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

Abstract

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].

An Adaptive Network Prediction and Judgment Method for Unstable Communication on Moving Medical Vehicles

“…To test and verify the network prediction and judgment method, several groups of wireless network speed data are collected using the implemented device [4], as Figure 2. Three kinds of 3G network provided by China Telecom, China Mobile, China Unicom are integrated in this device.…”

“…In existing work to deal with the unstable wireless network problem on moving medical vehicles, authors presented a multi-channel network platform, in which three kinds of 3G wireless network and two kinds of satellite network were integrated in one device [4]. The network quality was indicated by a light of each channel, thus network monitoring process was only accomplished by person according to the lights.…”
