Abstract (300 words maximum)

Wi-Fi has been in existence since 1998 providing an increase in the amount of data transmitted and generated by machines. With the growing market demand for network bandwidth, it will make it nearly impossible for typical radio frequency (RF) technologies like Wi-Fi to supply the resources needed for the data transmission. As a complementary solution, Li-Fi was introduced in 2011 as a method of data transfer through the use light of light sources. Li-Fi employs the use of visible light spectrum which has 1000 more times the bandwidth of typical RF spectrums. This study investigates the distance to which this method of data transmission can be done on a simple LI-Fi transmission system. We use a basic LED to send signals to a photoresistor exploring the basis of using different lenses to further increase the distance of reception. In lab observations indicate that data transmission occurs after the light source was made to pass through different lenses. The result of this can be used as a starting point to determine how far a Li-Fi data packet can be sniffed without loss of packet information and increasing the distance of transmission.
