Method for geographic-based radiofrequency band selection

1) A method for data communication of a mobile device on a local area network, having a mobile device communication system, on an authorized radiofrequency band;

• the method comprising the following steps:
• determining a current data communication mode, said current data communication mode defining at least a radiofrequency band for communicating data;
• said determination of said data communication mode being performed using:
• a) a piece of geographical localization information obtained from a mobile communication network or a satellite-based positioning system;
• or
• b) a data communication mode obtained from a data frame exchange on said local area network;
• if the determination step is successful:
• enabling a data communication state of the mobile device wherein use of a radiofrequency band defined on the basis of said current data communication mode for data communication between the mobile device and the local area network is allowed;
• or,
• if the determination step is not successful such that no valid data communication mode can be determined:
• entering a silent state;
• and
• entering a sniffer mode.
