Audio Transmission Through Li-Fi Using Nodemcu

Abstract

In today's interconnected world, the proliferation of wireless devices accessing the internet continues to surge, leading to escalating network complexity and a strain on available wireless radio bandwidth. This surge also raises concerns about the potential for interference in radio frequencies, which can compromise the reliability and security of data transmission. However, Li-Fi technology offers a promising solution by using light-emitting diodes for data transmission. Li-Fi operates by using LEDs as transmitters and photodiodes as receivers, utilizing light waves to carry data instead of traditional radio frequencies. The use of light for data transmission not only enhances security but also mitigates concerns about radio frequency interference. Moreover, the rapid advancements in LED manufacturing have led to the development of highly efficient, durable, and long-lasting LEDs, making them suitable for both private lighting and data transmission purposes. The effectiveness of Li-Fi is further underscored by its ability to achieve data transmission rates of several gigabits per second (GBPS), surpassing many existing wireless technologies. Consequently, the implementation of Li-Fi technology holds immense potential for revolutionizing communication systems, particularly in environments where security, speed, and reliability are paramount. The design and implementation of Li-Fi audio transmission systems exemplify the innovative applications of this cutting-edge technology, offering a glimpse into the future of wireless communication. As research and development in Li-Fi continues to progress, the possibilities for its integration into various industries and everyday applications are limitless, paving the way for a more efficient and interconnected world.
