MUSEUM: display presentations, transforms smartphones or tablets to visitor guides. There is also an additional cost benefit as installing new radio base stations usually comes with large cost – for installation and site lease. It is a subset of optical wireless communication technologies. This would enable car systems to download information from the network and have real time information on optimal routes to take, and update the network regarding conditions recently experienced by individual vehicles. As mentioned earlier, the LiFi technology capitalizes the minutest fluctuations in LED lights to transmit data from the transmitter to the receiver. Radio frequency technology such as Wi-Fi is vulnerable to interference from a wide range of devices such as cordless phones, microwaves and neighbouring Wi-Fi networks. Li-Fi is a derivative of optical wireless communications (OWC) technology, which uses light from light-emitting diodes (LEDs) as a medium to deliver network, mobile, high … LiFi applications are varied as a result of its key features, such as directional lighting, energy efficiency, intrinsic security, high data rate capability, signal blocking by walls and integrated networking capability. It will allow connectivity at all times, without creating electromagnetic interference (EMI) with sensitive radio equipment on the flight deck. Each light fixture in the application environment becomes a separate data channel. Museum. guide for street shopping, tourist area, community information. for bus schedules, information and traffic news …. LiFi is a wireless data communication technology using LEDs to transmit data via light. Li-Fi has shown that it's 100 times faster than Wi-Fi. Since the beginnings of the Internet, connections have not stopped improving, driven by ever-incre… Car headlights and tail lights are steadily being replaced with LED versions. The technology can unlock the potential of IoT, drive Industry 4.0 applications, and lead to the upcoming of light-as-a-service (LaaS) in the lighting industry. The basic ideology of this technology is transference of data using LED light of varying intensities. Because of these advantages the LI-FI technology is going to hit an upper level. The reduction in cabling requirement also means a lighter aircraft. LiFi signals can be defined by the area of illumination, which means interference is much simpler to avoid and even stop altogether. Our homes already have lighting widely installed. G1 1RD. In October 2011, companies and industry groups formed the Li-Fi consortium, to promote high-speed optical wireless system and to overcome the limited amount of radio-based wireless spectrum available by exploiting a completely different part of the electrom agnetic spectrum. Therefore, with minimal precautions to avoid leakage from windows, etc., security is fundamentally enhanced as compared with Wi-Fi. Catalogue information, discount coupons, and advertising videos could all be provided to shoppers. Applications of Lifi The applications of Li-Fi are limitless. In its commercial application, LiFi will challenge WiFi’s dominance of the networkable wireless field. In other words, street lamps would provide both; data communication and lighting. Nowadays, the most trending domain in wireless communication is Wi-Fi and internet users are also being increased every year. This report presents an analysis of LiFi technology and applications, including: basic principles, specifications, positioning of LiFi with other OWC technologies, benefits and challenges, and classification of applications with use-cases. Traffic lights already use LED lighting, so that there is also the prospect offered of city wide traffic management systems. PureLiFi and Philips are the notable names in research of Li-Fi technology. Oledcomm used a Li-Fi-enabled lightbulb to transmit data at speeds as fast as 1 gigabits per second (Gbps). So, instead of deploying new radio base stations in our cities, street lamps could provide both, illumination during night, and high speed data communication 24/7. With Li-Fi, your light blub is essentially your router. Exhibits in museums and galleries are illuminated with specific lighting. The term Li-Fi is similar to Wi-Fi excluding the fact that light rather than radio technology is used for data transmission. Visible light communication (VLC) is a data communication method that uses visible light between 400THz and 800THz (Tera-Hertz) frequency; wavelength is 780nm to 375nm. can find or promote products in the aisles, guide the customer to the desired items, etc. LiFi Research and Development Centre, Li-Fi-light fidelity is similar to Wi-Fi technology and it is one of the future wireless communication technologies.
