Optical Wireless
Optical Wireless is a communication technology that uses light, typically infrared or visible light, to transmit data wirelessly without radio frequencies. It enables high-speed, secure data transfer over short to medium distances, often in line-of-sight configurations. Common applications include Li-Fi (Light Fidelity), free-space optical communication, and infrared data transfer.
Developers should learn Optical Wireless for applications requiring high bandwidth, low latency, and enhanced security in environments where radio frequency interference is a concern, such as hospitals, aircraft, or secure facilities. It's particularly useful for IoT deployments, indoor positioning systems, and supplementing Wi-Fi in dense urban areas to alleviate spectrum congestion.
