一种VOWLAN终端的设计及其实现

Designing and Realizing of One Type VOWLAN Terminal

VOWLAN是一种利用现有的WLAN网络实现无线的VOIP通话能力的技术。在成熟的WLAN和VOIP技术基础上,通过采用嵌入式微处理器[1]AT91M55800A实现VOWLAN移动终端的一种设计方案,并介绍了终端各模块软件和硬件具体的设计和实现,也阐述了终端在WLAN网络中实现语音通信过程;此外,将VOWLAN终端应用到一种有线和无线互联型网络的结构中,阐述了此终端在以太网和无线局域网通信过程。

VOWLAN, the convergence of VOIP and WLAN, realizes the data and voice in wired IP （Intemet Protocol） networks and wireless local area networks. A kind of embedded system is developed based on WLAN and VOIP in this paper, which contains the process of the VOWLAN terminal research and shows the communication of the procedure voice transmission through WLAN. In addition, This type of VOWLAN terminal is applied in the construct of wire and wireless networks. The communication of the terminal in the Ethemet with WLAN is also described.
