After the 2011 Great East Japan Earthquake, the resource utilization of and the problems encountered with communication devices were examined.
A questionnaire survey was submitted to disaster medical assistance teams (DMATs) that were at the primary sites of destruction after the earthquake.
We collected data from 196 teams. During the first 4 days after the earthquake, the use of mobile phones, laptop computers, and landline phones was rated as poor to moderate, and satisfaction was very low, while satisfaction with satellite phones was rated as good to moderate (50%). The degree of satisfaction continued to increase gradually over time. Satellite phones, however, had several problems: poor reception, line instability, voice call use only, and inability to send large amounts of data.
To ensure effective communication during the acute phase in the aftermath of large disasters, a new satellite communication device is needed that not only is portable, battery powered, and able to send large volumes of data, but also offers stable communication.
在2011年东日本大地震后，对通信设备的资源利用情况及遇到的问题进行了调查。
向地震后处于主要受灾地点的灾害医疗援助队（DMATs）发放了问卷调查。
我们收集了来自196个团队的数据。在地震后的头4天里，手机、笔记本电脑和固定电话的使用情况被评为较差至中等，满意度很低，而对卫星电话的满意度被评为良好至中等（50%）。满意度随着时间的推移持续逐渐提高。然而，卫星电话存在几个问题：信号接收差、线路不稳定、仅能进行语音通话以及无法发送大量数据。
为确保在重大灾害后的急性期进行有效通信，需要一种新型卫星通信设备，它不仅便于携带、由电池供电且能够发送大量数据，而且还能提供稳定的通信。
