摘　　要：用Infineon公司的MIPS架构处理器ADM5120设计并实现了一个无线VoIP系统。从硬件和软件两个方面进行系统设计:首先对系统硬件三大主要模块即:ADM5120主处理器、VINETIC语音模块、存储模块分别进行了研讨;接着描述了如何在无线局域网内实现UDP方式点对点通讯和广播通讯。无线VoIP系统实现后经现场测试证明其性能可靠,价格低廉,具有广阔的应用前景。A description of the design and implementation of a wireless VolP system based on the ADM5120, which is MIPS processor of Infineon firm are proposed. The system is designed from both hardware and software views：Firstly,it discusses three main modules of the hardware system： ADM5120 host processor, VINETIC voice module and memory module. Secondly , it describes how to implement the UDP point to point communication and broadcasting communication in the wireless local network. After the field tests,the wireless VoIP system is proved to be reliable and inexpensive,and it has a good prospect of application.
