Qiqihaer 3G Wireless Networks Planning

Mobile is one thing can not be forget for one person in his life. Since 1987, there is a rapid increase for the number of the mobile users. Along with the continuous development of modern communications technology, mobile communications system has obtained a rapid growth in recent years. Sine June 2003, the number of global mobil users had been 1300,000,000 and the occupation ratio more than 18%. It is more and more signaficiant that mobil alternating fixed and there in more than 100 countrys, the users of mobie are more than that of fixed. The mobil user in China is keeping increasing now, and in July 2001, the mobil users in China had overpassed that in USA and become the biggest mobil market in the world. Up to October 2003, the number of mobil users in China had overpassed 257,000,000 and the number of fixed users (255,000,000). Up to June 2004, the number of mobil users had overpasseded 300,000,000 and get to 300,599,000. The occupation ratio has approached 20&. On one hand, the capacity of mobile communications system have been expanding quickly and higher capacity, higher coverage, higher quality are the target of the system. On the other hand, the mobile communications system is moving to the stage of combining the data services, multimedia services and intelligent services. The transmitting rate of radio data will reach the speed of 2Mb/s. To fulfill the more bandwides requirements, HSDPA is build in the standerzine in 3GPP for WCDMA. It can reach the speed of 10Mb/s. The 3rd mobile communications can provide many high quality services and global no-seam covered. Users can roam globally and can get any kind of communications in any time anywhere by mini terminals. On the study of 3rd mobile communications, this paper identifies that WCDMA is the best choice of Qiqihaer city. After the works of driving test and data processes, the paper correct the model of Ericsson Urban and Ericsson 9999.After the theoretical analysis and calculation, the paper get the results that are suitable to Qiqihaer city's capacity and coverage Hereinafter, by using the software Tems Cell Planner Universal of Ericsson ,the paper compares the conclusions of theoretical analysis and computer simulation. Finally, the conclusions are that the WCDMA sites number is 67 in urban areas of 29km2,and the amounts are also perfect in the computer simulation study. The paper has the reliability in constructing operation of 3rd generation wireless network. It gives the solid foundation of next decision-making in network construction.
