As LiFi products and devices penetrate the global market, how will they affect the present internet infrastructure? Read on to find out!

Historical Development of LiFi

The LiFi or light Wifi technology is a brainchild of the German Physicist- Prof. Harald Haas. Haas introduced the term LiFi or Light Fidelity to describe his innovative use of light signals for wireless data transmission across space. He demonstrated this technology in a 2011 TED Talk, where he streamed a high-definition video with the help of a standard LED lamp.

Although Haas pioneered modern LiFi as we know it now, he was not the first person to experiment with the communication potential of optical signals. It was in 1880 that a beam of light was used to transfer data for the first time by Alexander Graham Bell. This revolutionary invention was called the Photophone, which was the first device to utilize modulated light for communication. The photophone served as an inspiration for the further development of optical communication technologies such as fiber optics, the VLC, and LiFi.

To understand how light-based communication evolved, let us go through some key milestones that led to the development of modern-day LiFi technology:

  • Initial Research into Visible Light Communication

    Early research into visible light communication tried to find viable applications for utilizing light as an electromagnetic wave that could transfer data across a system. Early experiments in this field explored the feasibility of modulating light signals to carry encoded data from a transmitter to a receiver.

    In 2005, a team of researchers began their study of VLC technology in the University of Paris Saclay. The goal behind this study was to identify ways to use light waves to establish secure wireless connections.

    In 2006, researchers at Pennsylvania State University used a combination of power-line transmission and LED technology to build a home broadband channel that also provided low-cost, efficient lighting.

    In 2008, the European Union set out to develop a high-speed network using the VLC system which was able to reach a transmission speed of 300 Mbit/s. This project was named OMEGA and it showcased the sophisticated data transfer potential of light signals.

  • Conceptualization of LiFi Technology

    Professor Harald Haas and his team of researchers began their experiments with VLC technology around 2006. The initial phase of their research was carried out at the University of Edinburgh, where they explored the use of light as a medium for two-way data transmission.

    After around 5 years of research, Prof. Haas’s work led to the innovation of LiFi as we know it now. This innovation was presented in 2011 in a TED Talk entitled “Wireless Data from Every Light Bulb”.

    In 2012, Prof. Haas started his own company to market the LiFi technology to a wider public. In the same year, researchers from the French University of Paris Saclay founded Oledcomm. This company went on to commercialize LiFi equipment in the telecom, datacom, personal electronics, and industrial markets.

  • Standardization and Product Development

    A rise in investor interest in LiFi led to the development of technology standards that support better interoperability between different LiFi devices and systems. Currently, the most popular standard for LiFi products is the IEEE 802.11bb standard, which has opened doors to the widespread adoption of light communication technology in the market.

    The adoption of standardized manufacturing protocols has encouraged faster commercialization of LiFi technology across different industries. The availability of commercial-grade LiFi transmitters, access points, antennas, and receptors in the market has facilitated easier deployment of LiFi networks in real-world environments.

The Mechanics of LiFi Technology

LiFi or light fidelity is a wireless communication technology that utilizes light-frequency signals to transmit data. Popular LiFi devices employ light waves from LED bulbs as their medium to deliver information across a network. As a subset of optical wireless communication technology, LiFi derives many advantages from the inherent nature of light waves. These include increased bandwidth, higher speed, reduced interference, and enhanced security which makes LiFi-based connections more preferable over traditional networks.

Let us understand how LiFi works by creating a light communication network in a few simple steps:

  • A LiFi network utilizes light from LED lamps for data transmission. Light signals encoded with information are modulated at a very high frequency to transmit data from their source. A single LiFi network can use multiple LED bulbs to create a zone of transmission that connects many devices.

  • A LiFi network is created when data transmitted from LED lamps is received and interpreted by a receiver in the nearby environment. Modulating light signals carries encoded data across a network, and this data is converted into electrical signals by receptors fitted in a LiFi-enabled device.

  • The retrieved electrical signals undergo processing to extract the encoded data in a form that is understandable for human users. Once the data is retrieved and converted into its final format, it can be easily accessed over LiFi-enabled devices such as smartphones, tablets, and laptops.

Advantages of Li-Fi over Conventional Wireless Connectivity

LiFi networks are now being preferred over conventional wireless systems for providing an upgraded connectivity experience to users. Here are some key advantages of using LiFi over traditional WiFi:

  • Higher Speed

    The speed of LiFi connections can be exponentially higher than the speed of a conventional WiFi system. Higher bandwidths and lower latency allow LiFi networks to provide a much faster data transmission rate. As a result, LiFi can deliver multiple Gbps speeds on mobile devices. The high-speed connectivity provided by LiFi Internet infrastructure allows it to provide better-quality video streams, downloads, navigation, and real-time calls.

  • Upgraded Security

    The physical characteristics of light waves allow them to be contained within a specific coverage zone, leading to more network security for a LiFi connection. As LiFi signals cannot be accessed by any devices outside their zone of connectivity, they are protected from being hacked or intercepted. Besides this, LiFi-based communication systems enable additional security controls such as asset tracking and user authentication.

  • Connection Stability

    LiFi internet is more stable and reliable when compared with traditional wireless connections. This is because LiFi doesn't experience congestion, or multi-user degradation which is a common problem with radio-frequency-based technologies. Further, LiFi signals are immune to interference from electromagnetic waves emitted by other devices in the environment.

Real-World Applications of Li-Fi

LiFi technology is set to revolutionize the efficiency and security of real-world communication systems. Here are some key areas that can experience major benefits from the application of LiFi:
