Since March 2020, 5G has been commercialized mainly in urban areas in Japan, and 5G communication infrastructure demonstration tests are actively conducted among various industries such as telecommunications carriers and construction industries. The authors installed a portable 5G base station close to tunnel portal in "Subcontracting for research and study of technical conditions, etc. for a fifth-generation mobile communication system (Hereafter, 5G) .This can handle simultaneous connection requests from various terminals" (Hereafter, 5G demonstration experiment) of the Ministry of Public Management, Home Affairs, Posts and Telecommunications in fiscal 2019, and constructed a high-quality radio wave environment in the tunnel pit, and carried out various experiments to improve working environment such as safety. This paper describes an experiment in which a long-distance running and lifting work of a construction machine succeeded by remote control, while a high quality radio wave environment was constructed in a tunnel construction site by 5G, and clear multiple images which can surely carry out remote control, and other support information were acquired.
