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 an 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.
日本阿尔卑斯山区已建立了一个针对登山者的应急远程医疗网络。该网络由距离超过30公里的2.4GHz无线局域网组成,用于连接有线电视局域网。我们证实,这个网络能够在山间小屋和医院之间传输适用于远程医疗的高质量视频和音频信号。在本文中,我们指出了用于远程医疗的无线局域网系统和有线电视网络系统的缺点,以及覆盖超过30公里的无线局域网模块和有线电视网络的上游频率带宽扩展系统。实验表明,低成本、长距离的无线局域网对登山者的应急远程医疗很有用。
