Abstract

Point to multipoint link has been proposed using 650nm LASER over a Free Space Optics Technology. A comparative analysis of Power Vs distance has been carried over free space optics link. Prototype model send the data to other users wirelessly. Prototype model is designed in such a way that it transmits the data through light instead of using any Radio Frequency signal. Light from a LASER torch transmit up to the distance of 43metres with the lesser power of 5mw. Using 650nm LASER, power of system has been analyzed.
