The Application And Optimize Way Of Data Service In CDMA2000

The mobile communication has rapidly developing in the current years. It came through the analogical and digital communication modes. In the latter, the most regular technologies are Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA). Although the launch of CDMA is late, it displays a powerful life-force.When the first CDMA system business running start in 1995, the some advantage of technology theoretic are proved in practice, it gained popularize and appliance quickly by north-America, south-America and Asia . CDMA is develop direction of mobile communicate technology. The phase of 2G, the CDMA extend type-IS95 with GSM are same in technology level , provide operation type approximately , but CDMA technology have unique characteristic, have salience in sound quality , call drop, radicalization and environment protect and so on . in phase of 2.5G ,CDMA20001X RTT have difference with GPRS in technology, the transmit rate higher than GPRS, more mature than GPRS in carry new operation type, CDMA can offer more new service type of high transmit rate. From CDMA 1.X transition to CDMA3.X more smoothness than from GPRS to WCDMA.This article from basic concept and integrate work actuality , expound the characteristic and any problem when maintenance the CDMA system in Unicom Co of HuLuDao , stress analyze especially the data transmit slowly ,analyze the problem appear in fact work and theory analyzed , discuss the choke point and bring forward the change project.
