Development of Satellite/3G+ Multi-Link Communication Terminal Based on Medical Rescue Information System

This paper introduces a satellite /3G+ multi-link communication terminal based on medical rescue information system, which provides 3G wireless network and satellite communication services and integrates cellular phone, maritime satellite terminal, BeiDou user device and Iridium phone [1]. The new terminal could improve the communication adaptability and transmission efficiency for the emergency medical rescue information system even in hostile environmental conditions [2] (such as earthquake, flood, and war). Tests showed that: this terminal has the advantages of simple access, rapid switch, efficient transmission, it can also guarantee timely and effective interaction of all kinds of information, so as to ensure the time-effect treatment for emergency medical rescue system [3].
