Optimization Of CDMA Evdo Wireless Network Of Telecommunications Companies In Shuozhou

CDMA is a kind of advanced mobile telecommunication technology, which fulfill great capacity and quality、synthetical operation、soft switch and international ramble. It possesses lots of merits such as repellence of interference and attenuation of multiple paths. The security is also great trait of CDMA. CDMA is the main operation that China Unicorn extend.The progress of CDMA right result in the success of China Unicom, and the development of operation must depend on perfect network.The purpose of this task is to investigate the best methods that can optimize CDMA2000EVDO wireless network by collecting data of network which is in operation and analyzing the data in order to find the cause which influences the quality of the network. The advantage of CDMA is application of power control and soft switch, so they are usually the emphases during base station optimizing. On the other hand, data optimizing is also important and difficult.The paper is to identify problems in the network and give the network corrective measures through the analysis of CDMA EVDO systems, BSC resources, the BTS E1bandwidth occupancy rate, CE resources, physical layer service channel duty cycle, RLP maximum number of users and the call traffic. Using wireless network optimization technology means of the CE expansion, increasing the transmission link, and adjusting the parameters to stable operation of the network and have the technical indicators achieve the best value.
