摘要

現今的網路越來越盛行，從有線網路發展到無線網路，如今Wi-Fi的技術雖在生活上的應用已使用很久，但有幾點缺點還是一直無法突破，如傳輸距離只能限制在短距離內，而無法傳送較遠的地方，但Wi-MAX (Worldwide Interoperability for Microwave Access) 彌補了Wi-Fi的一些缺點，加上近年來VoIP (Voice over IP) 越來越受到注重，慢慢的取代了家用電話，透過網路的方式來撥打電話，節省電話費用，因此若將Wi-MAX與VoIP結合，不但傳輸速率足以比擬，傳輸品質也更適用於語音傳輸。
本文所探討的是將Wi-MAX的運作方式，套用在一般所使用的語音環境，在這模擬的環境下分析此系統可容納多少個使用者以及在網路中的效能結果。

Nowadays, the network prevails over the world, from wired networks to wireless ones. Although the Wi-Fi networks have used for a long period of time, some weaknesses still exist. For example, the usage is limited to very short distance. The Wi-MAX (Worldwide Interoperability for Microwave Access) may improve some weaknesses of Wi-Fi and can be viewed as a complementary system of Wi-Fi. Moreover, the VoIP (Voice over IP) is becoming a popular and will gradually replace the traditional telephone systems. As such, the VoIP system over Wi-MAX is desirable choice.
In this thesis discuss the usage of voice applications over Wi-MAX. We evaluate the system performance such as pachet dropping rate, channel throughput and mean delay by computer simulations.
