Visible Light Communication (VLC) is emerging as a high-potential wireless communication technology that uses modulated visible light from LEDs to transmit data while maintaining illumination. Positioned within the broader optical wireless communication ecosystem, VLC is gaining relevance as connected devices, smart lighting, indoor positioning, industrial automation, and secure short-range communications expand across commercial, public, and mission-critical environments. Unlike radio frequency systems, VLC operates in the visible spectrum, reducing electromagnetic interference concerns and making it suitable for settings such as hospitals, aircraft cabins, factories, classrooms, transportation hubs, and underground facilities. Its alignment with energy-efficient LED infrastructure gives the technology a practical pathway for integration into lighting, sensing, localization, and data transmission applications. As digital infrastructure becomes more dense and spectrum congestion intensifies, visible light communication is increasingly viewed as a complementary connectivity layer that can support high-speed, localized, and secure data exchange.

The visible light communication landscape is being reshaped by advances in LED lighting, photodetectors, image sensors, modulation techniques, and integrated optical wireless systems. Smart buildings are accelerating the convergence of lighting and connectivity, enabling ceiling fixtures, luminaires, and signage to function as communication nodes. In transportation, VLC is being explored for vehicle-to-vehicle and vehicle-to-infrastructure signaling, particularly where light-based directional communication can enhance situational awareness. Retail, museums, airports, and healthcare facilities are adopting indoor positioning concepts that use light signals for navigation and asset tracking. At the same time, Industry 4.0 environments are evaluating VLC for low-interference machine communication in areas where radio frequency emissions are restricted or unreliable. Standardization activity, including IEEE 802.15.7-related optical wireless communication frameworks, is supporting interoperability and technical maturity. These shifts indicate a movement from laboratory validation toward practical deployments that combine illumination, localization, sensing, and communication in unified infrastructure.

Artificial intelligence is strengthening visible light communication by improving signal processing, channel estimation, adaptive modulation, beam alignment, interference mitigation, and network optimization. AI-enabled algorithms can help VLC systems respond to changing indoor environments, including user movement, shadowing, reflections, lighting variation, and dynamic traffic patterns. Machine learning techniques are also being used to improve indoor positioning accuracy by analyzing light signal fingerprints, sensor fusion inputs, and environmental context. In smart buildings and industrial facilities, AI can coordinate VLC links with Wi-Fi, 5G, Bluetooth, and other connectivity layers to maintain resilient hybrid networks. Computer vision and image sensor-based VLC can further benefit from AI by enhancing decoding performance under variable illumination and motion conditions. The cumulative impact of artificial intelligence is not limited to performance gains; it also supports predictive maintenance of connected luminaires, intelligent energy management, automated network configuration, and stronger cybersecurity analytics for light-based communication systems.
