The Next Generation of Wireless Communication Using Li-Fi (Light Fidelity) Technology

Abstract

Today scenario almost all the peoples are using internet to fulfill their task through a wired or wireless network. The speed of internet is an important issue and everyone be it business, organizations, entrepreneurs, and institutions is thrust for getting correct information at the correct time and correct place. Then need rapid internet connectivity, technology and huge spectrum of channels. The wireless-fidelity (Wi-Fi) gives you the speed of 150 Mbps, according to standards of 1EEE 802.11n, but not sufficient to fulfill the necessity of required users over the network. In order to remove this deficiency of Wi-Fi, a new technology is developed by German physicist, professor Harald Haas is known as Li-Fi. The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi. Li-Fi is a technology that utilizes a light emitting diode to transmit data wirelessly. It uses a bidirectional and the wireless mode of communication using light. In this paper, I am aiming to demonstrate a close-up view about Li-Fi Technology. This technology we can obtain the data rate greatly speedier than 10 Mbps, which is a lot greater than our LAN (Local Area Network). Li-Fi is very remunerative over Wi-Fi as it uses VLC by which we can make use of the maximum 60 GHz spectrum. Li-Fi confer transmission of data via LED bulb whose intensity change in an excessively faster speed that it could not be able to be explored by the human eye. Li-Fi is confined to the illuminated area, endue a tremendously controllable environment. The signals cannot travel via walls and are fully secure essentially disassemble the threat of data being hacked remotely.

Design and Implementation of V2V and V2I Communication Systems using ML based Li-Fi technology

“…A scientist from German Herald Hass developed transfer of data by use of light-weight delity. the invention are going to be replaced for Wi-Fi, the knowledge transferred at vary 500Mbps [7]. This instrumentation practices every kind of spectrum same as white light-weight, infrared.…”

An Extended Review on Internet of Things (IoT) and its Promising Applications

“…Pay attention that many of IoT technologies are actually utilized in WSNs or machine to machine (M2M) communications but were ameliorate to meet IoT requirements. The several modern devices use more than one technology; as in smart watches, which often have Wi-Fi, Bluetooth, Li-Fi, and NFC [21] [22]. In this section, we classify the enabling technologies based on their functionality in the network layer.…”

“…The most general communication technologies for short range, low power communication protocols are NFC (Near Field Communication) and RFID (Radio Frequency Identification) [32]. For the medium range, they are Bluetooth [21], Zigbee, and WiFi, Li Fi [22]. Communication in the IoT world needed special networking protocols and mechanisms.…”

Novel Design for Li-Fi Healthcare Monitoring System

“…The FBGs are categorized into three main classifications based on photosensitivity, structures, and refractive index [17]. FBGs can be effectively utilized in an extensive variety of biomedical applications such as blood pressure, temperature and tumour detection [18].…”
