During the last decade, the exponential growth of mobile devices and wireless services created an enormous demand for radio frequency-based technologies. Meanwhile, the industry has been revolutionized thanks to the popularization of Light Emitting Diode (LED) light bulbs, which are more economical and efficient. In this context, Visible Light Communication (VLC) may be a disruptive technology supported by LEDs that gives free spectrum and high rate, which may potentially function as a complementary technology to the current radio frequency standards. In the current scenario, there is a lot of increased usage of frequency (RF) for mobile communications. The paper reviews the VLC technology and replaces a small part of implementation of RF in communication usage.
Technology is growing rapidly and spreading its arm to every aspect of human life. With the growing technology, there are many other factors which are evolving and causing severe damage to the present form of nature, humans and wildlife (Raj, 2020). According to a study, an increase in CO2 equivalent emissions by a factor of three until 2020 compared to 2007, rising from about 86 to 235 M to CO2, suggests a steeper increase than predicted as per the well-known SMART2020 report (The Climate Group, 2020). Mobile devices and radio access networks that operate globally are the main contributors to the rising data traffic that corresponds to increased data capacity in each node of network either in form of wireless networking or wired networking, leading to emission of high amount of harmful radiation (from both radio and micro waves) to the surrounding nature. Improvements in technologies have a larger impact in making our lives easier, but on the other hand, it is also causing damage to the overall structure of the nature. A cell phone transmits 1 to 2 W of power in the frequency range of 824-849 MHz and 890-915 MHz (GSM1800). A cell phone has a particular Specific Absorption Rate (SAR) (Electromagentic Fields and Public Health, 2020). The number of cell phone users has increased rapidly (Raj, 2014). There were over 400 million cell phone subscribers in the United States in 2017 according to the Cellular Telecommunications and Internet Association (CTIA) (CITA, 2020). Globally, there are more than 5 billion cell phone users; from this, one can guess its impact on nature and human lives.
