  • Decentralized and synchronous data transmission process and network
    Patent number: 4930124
    Abstract: A process and network are provided for data transmission between a plurality of transmitting/receiving stations, called participants. The network is synchronous and decentralized. The connections between stations are omnidirectional in nature and the communications take place at the same frequency in accordance with a time multiplexing principle. Each of the different participants have one or more predefined transmission times towards one or more participants, also predefined, all of which is within a cycle.
