在各項微波傳輸技術中，LMDS可以說是最受到注目的，因為它可以提供雙向的語音、影像及數據傳輸的寬頻整合服務。LMDS能夠滿足各類型的用戶分佈與應用，從住家到商業用途均能提供服務，因此更具有彈性及擴充性。台灣在大前年(2000)三月十九日發放固網執照，即使有線寬頻傳輸應是其競爭的主軸，然而仍有業者藉助固定無線傳輸技術的應用，以提高其競爭力。由此可窺知LMDS的發展潛力。
為了有效降低LMDS中細胞間干擾的問題，本論文提出新的細胞規劃，可以獲得較少的細胞間干擾，相關的分析討論詳見第二章、第三章。第四章，分析分碼多重擷取加上功率控制的技術，以減少使用者受到的干擾。第五章是結論及討論。

LMDS is the most obtrusive among mini-meter wave propagation techniques. Because it can provide wideband integrated services including two-way voice, video, and data transmission. The asymmetry between downstream and upstream is quite consistent with the normal data flow, particularly for residential applications. Of course the spectrum can also be used to provide symmetric traffic that would typically be required for business applications.
In chapter 2, we use cells planning, which suffers less inter-cell interference in comparison with the typical cell planning. Chapter 4 analyzes the technique of CDMA with power control scheme can reduce inter-cell interference effectively in clear air. Besides, high rainfall attenuation is a significant challenges associated with deploying systems at Ka band. Finally, chapter 5 gives the conclusions.
