transmits this incoming signal to the CPU through a serial port. The CPU assumes control over the smart home appliances in line with the smartphone-initiated incoming instructions. From all indications, Wi-Fi remains an essential element of the overall process of the smart home system. Figure 1 presents the structure of an example of a Wi-Fi- connected smart home system. The primary role of the CPU includes communicating with the host computer to collect and analyse real-time instructions from the smartphone and use such instructions to carry out relevant operations. In addition to providing power for the Wi-Fi 6 wireless module, the CPU also ensures effective communication with the module
through the serial port. Depending on the designer’s chosen Wi-Fi module within the smart home system, users may enjoy high- frequency applications with a high likelihood of extending to 5G dual- band and LTE (Long Term Evolution) data module applications, which can dramatically improve the performance and memory, as well as radiofrequency optimisations. Technical details of Wi-Fi 6 Unlike Wi-Fi 5 and older versions of the technology, Wi-Fi 6 exhibits several improvements to wireless connectivity, making it ideal for the increasingly demanding requirements of smart home applications. This section explores several technical specifications of the Wi-Fi 6 technology.
QAM, OBSS management, and beamforming for improved quality of service Wi-Fi 6 offers a dense QAM (quadrature amplitude modulation) of up to 1,024, which translates to improved throughput and enhanced capacity for various applications in both smart homes and smart buildings. This capability allows the encoding of more data bits and offers the Wi-Fi 6 wireless access point a 25% increase in data when compared to Wi-Fi 5. The 1,024 QAM specification of Wi-Fi 6 enables the technology to offer improved quality of service (or QoS) in densely populated locations, such as stadiums, convention centres, transportation hubs, and auditoriums.
