    Abstract: 近年來無線網路的蓬勃發展,日常生活中隨處可見的行動裝置也能夠使用無線網路進行資料的傳輸,使得各種無線設備不斷地推陳出新,因此無線網路的技術也不斷提升、改變。在無線區域網路(Wireless Local Area Networks, WLANs)的範疇當中,可以說使用性非常之高。在IEEE 802.11ac標準中提出了新的技術提升無線網路的傳輸速度,並達到一高速網路的環境。本論文中,主要分析兩個存取點在使用不同頻寬做為傳輸時,根據兩個存取點之間的距離,對彼此之間的傳輸所產生的影響與結果,使用分析數據所產生的參數(碰撞組合、公平競爭組合、Degree數與達成平行傳輸所需要的頻道數量)來進行分群,透過分析參數以及本論文所擬訂的分群機制,可以使得多個存取點得以同時進行傳輸,最後再透過有效的頻道配置方法,達到碰撞避免及平行傳輸。
    With the rapid development of wireless networks, the number of channels that can be used in a large number of transmission can be said to be quite small. Therefore, how to use effective channel configuration methods to improve the overall network performance and mitigate data collisions. And further to achieve the purpose of parallel transmission.
    This paper investigates the allocation problem in dense deployed IEEE 802.11ac wireless local area networks (WLANs). How to use the effective channel allocation method to improve the network as performance, ease data collision problem, and further achieve the purpose of parallel transmission. In this paper, the main analysis of two access points in the use of different bandwidth as a transmission, according to the distance between two APs, the transmission between each other and the results of the use of analytical data generated. By analyzing the parameters and the grouping mechanism proposed in this paper, multiple access points can be transmitted at the same time.
