This document discusses ITRI's research into visible light communication (VLC) technology for indoor positioning and communication applications. It provides the following key points: 1. ITRI has developed high-speed VLC transceivers capable of 100Mbps transmission over 3 meters that can enable integrated indoor communication and lighting. VLC provides benefits like high security, accurate indoor positioning under 1 meter, low cost, and no electromagnetic interference. 2. ITRI has conducted field trials of VLC indoor positioning systems in various settings like offices, hospitals, and exhibition rooms. These trials have demonstrated applications like location-based check-ins, automatic information downloading based on doctor position, and navigation within venues. 3. Compared to
