摘　　要：针对2G网络速度慢,且在很多偏远山区信号弱并逐渐被3G、4G网络取代的现实,作者设计了一款基于3G网络的无线通讯终端,具有良好的可扩展性,经实际使用证明数据传输稳定可靠,解决了区域地震台网偏远山区的数据传输问题。In many mountainous areas the 2G signal is weaker, and its speed is slow, so the low speed traditional 2G mobile network is being replaced by 3G 4G gradually. To solve the problem of data transmission of regional seismic network in such mountainous area, the paper designs a wireless communication terminal based on 3G mobile network, which has a good expandable module, and is proved to be stable and reliable in data transmission.
