Abstract: Within 10 m WLAN and within 10 cm from the two-way data communication possible close contact/contactless data communications technology is applied very widely spread. In this study, the visible light wavelength using optical wireless communication technology in ultra wideband characteristics of LED-VLC systems technology trends, seems to have promise, Li-Fi technology characteristics and indoor navigation/ITS/cultural content delivery/u-home construction, etc. Li-Fi a wide variety of applications in the system such as building, posed an obstacle between the chip and smart appliances the beacon light wave transmission characteristics of problems/strong external light due to the communication failure is due to a century of telecommunications/light such as the limits of the problem to be solved due to the improving the performance of high-value industries, LED by noted LED-VLC and standardizes the marketability of technology about the prospect. Wi-Fi >100 times over high-speed bidirectional wireless transmission system, possible Li-Fi network powered by the next generation of growth emerging. Li-Fi technology Wi-Fi high efficiency lighting technology and internet shares LED the technology combines LED-VLC technology. LED lighting technology-based Li-Fi system for indoor navigation, ITS, content delivery and u-home construction was the application in a variety of industries are going to spread those values. Indoor navigation GPS systems that are difficult to operate in the field of Interior of barriers will be able to solve. Li-Fi technology is applied very widely spread that WLAN (10 cm~10 m) from the two-way data communication possible close contact/contactless.
