1. An apparatus for a transceiver system included in a transportation vehicle, the apparatus comprising:
- a first communications module for communication in a first mobile radio system; and
a second communications module for communication in a second mobile radio system anda control module that adapts a transmission power level used in the first mobile radio system based on activity of the second communications module in the second mobile radio system to reduce interference arising from intermodulation of transmission frequencies used by the first and second communications module by facilitating dynamic adaptation of the transmission power level used in the first mobile radio system,wherein the activity of the second communications module corresponds to the use of a defined frequency band for communication that is different than a frequency band used by the first communications module,wherein the control module determines an expected intermodulation signal based on information about communication of the first communications module and the second communications module,wherein the expected intermodulation signal is indicative of one or more intermodulation products resulting from interference between communication of the first communications module and communication of the second communications module, andwherein the dynamic adaptation of the transmission power level used in first mobile radio system is performed based on the intermodulation signal in response to determination that intermodulation effects are expected based on relative location of the frequency bands for communication by the first and second communications modules.
