從台灣行動通信網路的發展技術而言,在近年來,可謂一日千里,最早從1997年開放第一張民營的GSM執照(2G網路),將台灣的行動通信網路由類比式朝向數位式世代的發展。接著交通部電信總局(現為國家通訊傳播委員會)於2002年,首次以多回合競拍制度,發放了以W-CDMA為主的第三代行動通信網路(3G網路),W-CDMA也由於採用寬頻無線接取(Radio Access)技術,因而產生了重大的變革,使得在數據服務的效能上獲得了極大的提升。
在短短五年後的2007年7月,政府又發放了另一無線寬頻接取技術Wi-MAX的執照,如此快速的進展,不僅使台灣的通信領域已達到世界級的地位,更奠定了未來對數位匯流Fixed Mobile Convergence (FMC)的重要基礎建設。本論文將以3G及3.5G實際網路為研究範圍,依據場測儀器之量測及系統網路所產生之報表,再加以 Key Performance Index (KPI)之佐證,以達優化網路之目的。
From wireless mobile technology point of view, it makes progress day by day at a tremendous pace in Taiwan telecommunication market. In 1997, the first GSM licence is released by government.The licence migrated the mobile system from analog to digital generation developement system. In 2002, the Directorate General of Telecommunication (DGT) released the third generation telecommunication system by multi-round auction for the frist time. Therefore, the Wide band Code Division Multiple Access (W-CDMA) based on the third generation system has been made a huge innovations on radio access technology, which improved the data service ability and performance.
The Wi-MAX licence is released in July 2007. The fast progress not only makes the mobile tochnology to the top level in the world but also be the important infrastructure of the Fixed Mobile Convergence (FMC) in the future. This thesis adopts the real network configurations as the research scope. According to the field measured instrumentation and the system network report, it achieves the optimiztion for the High Speed Downlink Packet Access (HSDPA) network by using key performace index.
