A network of the emergency telemedicine for mountain climbers in Japan Alps area has been developed. The network consists of 2.4GHz wireless LAN with over 30 km distance to be connected the Cable TV LAN. We confirmed that this network is able to transfer the high quality video and audio signal suitable for the telemedicine between the mountain huts and hospitals. In this paper, we pointed out the shortcomings of wireless LAN system and cable TV network system in use, for the telemedicine, and wireless LAN module covered more than 30km and a extension system of upstream frequency bandwidth for Cable TV network. Experiments suggested that a low cost and long distance wireless LAN is useful for mountain climber's emergency telemedicine.
