Implementation of Li-Fi Technology in Smart Home Systems: Development and Analysis of a Prototype for Enhanced Wireless Communication

Exploring innovative communication technologies has been a pressing need due to the need for reliable and efficient data transmission in networks such as industrial automation, IoT devices, and healthcare systems. This research investigates a wireless communication system that uses visible light, called microcontrollers, with Li-Fi technology instead of radio waves to enhance data accuracy and resilience. Unlike traditional legacy systems, Li-Fi technology provides a buffer against electromagnetic interference, making it a promising alternative for smart home automation. This research includes a developed prototype that uses visible light communication (VLC) through LEDs and an LDR receiver, controlled by an Arduino microcontroller. The KNX standard was adopted in building the proposed system, which has been widely adopted in building automation. The results showed that the Li-Fi-based system improves the accuracy of data transmission as well as the data transmission power. This research, along with other researches on Li-Fi, contributes by demonstrating its applicability in smart home environments, and thus this technology will revolutionize wireless communications across various fields.
