What is Li-Fi IEEE?
Light-Fidelity (LiFi) takes visible light communication (VLC) further by using light emitting diodes (LEDs) to realise fully networked wireless systems. Synergies are harnessed as lights become LiFi attocells resulting in enhanced wireless capacity for the Internet-of-Things (IoT), 5G and beyond.
Why do we need visible light communication?
The Li-Fi uses visible light for communication to provide high speed internet up to 10Gbits/s. Visible light is used to provide both lighting and information using VLC techniques. For example, we use lighting in the room to provide the room number identification and other information about the building.
How computer uses light as media of communication?
Answer: Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than electrical cables.
Why VLC is used in LiFi?
Visible light communication (VLC) is a wireless method that enables high-speed transmission of data with visible light. This data is transmitted by modulating the intensity of light given off by a light source.
What is LiFi paper?
Abstract: This paper attempts to clarify the difference between visible light communication (VLC) and light-fidelity (LiFi). In particular, it will show how LiFi takes VLC further by using light emitting diodes (LEDs) to realise fully networked wireless systems.
How is visible light used in daily life?
We often use visible light images to see clouds and to help predict the weather. We not only look at the Earth from space but we can also look at other planets from space. This is a visible light image of the planet Jupiter.
Is LiFi and visible light communication the same?
➤LiFi is the short form of Light Fidelity and VLC is the short form of Visible Light Communication. ➤VLC technology uses visible light part of the light spectrum where as LiFi technology uses any possible light spectrum for communication. ➤There are many applications of wireless communication viz.
Can visualvisible light communication be integrated with the Internet?
Visible Light Communication integrated with the Internet has already been studied by several works.
Is visible light communication the future of wireless communication?
Abstract: Visible light communication is a potentially disruptive form of wireless communication that can supplement radio frequency communication and also uniquely enable novel mobile wireless device use cases.
What is the IEEE 802 visible light communication standard?
To this end, in 2011, the IEEE 802.15.7 Visible Light Communication Task Group developed the first draft of the official IEEE 802.15.7 standard, in which the Physical and MAC layers for Short-Range Wireless Optical Communication Using Visible Light [12] are defined.
What is visible light communication channel?
Figure 15: Visible Light Communication channel and light propagation, adapted from. Users may move through an environment while using VLC applications. When the receiver’s device is a mobile device such as a smartphone, the user can constantly change direction and orientation.
