摘要

在無線電波傳播環境中，天線因子與路徑損耗對通訊的品質扮演相當重要的腳色，在本論文中，主要針對WLNA無線網路MIMO多天線之電波傳播的接收功率進行分析與探討，並且驗證在透過MIMO與Beamforming的天線技術，可以有效提升WLAN無線網路的傳輸品質。實驗的環境是針對室外與室內環境的電波傳播路徑進行一系列的測試分析，主要的實驗架構在比較 MIMO 與 Beamforming 天線的訊號在通過不同材質的阻隔物與距離下，經過多路徑衰減後接收功率的比較，藉以分析MIMO與 Beamforming 不同的天線模式下，於辦公室、學校、住家等各種日常生活環境中，無線通訊傳輸效能的差異。

In the radio wave propagation environment, the antenna factor and the path loss on the quality of communication play very important roles. In this paper, we focus on the analysis and discussion of WLNA MIMO wireless communication multi-antenna reception power of the wave. We also verify if MIMO and Beamforming can effectively improve the transmission quality of wireless network WLAN through the antenna technology. Experimental environment is a series of testing for outdoor and indoor radio propagation path. The main experimental framework is to compare MIMO and Beamforming antenna signal through the barrier properties of different materials and distance. By comparing the received power under multi-path, we could analysis the performance difference of communication transmission between MIMO and Beamforming in different antenna mode, at home, in the office, school and other places.
