基于SIP的VOWLAN的研究和设计

Research and Design of Wireless VOWLAN based on SIP

VOWLAN是基于WLAN(无线局域网)的语音技术,是VOIP技术和WLAN的结合。终端选择Maxim/Dallas的DS80C400作为网络处理器,Audio Codes公司的AC48801作为语音处理器芯片。设计中的无线网络选择的RF收发芯片是Maxim公司的Max2830,该芯片是完整的RF前端方案,符合WLANIEEESM802.11b/g标准,它集成了实现RF收发器功能所需的全部电路。在软件设计方面,采用OSIP协议栈来实现会话的控制。

Voice over WLAN （Wireless Local area Network） is a technique of voice that is based on VOIP （Voice over Internet Protocol） technique and combination of WLAN. The network processor chosen is DS80C400 of Maxim/Dallas. As the DSP chips are widely used in audio treatment, the Audio processor chip chosen is AC48801 of Audio Codes Company.In this design,softw RF transceiver is Max2830 of Maxim Company, which completely incorporates all required to implement the RF transceiver function and conforms to the standard of WLAN IEEESM 802. 11b/g. In Softw are design, OSIP is used to control the dialogs.
