Transmission of Audio, Voice and Text using Visible Light Communication

Abstract

In recent technology Visible Light Communication (VLC) is utilizes visible light to transmit the data. While it's commonly used for indoor lighting, it can also be harnessed to transmit audio, text, and even voice signals. it's worth noting that VLC faces some challenges compared to traditional wireless communication technologies. For instance, VLC requires a direct line of sight between the transmitter and receiver, making it less suitable for long-range communication or scenarios with obstacles obstructing the light path, because it has few advantages over other standard wireless transmissions. The advantages of VLC are low power consumption, high data rate, more security and can avoid interference occurs. Under various constraints, including light intensity, output quality, and distance, the transmitter and receiver system will combine the audio, text, and speech transmission utilizing Li-Fi and validate its performance. Li-Fi employs standard light for transmissions at 10 Kbit/s or LED for up to 500 Mbit/s of connectivity over short distances. This paper describes a system that can provide data over a range of distances through experimentation. We are also implementing the transmission of Audio, Voice and Text Using Visible Light Communication for indoor location-based services.
