摘要

近年來全球行動通訊技術隨著行動上網無線高速下載的需求方向發展。因此第三代行動通訊系統發展出增強下載傳輸速率的HSDPA技術（簡稱3.5G），從技術層面來看，HSDPA技術是在3G網絡基礎上針對數據下載服務的增強技術，這與EDGE作為GSM/GPRS增強版本類似，3.5G理論上能夠提供最大14.4 Mbps的傳輸速率，足以滿足行動上網服務的需求。 對國內業者而言，3.5G網路是由既有的3G網路系統升級而來，只需在3G網路架構中增加部份的硬體設備及將系統軟體升級，即可提供使用者3.5G網路服務的功能。 我國電信業者於2005年第三季開放WCDMA（3G）網路，於2006年9月陸續提供HSDPA（3.5G）網路。初期國內電信業者都在人口集中的都會區建置3.5G 網路，目前提供給使用者最大3.6Mbps的傳輸速率，並且隨著用戶數成長逐漸擴大3.5G網路服務範圍到次都會區。 本論文主要是實際量測我國四家電信業者的3.5G網路效能，說明目前四家電信業者的3.5G網路佈建情形及比較各家電信業者3.5G網路效能及差異分析。最後也建議未來當各家電信業者升級到7.2Mbps或14.4Mbps後可再次量測行動上網實際效能。

Due to higher, and more demand for wireless high speed download from mobile users, the global mobile communication technology has rapidly developed in this field recent years. Basically, the enhancement downloads transmits rate HSDPA technology (i.e. 3.5G) is developed above the 3rd generation mobile communication system. From the aspect of technicality, HSDPA is part of data downloading service enhancement technology under the 3G network platform, which is similar to EDGE performs as to the enhancement version of the GSM/GPRS. Theoretically, 3.5G can provide up to 14.4 Mbps transmit rate and is sufficient to satisfy the demands for mobile wireless internet.
From domestic mobile communication operator’s point of view, 3.5G network is simply an upgrade version of 3G network. In order to enhance the mobile wireless internet service, all it needs is to install the additional hardware in current system, and upgrade the software.
In Taiwan, the mobile communication operators have started their 3G network back to Q3 of 2005, and 3.5G network in September, 2006. At the beginning stage of 3.5G service, domestic operators focused on the users located in major metropolitan area, and provided up to 3.6Mbps transmit rate. Strategically, as the users increase, the service will also expand to rest of the rural regions gradually.
The focus of this thesis is to, through operators’ actual data collected, and surveyed, analyze the relation between the establishments of, and the performance of wireless internet service for the four major mobile telecommunication operators in Taiwan. In my conclusion, might do site survey by operator once again when migrating to 7.2 Mbps or 14.4 Mbps is in progress.
