Abstract

An apparatus is disclosed. The apparatus comprises a communication interface unit configured to receive reference biosignal data, and a wireless interface unit configured to receive a plurality of candidate biosignal transmissions from candidate biosignal transmitters. A comparison unit of the apparatus is configured to compare the reference biosignal data with the candidate biosignal transmissions, thus resulting in comparison data. The wireless interface unit is configured to execute a pairing protocol with a candidate biosignal transmitter of a candidate biosignal transmission by utilizing the comparison data.
