A new frontier in connectivity is emerging from the lighting industry. LiFi, or Light Fidelity, is a wireless communication technology that uses light waves from LED bulbs to transmit data at extremely high speeds. Unlike traditional Wi-Fi that relies on radio frequencies, LiFi offers a more secure and interference-free connection, as light cannot penetrate walls. This makes it ideal for environments like hospitals, airplanes, and secure government facilities where radio signals are problematic. Several companies are now developing commercial LiFi products, integrating the technology into standard office and industrial lighting fixtures. While challenges such as line-of-sight requirements and ecosystem development remain, LiFi presents a compelling complementary technology to RF networks. As the Internet of Things expands, the demand for localized, high-bandwidth, and secure data transmission could propel LiFi from a niche innovation into mainstream adoption, fundamentally changing our understanding of what a light fixture can do.
