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.
