根据不同移动数据网络数据传输的特点结合地震数据的压缩算法，分析了不同采样频率和数据长度下使用移动数据网络进行地震数据传输的带宽需求,并得出计算公式。根据计算分析，得到平静期和发生大地震时不同的数据压缩率和带宽需求。得出利用移动数据网络进行数据传输的影响因素，总结了各种类型的移动无线网络传输地震数据的可行性。

We according various mobile communication networks and the algorithm of earthquake data, analysis the bandwidth requirement of earthquake data acquisition device in different sampling by mobile communication networks and the formula were obtained. And then we get the bandwidth requirement in the seismically quiescent period and the large earthquake occurred by calculates and analysis. Finally we summed up the feasibility of transmit earthquake data by mobile communication networks
