摘 要:DECT微蜂窝数字移动通信是程控交换机功能的延伸和扩展,目前在通信比较先进的欧、亚国家和地区得到了广泛应用。DECT系统具有灵活的接口,可在不同业务和不同用户之间进行频率分配,能最大限度地利用频率资源。DECT系统因其功能优异,在设计和安装等方面投资少,因此符合管道通信专网干线长、分散和容量少的特点。在管理基地、输油公司和各泵站采用DECT系统,可以形成管道通信专网的移动通信体系,提高办公效率。个人化、智能化和宽带化的综合业务数字网是管道移动通信的努力方向。DECT micro-cellular digital mobile communication,which is nowadays widely used in the districs and countries in Europe and Asia,is extrending and expanding the scope of work based on the programmed control exchange. Having a smart interface and distributing the frequency between different services as well as defferent users,the DECT system is capable of making use of the frequency resources to the maximum. Because of these functions, the low investment and cost in design and installation can meet the needs of the private pipeline communication network with long trunk,scatter and low capacity. Relying on the DECT systems'adopted in the administrative headquaters, transportation companies and pump stations,the mobile communication system of the private pipeline communication network can be established to enhance work efficiency. The personal,intelligent and wideband integrated sevice digital network are a development trend of the mobile communication of the pipeline.
