  • Transceiver
    Patent number: 6560274
    Abstract: A (mobile) transceiver can be switched into different equipment states, and is provided with an equipment state in which supplementary functions (appointment calendar, games, etc.)—which do not require any transmission via a radio interface of the transceiver—can be executed without any transmission of the transceiver via the radio interface. In particular, there is no transmission of a signal or organizational data which is normally automatically transmitted when a transceiver is activated or in a standby or a ready-to-receive state.
