Abstract: Nowadays people prefer wireless network to wired network, though the network speed is not constant they use wireless network because they provides us many benefits like portability and flexibility. We have Wi-Fi hotspots at home, coffee shops, airports, hotels and even cities. Due to this, Radio spectrum is getting clogged day by day and demand for wireless network is increasing drastically every year. An emerging technology using Visible Light Communications (VLC) for high speed wireless communications is Light Fidelity commonly known as Li-Fi. Li-Fi uses light as a carrier signal instead of radio frequency as in Wi-Fi. Li-Fi is a technology that uses LED's to transmit data without wire. LED is the key component in this data transmission as LED has the capacity of fast switching ON and OFF. The major problem faced in Li-Fi technology is, if the receiver or the photo detector is inclined at some angle then it doesn’t have the capacity to receive the particular light signal that consist of the data that is being transmitted by the Li-Fi LED bulbs. The main objective of this paper is to implement the absorption concept i.e. using high sensitive photo detector when it is inclined to some angle it must start absorbing the light that is being transmitted by the LED bulb.
