摘　　要：文中基于GPRS原理实现了静态图像的无线传输。重点介绍了利用PPP实现无线连接,从而实现无线传输;静态图像的JPEG压缩,有效降低了图像数据的信息量;利用SMTP协议实现邮件远距离Internet传输等。经检验,在实时性要求不高的应用场合,可以达到平均10s内传输一幅图像,具有一定的应用价值。Based on the principle of GPRS, realizes the wireless transmission of the static picture. Emphasis on wireless connection with PPP protocol which is used to transmit picture wirelessly,JPEG compression of static picture to reduce the size of information and dectronic email transmission with the protocol of SMTP. It has been proved that the system can be applied without requirement of strong real time,which can transmit one picture in 10 seconds.

关 键 词：通用分组无线业务 JPEG压缩 简单邮件传输协议 点对点协议
