WLAN Design Of Huai’an Hotel Based On IEEE 802.11ac

With the development of wireless network technology,WLAN application based on IEEE802.11 ac protocol standard has been more and more widely used in various scenarios.The design of this thesis is mainly based on the WLAN project and maintenance of Jiangsu Mobile Huai’an branch.The research significance of this thesis is to solve the problems of slow speed and insufficient support for online users existing in the current hotel WLAN system of the company,and explore the networking design and construction scheme of hotel WLAN System Based on 802.11 ac standard.The key design content and my key research work are mainly elaborated through the following aspects:Firstly,this thesis summarizes the current WLAN protocol standards and key technical indicators,including WLAN protocol standard evolution,2.4GHz and 5GHz band channel planning,rate calculation empirical formula,AC networking technology.The handover algorithm between LTE and WLAN is studied.Secondly,the mathematical model of AP signal coverage based on channel overlapping interference and Signal to Interference plus Noise Ratio is analyzed and studied,and the objective function for hotel WLAN AP deployment is formulated.On this basis,the AP deployment and simulation of hotel lobby,banquet hall and guest room are carried out by using genetic algorithm.Thirdly,the hotel WLAN network is planned,and the AC and AP network based on local data forwarding is determined.The AP selects the thin AP which supports IEEE 802.11 ac protocol standard;The transmission network uses PON network.The configuration method of local forwarding parameters is also described.In addition,hotel WLAN can also achieve seamless roaming,authentication and network congestion control between APs.Finally,through the example of Huai’an Hotel WLAN reconstruction project,the feasibility of the hotel WLAN construction scheme based on IEEE802.11 ac technology is verified.The AP,AC,convergence switch and other equipment of Ruijie manufacturer are used in this reconstruction,and the networking planning and AP coverage installation design are carried out.After the completion of the construction,the data of AC and access switch are configured and the parameters of AP are set.After the equipment debugging.AP was successfully launched.The construction effect of hotel WLAN was tested by using Wireless Mon,Wi Fi analysis assistant and Speedtest software.The test results are analyzed by BP neural network algorithm.
