摘　　要：无线数据是当前通信领域一大热门的话题,随着联通基于CDMA1XRTT网络的大规模建设和推广应用,移动网络的数据传输正逐渐变为现实。CDMA网络除了可提供清晰的话音外,还可提供最高153.6kb/s的数据传输速率,这个速率能使许多数据业务得到应用。但在实际网络中还存在一些环节制约了平均数据传输速率最大化。如何提高无线网络速率、网络吞吐量、减少传输时延,更好地发挥CDMA1X网络的无线数据优势是当前CDMA网络优化中的一个重点课题。本文从CDMA网络结构和无线数据传输原理着手,通过无线网络、分组网和业务应用层等多层次地优化,提高了网络数据传输性能、达到了优化网络数据传输速率的目的。It is known that wireless data is one of hot topics in the area of communication. With the development of Unicom CDMA 1XRTT Network, it may be realized that the data service transfer through CDMA 1XRTT Mobile Communication Network. In addition to provide clear voice, CDMA Network can also provide high data transmission speed of 153.6 kb/s.The speed is higher enough to provide much data service. But in the actual network, some factors restrict the average data transmission speed. So how to improve wireless data transmission rate and the network throughput,reduce transmission delay, and finally keep the superiority of CDMA 1X network′s higer wireless data transmission rate, is a key project of the CDMA Network Optimization Center. The thesis based on the theory of CDMA network structure and wireless data transmission, through optimizing wireless network,packed data service network and service application layer to improve the capability of data transmission and optimize the network.
