The Design And Implementation Of Security WLAN In Power Company

Wireless Local-Area Network(WLAN)is the wireless implementation based on the rapid development of network and telecommunication technology.Since WLAN uses high-frequency radio waves rather than wires as the transmission media,it performs as a supplement and extension of wire-connected LANs.With the deepening applications of office automation,mobile office technology,a company intended to build a fast,flexible,reliable,high-security WLAN system carrying rich mobile applications.In this paper,the methods for designing and construction an advanced,secure,and easy-to-use wireless intranet according with the requirements of electric power company are recommended.And a power company office area as an example to complete the construction of WLAN of electric power company,system establish and operation.Firstly,the overall demand for electric power company WLAN is deeply analyzed.The principle the technology of Organizing WLAN are studied,including wireless access technology,wireless network technology,wireless security protocols and wireless user authentication technology,etc.According to the business requirements and security needs,a WLAN networking technical scheme is proposed,which adapts to requirement of electric power company production and safety.In this paper,also the framework of electric power company WLAN is planned in several areas such as the WLAN network architecture design,IP address planning,attenuation and frequency point distribution design,wireless SSID planning,and wireless network safety design.According to the power company construction of WLAN design points,this paper intends focus on the installation and deployment of the selection of major equipment and core network firewall,network switches,wireless controller,wireless AP,AD domain system,wireless access system,and DHCP system installation and deployment.These aspects describe the construction and implementation of WLAN and provide the theoretical and technical support for the construction of the electric power company WLAN.The electric power company WLAN was tested in detail.It confirmed that the building WLAN has high usability and security,all test indicators have reached the expected standard and fully meet the power company production and safety requirements by the wireless network availability,wireless signal,and wireless network access security test and analysis.Finally,the design and implementation experience of electric power company WLAN are summarized.The problems that need to be solved in electric power company WLAN are pointed out.And the future development directions of electric power company WLAN are looked forward.
