Study On WLAN Wireless Access Network Planning And Performance Optimization

The earliest WLAN was be introduced as complementary finite LAN means, but the development of wireless LAN in scalability, mobility, transmission speed, safety of the retainer are continuously, has been able to make multiple users, large capacity, wide coverage of wireless network management to meet the requirements of. Wireless LAN is also supplemented by Limited Lan means gradually evolved into the public wireless local area network operation, expanding coverage area, number of users, increase the capacity of the network, have led to the wireless network planning gradually become the outstanding problems in the construction of the public wireless local area network.WLAN wireless network planning according to the demand for capacity, coverage requirements and other special requirements, and local geomorphological features combined, will be reasonable network layout design, with the lowest investment makes the current needs are met, and to ensure that the network to facilitate the expansion in the future.For WLAN, its performance is mainly decided by three aspects, namely:the quality, coverage and capacity constraints, a relationship exists between them,. The WLAN access performance optimization, choose according to the user requirements to ensure that the network performance, user can meet the requirement of. So WLAN optimization must consider comprehensively. This paper firstly discusses the WLAN network planning, and discusses the planning method, and the optimization focuses on the coverage optimization, parameter optimization and frequency optimization, network equipment is also discussed in this paper, study on the optimization strategy and technical method, including the related main techniques:cover design, propagation prediction, the capacity of the channel and frequency optimization, wireless access equipment performance optimization.
