Nanyang Telecom Of Cdma2000-evdo Wireless Network Planning And Implementation Of The Program

The 3G network of CDMA2000 mainly includes CDMA-lx and EVDO. There are two versions of EVDO which are RlsO and RevA. With the rapid development of EVDO RevA, EVDO RlsO has gradually been replaced by RevA, therefore the contents of this paper only refers to RevA. The carriers mostly prefer to build EVDO on basis of CDMA 1X network rather than merely build EVDO network, EVDO and CDMA IX network will coexistence in a long-term, therefore the radio network planning and implementation are based on these two kinds network.Through the comparison of 3G and 2G network, we propose a optimization plan of EVDO by taking Henan Nanyang as an example. In the paper, we sketch out the feature of CDMA2000 1x and EVDO RevA optimization, we also make some suggestions on radio network planning and implementation, including coverage planning, capacity planning, and key points of construction. Most importantly, we formulate the radio network optimization process and data analyzing process.This optimization project involved BSC1 and BSC2 which related to 299 a base station. Within the optimization project operated on the local CDMA network, we summarized a set of effective network optimization method through on-site evaluation and submitting optimization planning.We did some research on the process of EVDO network optimization basic on the implementation of network optimization, which means through the evaluation of the system's performance, we optimize the system, by reforming the system or adjusting the signaling, circuit and parameter of certain equipment, to provide better service. In the end of the article, we state some researches on throughput rate optimization and allocation algorithm of data services, the DT data and rate matching, which indicate the necessity of network optimization.
