摘  要
 ZigBee无线通信技术是一种新兴的短距离无线通信技术，具有低功耗、低速率、低时延等特性，具有强大的组网能力与超大的网络容量，可以广泛应用在消费电子品、家居与楼宇自动化、工业控制、医疗设备等领域。由于其独有的特性，ZigBee无线技术也是无线传感器网络的首选技术，具有广阔的发展前景。ZigBee协议标准采用开放系统接口(OSI)分层结构，其中物理层和媒体接入层由IEEE802.15.4工作小组制定，而网络层，安全层和应用框架层由zigBee联盟制定。
 本文首先介绍了ZigBee的发展前景与研究意义，并列举了一些ZigBee的应用例子与国内外对ZigBee的研究状况;接着根据IEEE802.15.4标准规范与ZigBee标准规范，简单扼要地阐述了ZigBee协议栈的物理层、媒体接入层、网络层、安全层和应用框架层等各层的功能以及各层间的接口。
 本文最后运用西安华凡科技有限公司的2.4GHz Zigbee SoC射频卡，进行点对点通讯实验（Light-Switch演示），以一个模块作为Switch，另一个模块作为Light，不停的按下Switch，Light就会交替闪烁，从而达到控制的效果。

Abstract
 ZigBee wireless technology is a new short-distance wireless communications technology，    and it is a low-power low speed and low latency wireless standard. ZigBee has strong network capability and large network capacity and it can be widely used in consumer electronics，home and building automation， industrial controls ，medical sensor application and other fields. For its special feature，ZigBee is the best choice for wireless sensor network.ZigBee stack architecture is based on the standard Open Systems Interconnection(OSI) seven一layer mode.The IEEE802.15.4 standard defines the two lower layers: the physical (PHY) layer and the medium access control (MAC) sub-layer. The ZigBee Alliance builds on this foundation by providing the network (NWK) layer and the framework for the application layer.
 First of all，the paper introduces the development and research significance of ZigBee,also lists some application examples of ZigBee and describes the development status of ZigBee in China and other countries. Then,the paper describes the functions of all layers and the interface of each layer shortly according to IEEE802.15.4 standard and ZigBee specification.
 Finally，using the 2.4GHz Zigbee SoC RF card which is made by XI’AN HUAFAN Science and Technology company to do the point-to-point communication experiment(Light-Switch demonstration),using one module as the “Switch”,, and the other module as the “Light”, and press the “Switch” continually, the “Light” will be flashing alternately to achieve the control effect..
