ABSTRACT The spectrum is the rare coin for communication engineers. Nowadays, with the increasing rapid growth in wireless communications system the problem of using spectrum efficiently has become more important. There are many solutions have been proposed to solve this issue. The one of these solutions is the usage of visible light frequencies to send data. These frequencies are already free and unused. Light fidelity (Li-Fi) is a new short range optical wireless communication technology which provides the connectivity within a local network, by using Light-Emitting Diodes (LEDs) to transmit data depending on light illumination properties. Li-Fi represents Light Fidelity. Li-Fi is the future upcoming technology and this can transmit the information through light at high speed as compared to the present wireless technologies. The Li- Fi technology can transfer the data through LEDs. It is a high speed and low cost wireless communication system, compared to Wi-Fi. It can provide high security, large bandwidth. While using various color LEDs can get the different bandwidth and speed. We design and implement the Li-Fi data transmission system and analyzing its performance. Key words: OFDM, Wi-Fi, Light spectrum, LED, Photodiode
