Four Important Wi-Fi Design Trends to Watch in 2022

Article by: Majeed Ahmad

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.

  1. 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.

  1. 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.

  1. 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.

  1. 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.
