摘　　要： 无线射频(RF)是21世纪最有发展前途的信息技术之一,而CC1100正是其中一种单片UHF射频芯片。其低功耗、灵敏度高、链接性能好、工作稳定、外围元件简单的特点,得到了广泛地应用。介绍了一种以STC89C52单片机为控制核心,基于无线收发芯片CC1101的通信系统。通过对其的DATASHEET,工作原理以及工作方式进行了分析,设计了该系统的硬件电路并编写了CC1101芯片的通信软件。实现了点对点的无线数据通信,并增加了慢启动-拥塞避免功能和路由转发功能。使该无线数据传输系统的应用面增广,更加适合在不同突发状况下的无线数据传输。 Radio Frequency （RF） is the most promising technology in 21 century, and the CCll00 is one of the true UHF RF single chip. It was widely used with the advantage of low power consumption, high sensitivity, stable link performance, and simple external components. A wireless communication system with a single chip as the control center to STC89C52 is presented, and based on CC1100. Through the analysis of the datasheet, work- ing principles and working methods of the CC1100, designed the hardware of the system and the communications software of the CC1100 chip, and achieved a point to point wireless communications including simple route and slow-start-congestion-avoid algorithm. So that Simple Wireless Data Transmission System can be suitable for more unexpected situations.
