dc.description.abstract | 本研究藉由探討常用的技術預測十二種方法,辨識影響技術預測的因素並釐清應用不同預測方法的限制與相互間的關係。並依據被預測技術的資料有效性、技術及環境的不確定性及該技術發展期間等三個構面,整理出不同情境技術預測方法的選擇建議。 我國於1997年1月公佈了民間行動電話通信業務的執照,從此台灣的行動電話進入了自由化的時代。但是國內業者能爭取的商機卻是有限,主要的原因是技術能力與時間不足。因此,本研究以無線通信數位化擴散程度為個案實證的主題,期使能更清楚未來無線通信數位化的技術趨勢。 經由選用技術預測方法的三個構面,選擇成長曲線作為技術預測的實證模型,預測無線通信第一代類比式到第二代數位式的擴散時間點,並推估通信接取技術CDMA替代TDMA的時間點。最後,輔以分析TDMA/CDMA的專利,藉以驗證、比較未來的技術趨勢。 實證結果顯示: 1.第一代類比式行動電話被數位式行動電話完全擴散的時間點,約在2001年發生。而CDMA技術完全替代TDMA的時間點約在1999年。 2. TDMA自1993年起專利數與專利成長率均大幅成長,到1997年在數量及成長率均大幅下降。CDMA則自1993年到1997年成長率呈上下震盪,在1997年專利數以5件微量超越TDMA。預估在2000年CDMA的專利數與成長率會大幅領先TDMA。 上述結果與目前國際電信聯盟 (ITU)所規劃的第三代行動通信系統標準IMT-2000中,各國所提出的提案趨勢大致相同,即CDMA技術將成為未來無線通信系統的主流。 | zh_TW |
dc.description.abstract | This research intends to identify the important factors affecting technology forecasting and to clarify the limitations to the inter-relationships among different forecasting methods. Criteria for selection of appropriate forecasting methods are based three factors, namely, the effectiveness of available data, the uncertainties of the technology and the development stages of the technology. This thesis applies the technology forecasting methods to predict the development trend of the wireless communications technologies. Major findings include the following. After reviewing the three dimensions of the twelve forecasting methods, the “growth curve” method is chosen to build the empirical model of technology forecasting to predict the timing at which the analog wireless communications technologies will be replaced by the digital communications technologies. This model is also used to estimate the timing at which the TDMA technology is replaced by the CDMA technology. An analysis on the patents of TDMA/CDMA technologies is also conducted. | en_US |
