Abstract

In this Letter, we propose a novel indoor localization system based on optical wireless technology. By using the same architecture as the high-speed full-duplex indoor optical wireless communication system, the “search and scan” process, and the added transmission power and beam footprint information in the “search and scan” message, indoor localization functionality is achieved. Proof-of-concept experiments are carried out, and results show that an average error of <15cm is achieved with a localization beam size of 1 m. In addition, the major localization-accuracy-limiting factors are analyzed both theoretically and experimentally. When incorporated with the optical wireless communication system, high-speed indoor wireless personal area networks can be achieved.
