Wi-Fi 6 is the name given to the IEEE (Institute of Electrical and Electronics Engineers) standard known as 802.11ax, and it follows Wi- Fi 5 (IEEE 802.11ac). Due largely to its hardware offering much higher efficiency than its preceding iterations, Wi-Fi 6 is equipped to benefit and optimise smart homes in ways that can only be achieved with the 802.11ax standard.
This discussion considers both the technical specifications and benefits of Wi-Fi 6 in the context of smart homes. Wi-Fi 6 hardware To consider the principles of Wi-Fi 6 in smart homes, it is necessary to explore the overall design of a Wi- Fi-connected smart home system. The Institute of Physics-published journal ‘The Application of Wifi Technology in Smart Home’ [1] identifies the key elements of a Wi- Fi connected smart home system: ■ A central processing unit (CPU) ■ A smartphone that serves as a
carrier control terminal ■ An intelligent control system ■ The Wi-Fi module The intelligent control system comprises an audio-visual equipment control system, home lighting intelligent control system, home appliances intelligent control system, and an Android smartphone system, which work together to ensure the proper functioning of the smart home. The intelligent control system sends control commands to the CPU using a Wi-Fi 6 network. After receiving the command, the CPU parses it to perform several functions in the smart home,
including setting the air conditioner, switching on and off lights, controlling doors and windows, and so on. In addition, users can utilise the Wi-Fi-connected smartphone to gain access to the real-time data provided by the CPU about the smart home system. Designers incorporate a CPU, Wi-Fi 6 module, and a control terminal into the smart home design. The control terminal, which includes the smartphone, transmits information to the Wi-Fi 6 module connected to a similar network through Wi-Fi 6. The module then
