1. A wireless downhole information transfer system, comprising:
an elongated tubing having several tubing sections, comprising a first and a last end tubing section,
an information signal generator arranged on the outside of the elongated tubing and at or near the first end tubing section of the elongated tubing and designed as a torsional wave generator for transmission of a torsional wave information signal along the elongated tubing, wherein the information signal generator comprises at least one sound wave generator arranged transverse with respect to an elongation axis of the elongated tubing for generation of said torsional wave information signal, said torsional wave information signal emitted in a direction transverse to the elongation,
an information signal receiver arranged at or near the end tubing section of the elongated tubing, wherein the elongated tubing between the information signal generator and the information signal receiver constitutes a carrier for transmission of the torsional wave information signal between the information signal generator and the information signal receiver.
