Design of MIMO-FSO based IoT system

Free space optics (FSO) allows extensive transfer rate, low energy consumption and wide spectrum along with immunity against electromagnetic interference. This work reports a 10×10 Gbps multiple input multiple output FSO (MIMO-FSO) based internet of things (IoT) system under the impact of diverse climate conditions has been reported. The novelty of this work is to design an IoT based high speed as well as long reach wireless transmission system considering various environmental crises. The results show that FSO transmission range of 130 km for clear weather conditions. Also, the system using optimum value of transmission as well as reception aperture diameters means 10 and 40 cm respectively, FSO range can be considerably extended more than 110 km.
