Application of Embedded Linux in Wireless File Transfer System

摘要

A new design of wireless file transfer system is proposed in this paper.We develop a wireless file sending terminal based on wireless communication technology and computer science;design the hardware set of wireless file sending terminal by using embedded microprocessor and wireless communication module;build a embedded Linux operating system platform and transplant the PPP;and we develop the applications with multiprocess,design the CDMA wireless communication software with TCP/IP and PPP and do the debugging and test running.Improvement is made upon the existing wireless transfer module by optimizing it in line with wireless features and accelerating its transfer speed four times faster to implement wireless file transfer.
