Over the past 20 years Wi-Fi has evolved from 2 Mbps to gigabit speeds, a 1000-fold increase in throughput. The standard has advanced through the introduction of new technologies with Wi-Fi 4, Wi-Fi 5 and, most recently, Wi-Fi%nbsp;6 and 6E. During this evolution, the Wi-Fi Alliance has maintained impressive backwards compatibility so products can work with a wide variety of routers installed in homes and offices, as well as in industry. This has been a key driver for the stability and growth of Wi-Fi as the cornerstone of the Internet of Things (IoT).
As the standards evolve, the process of choosing the right Wi-Fi version for IoT products continues to require careful consideration. While adding Wi-Fi 6 to a smartphone may be an easy decision, the considerations in IoT products are often different, with an intense focus on reliability, range/congestion, adoption of the new standard in Wi-Fi routers, cost, security, and power consumption. As a product manager, the decision of which version of Wi-Fi to use needs to be taken for each new product under your control. When should Wi-Fi 4, 5, or 6 be used? When is the right time to update products? The following online resource will provide links that will answer these and other questions: https://www.infineon.com/cms/en/product/promopages/wi-fi-6/
