First Claim
Patent Images
1. A method for synchronization of network devices in a network, comprising:
- transmitting by at least one synchronizer, for a synchronized communication protocol based on time slots used for each network device for wireless data transmission by a transmitting and/or receiving unit, synchronization data with at least one synchronization signal, the synchronization data being received for each network device by a low-energy receiver having a lower energy requirement than the transmitting and/or receiving unit, and at least two bits are used for each synchronization signal.

Abstract
A synchronized communication protocol based on time slots is used for wireless data transmission. Synchronization data are received for each network device by an additional receiver which has a lower energy requirement in comparison with the transmitting and/or receiving unit. To specify an energy-efficient and, at the same time, robust solution to the synchronization, at least two bits are used for each synchronization signal, as a result of which the synchronization signals can be distinguished from, e.g., interferences or the susceptibility to interference can at least be distinctly reduced.

19. A synchronizer for wireless data transmission with a first transmitting and/or receiving unit using a synchronized communication protocol based on time slots by transmitting synchronization data from the synchronizer to a low energy receiver, having a lower energy requirement than the first transmitting and/or receiving unit, which receives and evaluates the synchronization data, the synchronizer comprising:
at least one transmitter transmitting the synchronization data with at least one synchronization signal, each synchronization signal having at least two bits. - View Dependent Claims (20, 21, 22)
