A radio network telephone system has a mobile phone module for a two-way voice communication with an external cell telephone, and analogue/digital conversion unit for converting the voice analogue signals into voice signals, a compression/decompressing unit for receiving and compressing digital signals, and a store for registering of programming data and temporary data. A CPU controls the operational sequence between these units. The telecommunication signals are activated by the radio-telephone module such that the embedded CPU processes and controls the voice (speech) information.
