Visible light communication (VLC) exhibits great potential in connecting Internet of Things (IoT) devices. The connection of a huge number of IoT devices by utilizing the existing radio-frequency spectrum is a challenging task. Therefore, a new frequency spectrum is required for a smooth operation. In this work, we investigate a multiple-input multiple-output (MIMO) VLC system capable of connecting IoT devices to achieve long-range indoor communication. To monitor the indoor environment, a monitoring system for collecting and transmitting particulate matter, temperature, and humidity data using MIMO VLC is proposed. Four different single-carrier techniques are tested, and their error performance is analyzed by experimental trials. Next, the maximum communication range, which is important for efficient network planning and uninterrupted connectivity, is evaluated. Two antenna configurations (2 2 and 4 4) are …
