In emergency telemedicine system based on wireless communication system with limited transmission capacity, it is necessary to transmit the biological data (ECG, IBP, Respiration, S_PO₂) of the patient continuously and reliably in real time. For this service, it is necessary to data compression and error control. In this study, we designed an ARQ based protocol for error control in application layer and implemented it on the biological data transmission program for an emergency telemedicine system based on wireless data communication system. For an experiment, Used IS-95C based wireless mobile communication service and ADSL based cable transmission service.
