Recent years, wireless communication technology has got swift progress, the application of wireless communication technology are more widespread. With the rapid development of RF and microwave devices; the portable devices as the core of microprocessor are not only satisfied with calculation of the daily and event processing function, more often, these devices needed to communicate data with other e-quipments for transferring and exchanging. Therefore, several usual portable wireless transmissions are introduced in this article; and the design of wireless data transmission system based on nRF24l101 is described in detailed.%近年来,无线通信技术获得了飞速发展,应用范围也越来越广泛；随着射频和微波器件日新月异的发展,以微处理器为核心的便携式设备已经不仅仅满足于日常的计算和事件的处理功能,更多的时候,这些设备需要和其他的设备进行通信,进行数据的传输与交换；因此文章介绍了常用的几种便携式无线传输方式,并详细描述了一种基于无线数传模块nRF24L01的无线数据传输系统的总体方案设计.
