What is Wireless Fidelity: Comparing WiFi and LiFi Technologies

Understand what is wireless fidelity and how it compares with light fidelity. Learn the applications of LiFi and how you can leverage this powerful technology.

The demand for faster and more reliable internet continues to grow with an increasing need for high-speed connectivity. We've come a long way since the days of dial-up, with WiFi becoming an integral part of our daily lives. But what if there's an even better way to connect? Enter LiFi- the next revolution in wireless communication.

Before deciding if LiFi is the next big thing, it's important to understand how it stacks up against WiFi. In this article, we'll explore the inner workings of both technologies and uncover why LiFi might just be the future of our digital landscape.

What is WiFi?

So what is Wireless Fidelity? Wireless Fidelity, also called WiFi, lets your devices access the internet without wires through radio waves. It's based on IEEE 802.11 standards, which define the protocols for different frequencies and data rates. WiFi has become universal in homes, offices, cafes, and other common places. It has made a massive impact because of its convenience and ability to support multiple devices at the same time.

WiFi networks use a wireless router as the access point that acts as a bridge between the device and the internet connection. When connected with your device, this forms a network that can span across larger spaces and distances.

However, WiFi can suffer from interference from other electronic devices, physical obstructions, and even weather conditions. This can hinder your connection, especially when it matters the most, such as when you are in the middle of downloading something or in sensitive sectors such as defense. Despite these potential issues, WiFi is still reliable and widely used for everyday internet needs.

Does WiFi Really Mean Wireless Fidelity?

Surprisingly, "Wireless Fidelity" is not a technical term. It is more of a marketing term coined by Interbrand (a branding company). The name "WiFi" was used instead of IEEE 802.11b Direct Sequence. Whereas, "Fidelity" means high-quality transmission. WiFi has now become synonymous with wireless internet access and is a popular lexicon today.

Light Fidelity and LiFi Technology

LiFi, or Light Fidelity is a new wireless communication technology discovered by Harald Haas in 2011. It provides connectivity via invisible light and works by modulating LED light bulbs to send data signals. These signals are then converted back into data by the use of a device called the photodetector. Unlike WiFi which uses radio waves or wireless waves, LiFi incorporates invisible light spectrum, visible light spectrum, ultraviolet, and infrared so it can work in electromagnetic-sensitive areas where WiFi-connected equipment might face interference.

Applications of LiFi Technology

LiFi technology is relatively new and gaining popularity in different fields due to its benefits. Let’s discuss some key applications to understand how LiFI serves specific industries:

  • Healthcare

In hospitals and medical facilities, electronic interference with equipment can cause major disruption. Radio waves are the major cause of this problem. Light Fidelity doesn’t need radio waves and provides secure, high-speed communication.

  • Industrial Sectors 

LiFi's real-time communication capabilities can improve operational efficiency in industrial settings. For instance, in factories, it can enable faster and more reliable data transfer between devices.

  • Aviation

LiFi provides internet connectivity on planes at incredible speeds, which will greatly improve the in-flight experience for passengers. They offer high speeds and relatively high reliability, all without posing a threat to the aircraft’s navigation systems.

  • Military and Other Secure Environments

LiFi connectivity maximizes cybersecurity, making it ideal for use in the defense sector, law firms, government agencies, and other secure environments where data privacy is paramount. Its application in the military sector is particularly noteworthy. By minimizing the risk of cyber attacks, military command and control centers can leverage LiFi for better wireless network security.
