900MHz无中心多信道选址通信系统的容量究竟有多大,对我国的蜂房公众网有无干扰?本系统内三阶互调干扰是否严重,会不会造成对控制信道阻塞?为了回答人们的疑问,本文对无中心组网的话务量、用户数与服务质量作了计算,并对三阶互调对蜂房公众网和本无中心网的干扰条件和概率作了分析,结论是该系统能够承担中等容量任务,对公众网不会造成干扰,只要从技术上和管理上采取措施,也不会对本网造成有害影响。这些理论分析也被计算机模拟和国内外组网实践所证实。
900MHz centerless multi-channel site-based communication system, how much capacity, the public network of our country has no interference? Third-order intermodulation interference in this system is serious, will not cause the control channel congestion? In order to answer people’s questions , This paper calculates the traffic, user number and service quality of the non-central network and analyzes the interference conditions and probabilities of the third-order intermodulation to the cellular public network and the non-central network. The conclusion is that the system can Undertake medium-capacity tasks, the public network will not cause interference, as long as the technical and management measures taken, it will not cause harmful effects Ben Wang. These theoretical analyzes have also been confirmed by computer simulation and network practice both at home and abroad.
