Abstract


At present , mobile phones have been one of the objects indispensable in people's daily life . The end of 2007 , the global mobile users has nearly 30 million and 430 million CDMA users , China is the fastest growing CDMA , one of the most active countries . This paper comparative analysis of the characteristics of the three main wireless technology of the third generation mobile communication based on the Zhengzhou geographical environment and administrative planning , virtual carrier networks development status and network evolution strategy to code division multiple access technology ( CDMA ) as the object of study of network development goals and this article . Based on the typical environment of the city of Zhengzhou road test , drive test data analysis and processing , covering the propagation model has been amended ; Then , using purely theoretical calculations , on the part of the CDMA wireless network specific capacity estimates , coverage determine the number of sites calculation work . Draw theoretical results , the use of Huawei ( Huawei Technologies Co. , Ltd. ) network planning software U - Net the results of a computer simulation study , the design system on the geographic information system coverage and pilot interference , a certain degree of simulation studies the results of the theoretical calculations . The theoretical concluded by the link budget calculations , to meet the requirements in the forward rate 307.2 kbps data services in the urban area of 212.4 square kilometers within the CDMA2000 1x EV - DO Rev.A base station number 192 ; Zhengzhou City , the Telecom plans to the existing 1 1X 170 sites the DORA computer simulation, can be found and can basically meet continuous coverage to 307.2 kbps . This paper presents preliminary ideas for future wireless network development , and provides a basis for further construction decisions .
