    Short range communication using visible light
    (University of Management and Technolog, 2017) Mian Zeeshan Akbar; Zubair Ali Khan; Muhammad Saleem
    Goals of this project are to study and optimize short range communication using visible light for increased data rates and less noise. Using light instead of conventional means of communication can help in reduce problems relating healthcare. Using LED instead of SONAR can help reduce threat to marine life, while increasing data transfer rate and minimizing noise caused by water for conventional communication instruments. This thesis will give information and follow through of a system which will allow electromagnetic radio signal to be converted into modulated light signal with frequency shifting modulation and transmitting it with the help of crystal LED. Modulated optical signal can then be transmitted into a photo diode to demodulate received signal back into electromagnetic signal. It can replace all conventional means of communication in future if more LEDs of high intensity are manufactured.
