The Constitution Of Police Station WLAN System

The geographic position where the county of Wulateqian is more special,and Wula mountain is located in it and separates eight police substations. The complexity of the geography leads to the result that we have to choose Wireless technique, because it costs less and supports the communication in the distance. Under the background like that, this topic introduces how to construct a four-tier network using Wireless Local Area Networks technique. After making practicable assessment, we can get the distance between the police substations according to practical survey, and then decide to the method of connection between every point and the specific network topology. After installing the equipment and debugging errors, we link all police substations together at last and access Public Security Network. The entire local area network should have the following features: 1.To resolve the problem of wireless network connectivity in complex environment (mountainous region); 2.To share the information and resources in the network; 3.To provide an open platform for the common local area network; 4.To achieve the functions of back support and video transmission; 5.To support the security and confidentiality of data in the network transmission; 6.To own the automatic directional antennas; 7.The system has strong anti-jamming capability; 8.The system must have a higher stability; 9.To maintain a simplified interface.
