隨著多媒體技術的極速發展，次世代無線網路日漸普及，然而也由於無線網路服務種類繁雜，各家基地台林立，造成傳輸系統複雜難以整合；又無線網路傳輸容易受到建築物遮蔽，使室內無線訊號的覆蓋率不佳，這些問題都日漸受到重視。本論文提出利用多服務光纖載無線通訊 (Radio over Fiber, RoF) 技術解決室內無線訊號覆蓋率不佳與多種無線網路服務並行所造成的傳輸系統複雜等問題。

透過功率預算分析，我們整理出各種不同傳輸系統架構的功率預算公式，並藉由這些公式探討於各類環境中所適合使用的傳輸系統架構。在實作方面，我們提出一個可透過頻帶分離器同時傳輸兩個不同頻帶訊號的多服務RoF的系統架構，並實際量測LTE訊號與WiMAX訊號經由此RoF系統傳輸所接收到的訊號品質與訊號互相干擾情形。我們也利用功率預算公式，分析此多服務RoF系統的效益與可行性，並進一步探討如何在台科大電資大樓架設此多服務RoF系統，使訊號足以覆蓋整棟大樓。

Due to the rapid development of wireless access networks, the network system design faces two major problems. One is the shadowing effect of building envelopes that limits the coverage of wireless networks, and the other is the complexity of transmitting system which is caused by the growing number of different wireless access network service providers. In order to solve these problems, we investigate a multi-service radio over fiber (RoF) architecture that can extend the network coverage and deliver multiple services.

In this thesis, a few power budget calculations have been used to discuss the lowest cost and the best energy saving transmission systems in different environments. In the experiments, we developed a RoF architecture to transmit two different frequency RF signals from WiMAX and LTE simultaneously through a band splitter which can split or combine the two signals. Also, the performance of RoF transmission and the interference between the two signals are measured. Then, the power budget equations are used to analyze the practicability of this two-service radio over fiber architecture in electrical engineering building (EE) of NTUST.
