The onboard MESH self-organizing network equipment is small in size and light in weight. It can be installed either upright or upside down, making it convenient for installation. It is particularly suitable for application scenarios such as unmanned aircraft that have lightweight networking requirements. It can dynamically form a network in the air and quickly establish an interconnected three-dimensional network with handheld/soldier systems, vehicle-mounted systems, and surrounding base station networking equipment, achieving efficient collaboration.
