Studies on Li-Fi (Light Fidelity)-The technology In wireless communication

Abstract

Internet usage and the need for data transfer are in high demand. Compared to earlier decades, people are more reliant on the internet. Spectrum is thus getting congested due to the rise of customers. Wi-Fi technology, which operates on radio frequency waves with limited bandwidth and is currently widely used, has been replaced by Li-Fi, which has a wider bandwidth and a higher data transfer rate. Recent studies indicate that Li-Fi has a range of about 10 meters. Additionally, it is unable to pass through walls or other solid objects. Therefore, the primary goal of this research is to extend the 10-meter range. This range is sufficient for an average-sized room. However, this range is insufficient if someone wants to give data within a long hallway or in any other large room. He needs to supply extra LEDs that are wired to the Li-Fi router. The goal of this research is to maximize LED usage while lowering costs. Here, two strategies to extend LED's range are suggested. One technique involves the placement of the LEDs, while another involves the use of a concave mirror. Better light coverage is produced by clever light positioning, which extends the LED's range. For a specific positioning of an item, a concave mirror provides a genuine and enhanced mirror, which is demonstrated both theoretically and mathematically.
