Abstract

Abstract

En 中文
In reality, both mobile and fixed nodes are required in wireless light communication networks. Dynamic maintenance of light alignment plays a key role in mobile full-duplex light communication. Here, we merge an image identification module and a light communication system on a three-axis gimbal stabilizer. A real-time image of the other light communication system obtained by the image identification module is used as a feedback signal to control the three-axis gimbal stabilizer. Therefore, the other light communication system is automatically tracked, and the optical path between the two light communication ends is dynamically maintained, leading to mobile full-duplex light communication under the transmission control protocol/inter net protocol (TCP/IP) scheme. Two green light communication apparatuses are separately deployed on two moving vehicles to establish bidirectional light transmission between moving network nodes with a maximum modulation bandwidth of 4 Mbps. Video communication across air and underwater environments is demonstrated, and internet access is illustrated via a Wi-Fi modem. To overcome environmental barriers, we combine mobile green light communication with blue laser communication, deep-ultraviolet light communication, and 850 nm laser diode communication to develop a mobile all-light communication network that enables seamless connectivity across air, land, and underwater environments. Since this network architecture is based on full-duplex communication, all communication nodes have equal and complete mapping characteristics and can facilitate bidirectional real-time data transmission between arbitrary nodes within the network, offering a promising route toward seamless mobile connectivity using light regardless of the environment.
