A Design And Realization Of Wired/wireless Mixed Commanding Dispatcher's Communication System

Professional Mobile Radio (PMR) is an important part of wireless mobile communication system, it means that mobile communication system specializes in inside every department and the unit, offer service of commanding dispatcher's communication mainly, so called wireless dispatcher's communication system. Trunked mobile communication system is a advanced developing stage of Wireless dispatcher's communication system. The system is applied to every department of national economy, and play a very important role in the development of national economy,the stability of the society and the security of people's lives and properties. The text has introduced a scheme of wire /wireless mixed commanding dispatcher's communication system. With the wired dispatcher's communication regarded Digital Program-control Dispatcher's Exchange as the core, The scheme inserts Large –district Rule wireless dispatcher's communication system and other mobile communication equipments (The cordless telephone), forms a wired/wireless mixed commanding dispatcher's communication system. This system inserts PSTN' s public telephone network through the junction line, and realize the function that a reliable flexible conductor manage. This scheme has already been applied to the sledge slippery rail proving ground of rocket of China's Aviation Lifesaving Institute( 610) at present, while it bear various kinds of large-scaly test, no matter various kinds of weather, the topography and task of testing are required, it can guarantee the sledge slippery rail proving grounds of rocket's communication commanding dispatchers to be unblocked in the cover range of the system, and finish the communication between the test site user and local call user at the same time . In the actually use it indicates that this is a easy realizing Professional mobile radio scheme with good performance.
