Method for wirelessly transmitting data between a plurality of communication units arranged in a rotating component and rotating component
First Claim
1. A method for the wireless communication of data between at least one communication unit, which is arranged in or on a rotatable part and to which at least one sensor and/or actuator is respectively connected, and at least one base communication unit which is arranged in radio reception range outside of the rotatable part, comprising determination of frequency-dependent Doppler shifts for frequencies in the frequency spectrum on the basis of the speed of revolution of the rotatable part, transmission of the data using the ultrawideband radio transmission method (UWB) on a frequency spectrum of more than 500 MHz or a frequency bandwidth of more than 0.2 times an average transmission frequency, and compensation for the determined Doppler shifts in a received signal.

Abstract
A method for the wireless transmission of data between at least one communication unit (2) which is arranged in or on a rotatable part (1) and to which at least one sensor (S) and/or actuator is respectively connected, and at least one base communication unit (4) which is arranged in radio reception range outside of the rotatable part is described. Transmission of the data using the ultrawideband radio transmission method (UWB) on a frequency spectrum of more than 500 MHz or a frequency bandwidth of more than 0.2 times the average transmission frequency is proposed.
