隨著無線網路的蓬勃發展，擁有廣大使用者的IEEE 802.11(WLAN)，因為其傳輸距離及傳輸頻寬已漸漸無法滿足眾多服務的需求，因而誕生了下一個世代的無線網路通訊標準IEEE 802.16(WiMAX)。它具有下例特性︰(一)可同時提供不同的服務品質(Quality of Service)需求；(二)可提供高頻寬的傳輸速率；(三)涵蓋的範圍更廣；(四)建置與維修管理成本低；(五)具有最後一哩(The Last Mile)的特性。基於上述優良特性，本研究將探討以下兩部份︰(一)如何將無線網路IEEE 802.11與IEEE 802.16作異質性網域的整合；(二)設計出一套可以共同使用在IEEE 802.11與IEEE 802.16通訊協定上的服務品質機制，並達到以最少的頻寬滿足所有服務的期望。

Along with wireless network’s vigorous development, the transmission range and bandwidth of IEEE 802.11 (WLAN), which used to have a large number of users, is now becoming unable to meet the requirements of numerous services gradually. Therefore, the next-generation wireless network, IEEE 802.16 (WiMAX) was thus born. It has the following characteristics: (1) it can simultaneously provide different kinds of quality of service (QoS); (2) it can provide high bandwidth data rate; (3) it can cover a wider range of area; (4) the cost of establishment and management is low; (5) it has “the last mile” characteristics. Based on the above attractive characteristics, this paper discusses the following two issues: (1) how to integrate IEEE 802.16 with IEEE 802.11 to create an integrated heterogeneous network; (2) how to design a set of QoS mechanism for application in IEEE 802.16 and IEEE 802.11 integrated network to satisfy all service requirements by given the least bandwidth.
