FAQs

What are the benefits of LiFi? ›

LiFi is a wireless technology that holds the key to solving challenges faced by WiFi and 5G. LiFi is fast, more reliable, virtually interference free and uniquely more secure than other wireless communications technologies.

LiFi communicates using visible light, which is beneficial in more ways than one. These waves can carry significantly more data than the traditional radio waves used in WiFi technology. The visible light spectrum is nearly 10,000 times larger than the radio wave spectrum.

Yes, Li-Fi is considered better than Wi-Fi in terms of security, latency, health impact, stability, and interference. What is LiFi Internet? Li-Fi, or Light Fidelity, is a wireless communication technology that uses visible light to transmit data, providing high-speed, reliable, and secure internet connectivity.

Need for Special Hardware: LiFi needs special LED bulbs for transmission and photo-detector for reception. The need for special LED bulbs has made it difficult to implement LiFi on a large scale as these bulbs are not yet mass produced.

WiFi transmits data using radio waves, whereas Li-Fi uses light, typically from LED bulbs, to transmit data. Li-Fi operates at a frequency spectrum about 10,000 times higher than WiFi, offering potentially higher data transmission speeds.

LiFi technology has several advantages over WiFi. First, it offers higher data transfer rates, with speeds up to 100 times faster than WiFi. Second, it is more secure, as the data is transmitted through a physical medium (light waves) that cannot penetrate walls, making it much harder for hackers to intercept the data.

LiFi technology will allow us to connect to the internet using light from lamps, streetlights or LED televisions. In addition to being cheaper, safer and faster than wifi, it does not need a router.

Since Li-Fi uses just the light, it can be used safely in such locations or areas. In future with the Li-Fi enhancement all the street lamps can be transformed to Li-Fi connecting points to transfer data. As a result of it, it will be possible to access internet at any public place and street.

At its core, LiFi technology uses LED bulbs for light communication that transmits wireless signals. They have a long lifespan, are durable, mercury free, recyclable, and incredibly energy efficient, making them a very sustainable option for wireless connectivity.

While Li-Fi will probably never be a viable option to replace consumer grade Wi-Fi connections, it is not completely dead. There are various applications where Li-Fi makes a lot of sense.

Is LiFi can be hacked? ›

Light waves can't pass through walls and other objects, which makes it more secure than WiFi. LiFi is more secure for the simple fact that it is contained in a single room and a hacker would have to have access to the room to hack into it.

Another perceived disadvantage of LiFi connections is that because it relies on light to transmit data, it becomes highly susceptible to outside interference. Photodiodes are able to pick up light from competing sources of light such as sunlight and other forms of illumination.

Limited Range: LiFi was created with the goal of replacing traditional WiFi systems in order to enhance bandwidth. However, there is a serious flaw in LiFi's underlying idea of using light to transmit data. It restricts LiFi's range.

LiFi can operate in daylight and even in direct sunlight conditions, as the modulated light can still be detected. LiFi relies on detecting the fast changes in light intensity and not on the absolute or slowly varying levels caused by natural disruptions in daylight or sunlight.

Disadvantages of Li-Fi technology include: Internet cannot be used without a light source. This could limit the locations and situations in which Li-Fi could be used. Because it uses visible light, and light cannot penetrate walls, the signal's range is limited by physical barriers.

Unlike WiFi, LiFi operates in the visible light spectrum, meaning it produces no electromagnetic interference and poses no risk to sensitive equipment or human health. By minimizing electromagnetic pollution, LiFi contributes to a cleaner and safer environment.

In healthcare, for instance, LiFi can enable secure, real-time monitoring and communication of patient data, enhancing both the quality and efficiency of care. In educational settings, it promises to transform the learning environment by facilitating an interactive, engaging, and connected classroom experience.
