A torsion suspension includes two longitudinal control arms having front ends and rear ends in travel direction and a torsion axle extending transversely to and interconnecting the longitudinal control arms. A diversity controller compares qualities of signals received simultaneously from the different antennas during the selection mode, and controls the switch arrangement in the receiving mode, to use the better antenna. A description of management operations and corresponding timestamps are recorded to an operation log stored in a memory. The dipole portion has at least one dipole feeding port configured to couple the dipole portion of the multiple-element antenna to communications circuitry in the mobile communications device. The disclosure also claims a die, a functional element, and a component assembly comprising the functional element and a sheet metal part. Before a mobile station residing in a first ASN switches to a neighboring second ASN, an authentication process between the mobile station and the second ASN is implemented.
