In order to reduce the power consumed by mobile radio transmitting/receiving devices (PT1, PT2) and thus increase their maximum possible duration of operation, the device-specific transmitting power is automatically regulated depending on special information (FSW, A-CRC, X-CRC), such as field intensity values (FSW) and transmission error values (A-CRC, X-CRC), received and acquired by the mobile radio transmitting/receiving device. The mobile radio transmitting/receiving device (PT1, PT2) has for that purpose a sequential control circuit (RK), in which the value of the controlled variables (here the device-specific transmitting power) follows the changing value of the command variable (here the received and acquired special information).

Afin de réduire la puissance absorbée par des dispositifs (PT1, PT2) mobiles d'émission et de réception radiophoniques et d'augmenter ainsi leur durée maximale possible de fonctionnement, la puissance d'émission spécifique au dispositif est automatiquement réglée en fonction d'informations spéciales (FSW, A-CRC, X-CRC) reçues et saisies par les dispositifs mobiles d'émission et de réception radiophoniques, telles que des valeurs sur l'intensité du champ (FSW) et des valeurs sur les erreurs de transmission (A-CRC, X-CRC). Le dispositif mobile d'émission et de réception radiophonique (PT1, PT2) comprend à cet effet un circuit de régulation en cascade (RK) qui adapte la valeur des grandeurs réglées (dans ce cas, la puissance d'émission spécifique au dispositif) aux valeurs variables des grandeurs de commande (dans ce cas, les informations spéciales reçues et saisies par le dispositif).
