Abstract
This research study demonstrates the viability of adopting the planned IEEE 802.15.7 standard as a foundation for the creation of low-to-medium data rate VLC applications in the commercial sector. The proof-of-concept shown here combines software and hardware pieces to provide a versatile platform where new features may be introduced without much programming. It can be concluded that a VLC system's dual functionality requirement is readily met by adhering to the IEEE 802.15.7 standard standards. Using a commercial or specialty lighting microcontroller, the software define part of the approach provided here may be adapted to meet the low cost criterion imposed on commercial VLC LED luminaries. Many examples of greater data rate transmission by utilizing other modulation methods may be found in the VLC literature, but our system's goal was to showcase the potential of a VLC system that adheres to industry standards. The provided solution demonstrates that the IEEE 802.15.7 standard has reached a level of maturity where cost-effective, simple, and performant solutions may be deployed utilizing commercial off-the-shelf (COTS) devices for the aforementioned use cases. In order to improve the user experience and aid in the growth of the smart cities idea, VLC systems should not be considered as a replacement for Wi-Fi or any other wireless radio system.
