Abstract: In order to develop an electronic communication system (100; 100?), designed for a progressive movement means, having at least one base station (10) and having at least one carrier station (60) such that the possible uses of this communication system (100; 100?) can also be extended to other important areas of use of a progressive movement means, it is proposed that the carrier station (60) be designed as in each case at least one sensor unit, which is assigned to at least one wheel or tire (90) of the progressive movement means and—which is designed to detect and/or determine at least one characteristic parameter of the wheel or tire (90), such as for example the air pressure and/or the temperature and/or the wear of the wheel or tire (90).
