| Summary: | 碩士 === 國立臺北科技大學 === 電子工程系研究所 === 103 === As the huge progress of modern technology and the prevalence of personal electronic devices, each person have more than one laptop or personal digital assistant devices. Therefore, the requirement of the wireless internet increases as well. IEEE802.11 Wireless Location Area Network (WLAN) resolves the problem of constructing wires, and also provides internet service while users are moving. In order to deal with the requirement of a large number of data transmissions, WLAN standard has been constantly updated and modified, the latest specification is IEEE802.11 ac.
To increases throughput and transfer rate, IEEE modifies IEEE802.11n and defines IEEE802.11ac, known as Very High Throughput (VHT) which support some new features of MAC layer. This thesis will compare basic channel access method and QoS channel access method of IEEE802.11ac MAC layer with IEEE802.11e MAC layer. In addition, this thesis will also illustrate Wireless Mesh Network (WMN) channel access method which was not mentioned in the older IEEE802.11e MAC layer, and describe all the updated information.
