Arif’s comparative Analysis of Li-Fi over Wi-Fi

Abstract Li-Fi stands for Light Fidelity. Li-Fi is a wireless optical networking technology that uses light emitting diodes LEDs for transmission of data. The IEEE This paper focuses on Li-Fi, its applications, features and comparison with existing technologies like Wi-Fi etc. Wi-Fi is of major use for general wireless coverage within building, whereas Li-Fi is ideal for high density wireless data coverage in confined area and especially useful for applications in areas where radio interference issues are of concern, so the two technologies can be considered complimentary. Li-Fi provides better bandwidth, efficiency, connectivity and security than Wi-Fi and has already achieved high speeds larger than 1 Gbps under the laboratory conditions. By Leveraging the low-cost nature of LEDs and lighting units, there are lots of opportunities to exploit this medium.

It is the transmission of information utilizing light waves by fluctuating the intensity of the light speedier than human observation that follows VLC technology. VLC utilizes quick beats of light to transmit data remotely. It uses LEDs is rising as a key innovation for a universal correspondence framework, since LED has the benefits of quick exchanging, long future, being less costly and being obvious light that is secure for the human body. LEDs are unique in relation with different lights since they are semiconductors. For such qualities, it gives them the capacity to switch-off and on inside couple of nanoseconds. So, the demonstrations here are quite conceptual that simply transmit information in parallel utilizing VLC innovation. There are some advantages of Li-Fi over Wi-Fi and has much more scope and possibilities to research on.

Li-Fi also written as LiFi is a wireless communication technology which utilizes light to transmit data and position between devices. In technical terms, Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light , ultraviolet , and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light. In terms of its end use , the technology is similar to Wi-Fi — the key technical difference being that Wi-Fi uses radio frequency to induce a voltage in an antenna to transmit data, whereas Li-Fi uses the modulation of light intensity to transmit data. Li-Fi's ability to safely function in areas otherwise susceptible to electromagnetic interference e. 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-speed communication in a similar manner to Wi-Fi. Visible light communications VLC works by switching the current to the LEDs off and on at a very high speed, [6] too quick to be noticed by the human eye, thus, it does not present any flickering.

We apologize for the inconvenience...

It seems that Wi-Fi technology offers high data rate, about Mbps, comparing with others current wireless technologies. It is a form of visible light communication technology that is capable of transmitting data in two directions. LiFi is a wireless optical networking technology.

Both Bluetooth and Wi-Fi are used for providing wireless communication through radio signals. The most distinction between Bluetooth and Wifi is that, Bluetooth is actually accustomed connect short-range devices for sharing information whereas Wifi is used for providing high-speed web access or internet.

Немедленно. Это приказ. Чатрукьян замер от неожиданности.

Как это удобно. Вспомнив всю услышанную от шефа ложь, она похолодела и посмотрела на него, в глазах ее мелькнуло подозрение. - Это вы убили Танкадо.

Она постучала пальцем по кипе документов: - Вот твоя жизнь, Чед Бринкерхофф.  - Но, посмотрев на него, смягчилась.  - Могу я чем-нибудь тебе помочь, прежде чем уйду. Он посмотрел на нее умоляюще и покрутил затекшей шеей.

Сьюзан понимала, что, по всей логике, именно ей предстояло решить эту задачу. Она вздохнула, надеясь, что ей не придется раскаиваться в том, чем она собиралась заняться. - Если все пойдет хорошо, то результат будет примерно через полчаса.

Только его собственные утверждения в электронных посланиях. И конечно… ТРАНСТЕКСТ. Компьютер висел уже почти двадцать часов.
