Breakthrough in optical communication technology, the first LED lighting panel with Internet access has been released
In recent years, as mobile networks and smart devices have advanced rapidly, along with the expansion of related services, consumers have become more demanding in terms of network speed and capacity. This has led to the rise of optical communication technology. Currently, fiber optics is the most widely used form of optical communication, where light-emitting diodes (LEDs) or laser diodes (LDs) serve as transmitters.
Now, a new era of optical communication is emerging—Li-Fi technology. Unlike traditional Wi-Fi, which relies on radio waves, Li-Fi uses visible light, such as LED, infrared, or near-ultraviolet light, as its transmission medium. By combining lighting and communication, Li-Fi has the potential to become a key technology in smart homes. It offers faster data transfer speeds and avoids electromagnetic interference, making it a promising alternative to current wireless technologies.
At this year’s Consumer Electronics Show (CES) in the United States, Li-Fi made significant progress. A U.S. company, VLNComm, unveiled the first Li-Fi-enabled LED lighting panel at the event. The product, called "LumiNex," can deliver download speeds of up to 108 Mbps and can be paired with a "LumiStick" device that supports an upload speed of 253 Mbps. The system covers an area of approximately 516 square feet. It uses standard white LEDs and can support up to 15 users simultaneously online.
According to Professor Noshad, CEO of VLNComm, this development marks a major step forward. As the technology continues to evolve, Li-Fi could offer greater security and access to available spectrum, potentially complementing or even replacing Wi-Fi in the future.
Although Li-Fi has some limitations—such as the fact that light cannot pass through walls and the coverage of each light source is limited—it offers higher security compared to Wi-Fi. Since it doesn’t use radio waves, it is less prone to interference or eavesdropping. This makes it particularly suitable for environments like supermarkets, hospitals, and even deep-sea sensors, where secure and reliable connectivity is essential.
As the demand for faster and more secure internet grows, Li-Fi is positioned to play a crucial role in shaping the future of wireless communication.
