi-Fi networks and between Wi-Fi and cellular networks. Following, Wi-Fi CERTIFIED QoS management ensures robust service delivery and a high-quality Wi-Fi user experience. Then there is Wi-Fi Certified Data Elementsthat help service providers and network managers better manage complex Wi-Fi networks.
In 2022, Wi-Fi CERTIFIED hotspot will raise the bar for speed, security and reliability to better manage Wi-Fi deployments in dense, urban and public areas.
