8 FAQ About LiFi Technology:

What is LiFi?

LiFi, also known as “Light Fidelity,” is a wireless optical networking technology that uses light-emitting diodes (LEDs) to transmit data. This technology was first demonstrated in 2011 by Professor Harald Haas during a TED Global Talk on Visible Light Communication (VLC). Professor Harald Haas is known as the “Father of LiFi”, and he is also the founder of PureLiFi, a pioneering company in the development of LiFi technology.

VLC uses light sources emitting at visible wavelengths between 400 and 800 THz (780–375 nm) to deliver high-speed communication, similar to Wi-Fi, and complies with the IEEE standard IEEE 802.15.7. LiFi is a subset of VLC and, as explained by Professor Harald Haas, uses the visible light spectrum instead of radio waves to transmit data. This approach opens up a vast spectrum — 10,000 times larger than the entire radio frequency spectrum. It’s a game-changer, offering the potential for faster and more secure data transmission.

How does LiFi work?

The process is intriguing yet straightforward. LiFi constitutes several light bulbs that form a wireless network. When an electrical current is applied to a LED light bulb, a stream of light (photons) is emitted from the bulb. The brightness of the light flowing through the LED bulbs can be changed at extremely high speeds, allowing the signal to be sent by modulating the light at different rates. The signal is then received by a detector that interprets the changes in light intensity as data. When the LED is ON, it transmits a digital 1, and when it’s OFF, it transmits a 0. The intensity modulation cannot be seen by the human eye, making the communication as seamless as other radio systems.

LiFi vs Wi-Fi

LiFi	Wi-Fi
Data transmission using light via LED bulbs.	Data transmission using radio waves via Wi-Fi router.
LiFi is connected to LED bulbs, and it does not require additional power consumption, thus reducing costs in homes and workplaces.	Wi-Fi requires electronic devices such as routers, modems, signal repeaters, wave amplifiers, and antennas, which consume energy 24/7.

1. Is LiFi just another name for Visible Light Communication (VLC)?

No, while both LiFi and VLC transmit data using LEDs, they are not the same. VLC is a point-to-point light communication network with controlled features operated at low or moderate data rates. On the other hand, LiFi supports high to ultra-high data rates and is bidirectional, unlike VLC, which is unidirectional.

2. Do lights need to be fully on for LiFi to work efficiently?

No, even if the lights are dimmed, LiFi will still work and transmit your data. The LiFi dongle is sensitive to low lights, and even the minimum level of luminescence can get this technology working.

3. Do the lights flicker a lot when using LiFi, causing headaches?

No, the current supply to the LED devices is modulated at a speed that is not perceptible to the human eyes. The flickering won’t cause headaches as it won’t affect us.

4. Is LiFi unidirectional?

No, LiFi is a full duplex communication technology that uses infrared energy for the uplink and visible light for the downlink.

5. Can LiFi work in sunlight?

Yes, LiFi can work in the presence of sunlight. Interference from natural or artificial sources can be reduced using optical filters, enabling LiFi to work even outdoors.

6. Does LiFi require ‘Line-Of-Sight’?

While the signal would be stronger in the presence of line-of-sight, LiFi can still receive data at a lower data rate if light levels are low. This means that line-of-sight is an advantage but not a necessity.

7. Does LiFi need special LEDs to work properly?

No, the current LED lights and ordinary lamps can perfectly work to provide light communication based on factors defining illumination.

8. Is LiFi a complex technology and cannot work with Wi-Fi?

No, LiFi is a simple technology that works on direct modulation and direct demodulation mechanisms. It is a cheap and highly efficient way of communication. Both LiFi and Wi-Fi technologies can coexist amicably.
