Embodiment Construction
[0028] Figure 1a The variation of the rechargeable battery voltage as a function of time is shown, which is manifested during operation of a mobile communication transmitting device according to the prior art. Starting from the maximum voltage U_nenn, the rechargeable battery voltage drops over time, even without signaling, as shown in variation segment 1. If a signal is sent, a voltage disturbance ΔU1 occurs as explained at the outset. This voltage disturbance ΔU1 is associated with a specific transmit power P. If the rechargeable battery voltage reaches a predetermined voltage value U_nenn, eg given as U_nenn×x * , where the factor x=0.85 or 0.9, the transmit power P is reduced to P_reduc_spec, which results in a reduced voltage disturbance ΔU2. After that, the voltage disturbance ΔU2 remains constant. If the operating voltage during transmission, ie the rechargeable battery voltage after deducting the voltage disturbance ΔU2, is lower than the predetermined switch-off v...
