Abstract
The medical service with a high data rate can be supported in mobile emergency telemedicine system by development of cellular communications networks. In Korea, the commercial service of CDMA2000 1X-EVDO is provided since 2002. In this paper, we designed the system that transfers biological signal and video signal information of patients simultaneously based on this communication network environment. In CDMA2000 1X-EVDO, the maximum backward speed is observed to be 153.6Kbps. Several field tests are performed using commercial CDMA2000 1XEVDO to realize the emergency telemedicine system fitted to feature of CDMA2000 1X-EVDO. With the designed system, we could transmit biological signals and MPEG4 images of spatial resolution 640x480 simultaneously. We set up the system in an ambulance and tested it on the road.
