“Wireless Telemeter System” was built, which can transmit the video and data simultaneously, by wireless in order to contribute to labar saving and informational construction technology in the tunnel field. This system can transmit both the video information and measuremental data in real time by SS (Spread Spectrum) wireless from the tunnel field to office. And SS wireless which is not influenced by noise and which can be transmitted in long distance is new wireless technology. This paper discribes the abstract of this system and the result of experiments to use this system in the tunnel field.
