Comparison of LIFI and WIFI and study of smart meter-survey

Li-Fi stands for Light-Fidelity. Li-Fi innovation, which was suggested by Harald Haas, a German physicist, gives conduction of information over brightening through distribution of information via a LED light which changes in force quicker when compared to the vision of human beings which could take after. Wi-Fi is extraordinary for overall remote scope inside structures, while Li-Fi has been perfect for high thickness remote information scope in limited range besides for calming wireless impedance concerns. Smart meters are electronic devices which are used for recording consumption of electrical energy on a regular basis at an interval of an hour or less. In this paper, we motivate the need to learn and understand about the various new technologies like LiFi and its advantages. Further, we will understand the comparison between LiFi and Wi-Fi and learn about the advantages of using LiFi over WiFi. In addition to that we will also learn about the working of smart meters and its communication of the recorded information on a daily basis to the utility for monitoring and billing purposes.
