Pharmaceutical compounds having the general formula: . According to said method, a transmitter emits signals, a receiver receives signals emitted by the transmitter, positional andor movement-related data of the means of transport are determined, and the use of the means of transport is detected based on an evaluation of the change in intensity of successive signals received by the receiver as well as the positional andor movement-related data. In other cases, the mobile station determines an MCS based on channel quality measurements, and feeds back the MCS adaptation decision to the network. A message addressed to a tag routing address of the tag may be received, and a response to the message may be sent.
