The modern world heavily relies on wireless internet for various daily activities, including professional communication, internet browsing, and entertainment streaming. However, with the increasing demand for wireless internet access comes a greater power consumption that contributes to carbon emissions on a global scale. As a result, there is a growing need for future wireless networks to support the high computational demands of modern applications and internet services while also limiting power consumption.

In the quest for energy-efficient wireless communication solutions, researchers have been exploring various techniques to facilitate communication between devices and the sharing of information online. One of the innovative solutions that have emerged is visible light communication (VLC). This method utilizes visible light, often emitted by light-emitting diodes (LEDs) or other artificial light sources, to transmit data wirelessly.

A recent development in the field of wireless communication comes from researchers at Central University (CU), IIDM, and CU J&K in India. They have proposed a hybrid solution that combines VLC with RF communication to enable reliable communication in indoor environments with a high data transmission rate while consuming less energy. This hybrid system aims to decrease the carbon footprint in the atmosphere, make the network safer and more reliable, and provide communication along with illumination with lower power consumption.

The wireless communication system devised by the researchers consists of two main components: a transmitter and a receiver module. These modules are physically separate but connected via a VLC channel. The transmitter emits data stored in LED-produced light, while the receiver, equipped with a photosensitive device such as a photodiode or camera, extracts the information from the light emitted by the transmitter. Modulation schemes are used to maintain a continuous stream of data and keep the average power consumption constant throughout the communication process.

Simulation and Findings

To evaluate the performance of their proposed indoor wireless communication system, Kour, Jha, and Jain conducted simulations using various platforms such as Python, Scilab, and MathWorks tools. The results of their study indicate that the system enables stable communication between devices in the same indoor environment while achieving significant energy savings. Comparing RF communication, hybrid (RF+ VLC), and pure VLC, the researchers found that their hybrid approach exhibits high energy efficiency, lower Specific Absorption Rate (SAR), lower incident and absorbed power density, reduced complexity, and temperature elevation in human tissues exposed to radiation.

The study by Kour, Jha, and Jain contributes to the ongoing efforts to reduce power consumption and electromagnetic radiation in wireless communications. Their approach shows promise in enhancing energy efficiency, extending the battery life of mobile devices, and improving the overall quality of service and experience for users. The initial simulations conducted by the researchers provide a foundation for further studies and advancements in energy-efficient wireless communication technologies.
