An Approach to Enhancing Industrial Safety via M2M Communication Utilizing Effulgence

While radio frequency is commonly employed for communication purposes, Visible Light Communication (VLC) presents several advantages over the invisible radio frequencies. VLC boasts minimal latency and high bandwidth, in contrast to radio, which operates within a more restricted spectrum and is more susceptible to issues like cross talk and interference when compared to VLC. The requirement for a direct line of sight can also be viewed as a security feature, except in cases where a hacker has a clear line of sight to a network device on a private network, leaving it vulnerable to external air gap attacks. Li-Fi, an implementation of wireless networking, utilizes VLC technology. While Visible Light Communication (VLC) technologies were historically less prevalent, the allure of light-based communication is on the rise due to the increasing proliferation of wireless devices and the escalating congestion of the radio spectrum. The growing interest in VLC technologies stems from their distinctive capability to function without causing interference, even in scenarios where multiple networks employing different radio frequencies coexist. VLC technology is being leveraged as a cost-effective means of connecting millions of consumer electronics and machine-to-machine (M2M) devices. This paper aims to clarify the utilization of the visible light spectrum for data communication, with particular emphasis on how Li-Fi enhances Visible Light Communication (VLC) by utilizing light-emitting diodes (LEDs) to establish a fully networked wireless system. Li-Fi represents a promising addition to efficient wireless data transmission systems, thanks to its exceptional speed capabilities, suggesting significant potential for future applications. By harnessing the concept of Li-Fi, we are currently implementing a module that enables the control of a buggy based on commands transmitted via LED light.
