The CDMA450 Wireless Access Systems Planning And The Application In The Rural

Uses CDMA technology 450MHZ the CDMA wireless access system, namely CDMA450 wireless access system, because has the frequency lowly,covers broadly, in room penetrating power strong, the capacity is big,invests and so on the characteristic lowly, is the farmer communication system best choice. Therefore, the CDMA450 wireless access system obtained the widespread application in China's rural communication, for realizes our country' all rural to make the telephone the goal, has provided the reliable technical guarantee.This article was divided six chapters to the CDMA450 wireless access system composition, the plan principle and the practical application and so on the related question has carried on the discussion.First,this article from turns on the net the concept and the principle embarks, thoroughly introduced the CDMA450 wireless access system composition, the principle of work and the network way, the main connection and so on, and has analyzed the characteristic and the superiority which 450MHZ the CDMA wireless access system has.Next,this article has carried on the key discussion to the CDMA450 wireless access system plan method. Introduces from the CDMA450 wireless access system plan characteristic starts, in detail introduced the plan two main flows pre- plan and the detailed plan. And introduced in the plan flow cover plan, the capacity planning and the system simulation with emphasis and so on.Then, this article system has carried on the detailed introduction to China for company CDMA450 the wireless access system product RASYS, to the RASYS system technical characteristic and the superiority, the support service, the network way has carried on the introduction. Finally two chapters, this article introduced with emphasis the Guangxi telecommunication village passes the actual problem and the project which project RASYS in the construction plan, the construction process solves clears the movement situation. To the engineering construction background, the engineering construction goal and the plan shaping, the question solution and so on has made the detailed introduction, and carried on to the project economy and the social efficiency had expounded.
