      A comment has been posted on Pubpeer on this publication in PLoS One. The authors use a transmitter out of its technical specifications, i.e. the transmitter bandwidth is 1-50Hz, the nominal sampling rate 250 Hz. Theoretically, frequency reconstruction is possible up to 125 Hz (see Nyquist-Shannon sampling limit). However, the authors analyze up to 500Hz. This is not possible and not correct.
