Abstract: The network enables data to be communicated by radio, in accordance with the Digital European Cordless Telecommunications (DECT) standard, between a plurality of user stations (T), through a central control device (C) . Each user station (T) comprises a data terminal (PC), a mobile radio module (MRM) and an adaptor device (LM) which acts as an interface between the data terminal (PC) and the mobile radio module (MRM). The central control device (C) comprises a microprocessor concentrator (MC) and a plurality of radio modules or bases (RB) connected to the microprocessor concentrator (MC) by connecting lines (L).
Abstract: A radiotransmission station transmits digital data at a predetermined rate to a receiving station. The receiving station is controlled by a timing circuit which recognizes a predetermined enabling code. The digital data is transmitted as bit sequences and each sequence contains a first group of bits for synchronizing the timing circuit and the transmission rate. This first group of bits is followed by a second group of bits which includes the enabling code. The recognition of the enabling code enables the reviewing station to receive and process the transmitted information. The enabling code is derived from a sequence of logical "1" and "0" bits and certain bits of the sequence are altered to form groups of three like bits (111,000). Each group of three bits has no more than two adjacent pairs of like and opposite bits (00,11).
