GaN micro-LEDs have been spotlighted as promising candidates for high-speed optical communication, which may become important components in 6G communication blueprint. To achieve a superior network covering sea, land and air for 6G communication, we demonstrated cross-medium communication based on an 80 $\mu$m double-sided emission micro-LED array. The high enough light output power radiated from both sides of the green micro-LED enabled interference-free signal transmission in different media. Data rates of 1.55 Gbps over the 3 m free-space link and 1.11 Gbps over the 3.4 m underwater link could be achieved simultaneously. Furthermore, parallel-connected micro-LEDs were utilized to demonstrate the feasibility of pattern display and communication, and expected to achieve longer communication distances in media such as underwater channels.
