The invention pertains to a sliding door system with at least one automatically driven sliding leaf, which is guided on a traveling carriage and a support profile, where the drive and a runway rail are mounted in a housing above the sliding leaf, and where the sliding leaf can be swung open if necessary in the outward direction around a vertical axis. Measured RF channel characteristics for wireless devices are compared against the performance lookup tables to determine the sent of lookup tables that most closely match the measured RF channel characteristics. Together the first and second driving axle shafts define an axis of rotation about which the first and second wheel hubs rotate. A generator can be rotatably coupled to the first drive wheel. Each return device is able to release that energy to the corresponding hitching pin by returning the hitching pin toward the first position.
