By analyzing meteorological operation characteristic of strong timeliness and 7 ×24 h continuous running, combining with the situation of Hainan province meteorological network structure, the paper fully taps the function of wireless network, further studys the backup means of ground surface broadband based on 3G VPDN technology, plans and designs the VPDN line backup programs based on 3G, achieves high availability of province-city and county meteorological network. The paper elaborates network way and equipment function, and gives key configuration code. The network has already putted into operation one year, no matter daily business or major meteorological security, the network achieves good results.
