中文摘要：

无线传感器网络作为一种新兴的技术具有广泛的研究价值和实际应用价值。设计并实现了一个多频段的无线传感器网络实验平台。该平台包括2.4GHz和433MHz的两个子网。两个子网分别通过网关与PC机相连,PC机完成对不同子网的数据包分析和解包,并可对各子网下达指令。实验结果表明,该平台能够完成胜任一般实验的需求,对于理论研究和实际应用都具有十分重要的意义。

英文摘要：

As a new kind of technology wireless sensor networks has a wide range of research value and practical application value.Design and implement a multi-band experimental platform for wireless sensor networks.This platform includes 2.4GHz subnet and 433MHz subnet.The two subnets are connected to the PC through the gateway.And the PC would receive and process the messages and it may also inject commands to the subnet.Experimental results show that the platform is able to meet the needs of general experiment,and has great significance to theoretical research and practical applications.
