Abstract
In the world of communication, the wireless data communication moves to the driver seat. Light Fidelity (Li-Fi) technology becoming as one of the choice in the short distance wireless data communication system. Huge amount of data transmission is taking place through the electromagnetic spectrum. Cisco Visual Networking Index (VNI) reports a sharp traffic of the data has an increase of 69% during 2014 compared to the previous year 2013. More than 80% of mobile data traffic occurs in close door environment and the radio frequency spectrum is the medium for data transmission. Presently, Wi-Fi technology is used extensively for the wireless data communication. The performance of Wi-Fi system is affected by spectrum related issues such as capacity, efficiency, availability and security. The electromagnetic spectrum issue is important problem in the Wi-Fi technology.
The third and fourth Generation technologies consume large section of the electromagnetic spectrum. The volume of the uses affects the performance and efficiency of the Wi-Fi technology. Electromagnetic spectrum consists ...
