If you’re curious as to how your organization could benefit from li-fi, we’ve rounded up a few of the technology’s most unique features. This page covers advantages and disadvantages of mentions LiFi This technology is based on visible light communication (VLC). • Operating range. ADVANTAGES Enhanced wireless infrastructures by providing an additional layer of small cells. The avoidance of the radio frequency.

Li-Fi stands for Light Fidelity and it is a technology that aims to provide faster and more secure data transfer applications using LED lights. High installation cost of the VLC advzntages. Li-Fi data is transmitted by the LED bulbs and received by photoreceptors in receiving device.

Sunlight will interfere the signals, resulting in interrupted Internet. A lot of free radio spectrum will be available as Li-Fi can be used to free some busy spectrums in a confined area. Any private or public lighting including street lamps can be used to provide Li-Fi hotspots and the same communications and sensor infrastructure can be used to monitor and control lighting and data.

This could limit the locations and situations in which Li-Fi could be used. This may not necessarily be a disadvantage because Li-Fi would be very useful in situations in which information needs to be disseminated locally for specific uses, perhaps to provide lecture attendees with notes, pictures, and digitized handouts, eliminating the need for troublesome and poorly visible blackboards.

This will avoid unwanted access of lifi signal by unauthorized persons. How does it work? The data in light form is then transmitted through the LED light bulb. That is, the light can belong to the invisible, ultraviolet or the visible part of the spectrum as well.


Interferences from external light sources like sun, light, normal bulbs, opaque materials. Unbounded media have network signals that are not bound by any type of fiber or cable; hence, they are also called wireless technologies Diasdvantages LAN. Making Sense of the Wi-Fi is great for general wireless coverage within building whereas Li-Fi advntages ideal for high density wireless date coverage in confined area and for relieving radio interference issues.

With more big data solutions moving to the cloud, how will that impact network performance and security? Other sources of light may interfere with the signal. In Octobercompanies and industry groups formed the Li-Fi Consortium, to disadvantayes high-speed optical wireless systems. What to Expect in More From Our Experts. Since light cannot pass through opaque structures, Li-Fi Internet is available only to the users advabtages a room and cannot be breached by users in other rooms or buildings.


Share buttons are a little bit lower. What is the difference between Bluetooth and Wi-Fi? Feedback Privacy Policy Feedback. Li-Fi uses LED light bulbs with just a few changes that enable them to transfer data on certain frequencies. Infrared Infrared data travels in shorter near infrared waves. The technology uses LED lamps on source side and photo detector axvantages LiFi dongles on destination side.

Each of these communications technologies offers its own advantages depending on the circumstances. Keyboard connected to the computer, as well as technoloyg printer, mouse, monitor and so on. Thus, the range of frequencies available to transmit Li-Fi data is virtually limitless.


If you liti to download it, please recommend it to your friends in any social system. Li-Fi, which uses visible light to transmit signals wirelessly, is an emerging technology poised to compete with Wi-Fi.

Wireless networking technologies allow devices to communicate. One main advantage of Li-Fi is security.

Leave your thoughts in the comments section below. Laptops, smart phones, tablets and other mobile devices can interconnect directly using Li- Fi. Since disacvantages cannot penetrate walls, it provides privacy and security that Wi-Fi cannot.

Wherever there is a light source, there can be Internet. Instead of Wi-Fi modems, Li-Fi will use transceiver-fitted LED lamps that can light a room as well as transmit and receive information. These waves enable data to be sent and receive.

Li-Fi & All about it Light Fidelity & How it will change the way we perform data transfers!!

My presentations Profile Feedback Log out. Typical transmission capacities for both services are in the order of 1 Gbit per second, but both Wi-Fi and Li-Fi have the inherent capacity for much higher rates. How is it different from other technologies?
