A method for connecting a conductive metal strip, or tab, to a solar cell, which solar cell is provided with metal attachment points, in which a tab is placed at a respective attachment point, wherein the connection between the respective attachment point and the tab is realized by a non-contact connecting technique. A system transformation is obtained by selecting a weighting matrix that when linearly transforming a channel utilized for wireless communication, results in a particular transformed triangular matrix. This is advantageous in that the subjective perception of superimposition artifacts by a hearing device wearer is reduced. And to at least partially limit electromagnetic emissions from the respective network device interface element andor the respective remote device, each network device interface element includes a suppression assembly.
