The prototype’s ability to maintain seamless connectivity even with moving communication nodes marks a significant leap forward in communication technology.
The Birth of a Mobile All-Light Communication Network
Dynamic Optical Path Alignment
One of the most significant challenges in developing a mobile all-light communication network is ensuring dynamic optical path alignment. This is crucial for maintaining uninterrupted connectivity between moving nodes. The research team, led by Yongwin Wang from Nanjing University of Posts and Telecommunications in China, tackled this issue by constructing an image identification module coupled with a full-duplex light communication module. Both components were mounted on a three-axis gimbal stabilizer, allowing the system to dynamically maintain precise optical path alignment. This setup enables continuous bidirectional data transmission under the TCP/IP protocol, ensuring reliable communication across different environments.
The ability to dynamically align optical paths is particularly challenging given the various factors that can disrupt light transmission, such as environmental conditions and the relative motion of communication nodes. The image identification module plays a pivotal role in continuously tracking and adjusting the optical paths in real-time. By employing advanced algorithms and image processing techniques, it ensures that the full-duplex communication module can maintain a stable connection even when the nodes are in motion. This technology not only enhances the reliability of the communication network but also opens up new possibilities for its application in dynamic and challenging environments.
Integration of Cutting-Edge Technologies
The prototype network integrates several advanced technologies to facilitate robust data exchange. These include mobile green light communication paired under the TCP/IP scheme, blue laser underwater communication, a deep ultraviolet light communication system, and an 850-nm laser diode communication system. Each of these technologies plays a crucial role in ensuring seamless connectivity across various environments. The systems are interconnected through Ethernet switches, providing access to various terminals, including sensors and personal computers. This integration of technologies ensures that the network can handle data reception and transmission efficiently, regardless of the environment.
Mobile green light communication is ideal for terrestrial applications, offering high-speed data exchange between moving vehicles or other mobile nodes. In contrast, blue laser underwater communication is tailored for aquatic environments, where water absorption of different light wavelengths can pose significant challenges. The deep ultraviolet light communication system provides “solar-blind” wireless data transmission, effectively avoiding the interference caused by solar radiation, which is crucial for outdoor applications. The 850-nm laser diode system further enhances the network’s capability to manage data transmission across various mediums. By interconnecting these diverse communication systems, the prototype network can maintain seamless operation across a spectrum of challenging conditions.

These tests were carried out under various conditions, including nighttime and full sunlight on an outdoor lawn, as well as within an indoor water tank. The trials demonstrated the network’s ability to maintain bidirectional light transmission across air and underwater environments with a maximum modulation bandwidth of 4 Mbps. This bandwidth is sufficient for video and audio transmission, highlighting the network’s potential for real-world applications.
The rigorous testing protocol covered a range of environmental conditions to ensure the network’s versatility and reliability. During nighttime and full sunlight tests on an outdoor lawn, the network demonstrated its ability to handle varying light levels without losing connectivity. These tests also highlighted the system’s resilience against potential obstructions and environmental interferences. Underwater tests in an indoor water tank showcased the network’s blue laser communication capabilities, which proved effective even in a medium known for its high light absorption rates. This comprehensive validation process underscored the network’s robustness and its potential to be deployed in diverse real-world scenarios.
