| dc.description.abstract | WiMAX 系統在台灣已經積極的在建設，2009年4月已有業者在澎湖開台，2010年台中、台北相繼有業者開台，台灣六家WiMAX業者，只剩大眾電信尚未開台，其餘五家業者都已經開台，推出WiMAX上網服務，象徵台灣WiMAX服務正式邁入商業運轉期，基地台的建設也就相對重要，當進行WiMAX基地台的系統建置時，基地台的涵蓋範圍如何?用戶申請的上網服務，是不是真的能收的到訊號?連線的速度有多少?這都是WiMAX系統業者要考慮的問題。
本文就現有的WiMAX建設，根據基地台的系統參數，預估WiMAX站台的涵蓋範圍，再根據實際測量基地台涵蓋的距離，與預估的涵蓋範圍加以比較，找出適當的基地台涵蓋距離之鏈路預算，以提供WiMAX業者，建設基地台的參考。 本文根據實測RSSI值與模擬COST 231 Hata Model的RSSI值之關係，與兩篇IEEE Papers比較，驗證COST 231 Hata Model 是否適用於台灣WiMAX 2.5GHz頻段的環境。 本文透過實際站台的涵蓋測試，描繪出WiMAX基地台的涵蓋圖形，並做實際上傳、下載的測試，了解WiMAX基地台的真實連線連率。 | zh_TW |
| dc.description.abstract | WiMAX systems in Taiwan has been active in construction, in April 2009 has been began the WiMAX service in Penghu in 2010, Taichung, Taipei, there are companies begin one after another, There are six WiMAX operators in Taiwan,only First Internation telecom didn’t offer WiMAX services, and the others five operators have launched WiMAX Internet services, symbolize Taiwan's WiMAX service into commercial operation period. The construction of base stations also relatively important, while for WiMAX base stations and system implementation, how the base station coverage? User’s the application of Internet services, is really received the signal ? What’s the reality upload & download speed for user connecting ? This is WiMAX system operators must to consider.
This thesis base on the existed WiMAX networks , according to the base station system parameters, estimated coverage of WiMAX base station, then the base station based on the actual measurement of the coverage distance, and to compare the estimated coverage, find the appropriate base station covers the distance of the link budget , to provide the WiMAX operators a reference on set up base station. The RSSI value of the measured and simulated the RSSI value of COST 231 Hata Model of the relationship compared with two IEEE Papers ,verify whether COST 231 Hata Model is applicable to Taiwan's WiMAX 2.5GHz band environment. This thesis provide a practical test by describing a WiMAX base station graphic of coverage , and do the actual upload & download speed test, understand the WiMAX base station throughput. | en |
