Abstract (en)
[origin: DE19827028A1] According to the invention, a mobile radio device is provided for wireless data transmission according to a GFSK method, as performed, for instance, with DECT devices. The device has a receiver (6), a first measuring device (6) for error rate of the received data, in addition to a second measuring device (3) for field intensity (8) during data reception. An evaluation unit (6) processes the measured error rate and the measured field intensity. Depending on the measured error rate and the measured field intensity, a control unit (13) regulates the frequency sweep of the GSFK method that is used for wireless data transmission (15) by a transmitter (5) in the mobile radio device (15) with the purpose of optimizing transmission performance. In order to optimize transmission performance, a first table (12) and a second table (14) are provided in the evaluation unit (6), which reproduce the range that may be obtained or the interference immunity that may be obtained of the transmission (15) depending on the selected frequency sweep.
