The CMAWireless (China Meteorological AdministrationWireless) provides the basis support services for the operational mobile office and video consultationHowever, the original CMAWireless service has a limited scope, and lacks of an authentication process with security risks It is difficult to achieve a meticulous management and cannot satisfy the requirement of future meteorological modernization In this paper, we use the redundancy network structure, stack of switch and dual system, WiFiprotected access, and wireless access point by power over Ethernet to study the characteristics of operational meteorological data transmission, and make up for the shortage of the original network based on WLCThe study provides a good support for the mobile office and video consultation
