<p>The method involves passively listening in to a data connection established between a radio device and the mobile radio network with the test device, at least partly detecting and evaluating the information signals forming the basis of the communication using the test device and calibrating a reference frequency unit associated with the test device based on the evaluation. Independent claims are also included for the following: a test device for a radio device in a mobile network, e.g. a mobile telephone, and the use of radio device for frequency calibration of a test device.</p> |
