【 摘 要 】

In this paper, we selected the VPN tunnels based on wireless 4G network card or fiber broadband, MSTP digital optical fiber and other communication methods, using the seismic station in Hunan Province to set up seismic observation instrument, at the same time, the same location compared to the above communication mode To the observation data, analysis of data transmission test results, selected the best mode of communication for the new seismic stations or replace the existing seismic stations to provide a reference for communication.
