Abstract: 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.
