For the past decade the technology improvement on the 802.11 based Wireless Local Area Network (WLAN) has become more mutual, therefore not only the speed and price giving it great attraction, the application and usage area have been upgrade from specific environment to internal enterprise networking and now heading to Public Wireless Local Area Network (PWLAN) development.You can notice the PWLAN exist in most public area like airport、hotel、coffee shop and fast food store.
Besides the traditional data exchange, the network usage has been used on other application, such as voice and video. All this application is not for the wired networking only, it also applied to the wireless networking. To process all the different characters information, we need to have reliable mechanism to ensure the quality of service.
Therefore the subject to discuss the real-time data exchange over wireless networking for multimedia application becomes more and more. This paper is meanly to discover the 801.11e, the MAC standard protocol over wireless networking, to give higher priority process the best efficiency of usage mapping and differential service level in the join of data flow. |
