Analysis And Design Of Wireless Local Area Network Management Systems Reeducation-Through-Labor Administration Of Heilongjiang Province

In this "Network is computer" age, accompanied with the widely use of local area networks, WLAN technology is also rapidly developing to provide a fast highly effective and flexible network. Currently, wireless correspondence and data correspondence have become the two major potential growth areas. Wireless data correspondence business has become the focus of attention as its both features.Faced with the opportunities and challenges, we should not only stick to cable position, but also should clear our mind, take the initiative and use of "first LAN, then WLAN" development strategy. Firstly, proceed from the WLAN and wireless network operators continue to accumulate experience for the future of wireless communications to the field and prepare for a comprehensive infiltration. Actually, the WLAN building is of strategic importance. Meanwhile, as the cable access means a supplement to meet user’s demand for broadband access, diversity and construction of WLAN is extremely meaningful and important.The mainline of this paper is WLAN’S design and construction of Heilongjiang Province education-through-labor administrative. Analyze the design and construction of WALN from five perspectives. Theory with practice, it was not only noted that the relevance of the characteristics of WLAN and principles, but also the practical application, explores building a network planning process. The five areas are as follows:The introduction of this paper focus on the significance and background of WLAN study.The WLAN research’s circumstances at home and abroad. Major research contents of this paper are introduced as well.The second part of this paper mainly provides a brief introduction about WLAN’S design and construction of Heilongjiang Province Education-through-labor administrative, includes technical requirement, security issues, principals of design and design flow. The third part goes from the demands of system, expounds the demands of WLAN and particular demand of the system.The fourth part focus on the analysis and design of system’s actual eonstruct, search specific solutions to particular issues.Moreover, specifically investigate security issues and expound the precautionary measure.There is still spacious room for the development of WLAN. From the standard view, as for802.11a and802.11g, the physical layer data rate is54Mbit/s.Because of consumption of the system, data transmission’s actual speed (data throughput) is only30Mbit/s. The new802.1In standard is intended to improve efficiency, and attempts to increase the use of physical layer data channel, and raise the speed.With WLAN networks available to the entire user, the importance of network planning will become increasingly prominent. WLAN network planning requires practical work to become more perfect, and develop with the further development of WLAN, towards high-performance, security, carrier-class objectives of the network trend.
