Method of radio transmission of data, wherein the method comprises the following steps: sending the data in a standard-compliant telegram according to a defined standard by a radio transmitter for radio transmission, wherein the standard is defined according to a protocol for radio transmission including specifying of the telegrams, sending a further telegram by the radio transmitter, wherein the further telegram contains an error correction data set with error correction data for the data contained in the standard-compliant telegram, which error correction data allow error correction of the data in the event of transmission errors due to redundancy, receiving the data in the standard-compliant telegram by a radio receiver for radio transmission and detecting a transmission error in the received standard-compliant telegram by the radio receiver, wherein, in the event of a transmission error in the standard-compliant telegram, the further telegram is received and evaluated with the error correction data and the error correction is carried out by the radio receiver, wherein the further telegram is sent at a defined time interval after the standard-compliant telegram, wherein the further telegram is sent without a preamble and without a sync word, but after a transmission pause which is so short that the radio receiver does not lose bit synchronization during the transmission pause, wherein the short transmission pause is a maximum of 10 bit times and a bit time is defined as the time required for the transmission of a bit, and the further telegram is only received and evaluated if a transmission error was detected in the standard-compliant telegram. sending the data in a standard-compliant telegram according to a defined standard by a radio transmitter for radio transmission, wherein the standard is defined according to a protocol for radio transmission including specifying of the telegrams, sending a further telegram by the radio transmitter, wherein the further telegram contains an error correction data set with error correction data for the data contained in the standard-compliant telegram, which error correction data allow error correction of the data in the event of transmission errors due to redundancy, receiving the data in the standard-compliant telegram by a radio receiver for radio transmission and detecting a transmission error in the received standard-compliant telegram by the radio receiver, wherein, in the event of a transmission error in the standard-compliant telegram, the further telegram is received and evaluated with the error correction data and the error correction is carried out by the radio receiver, wherein the further telegram is sent at a defined time interval after the standard-compliant telegram, wherein the further telegram is sent without a preamble and without a sync word, but after a transmission pause which is so short that the radio receiver does not lose bit synchronization during the transmission pause, wherein the short transmission pause is a maximum of 10 bit times and a bit time is defined as the time required for the transmission of a bit, and the further telegram is only received and evaluated if a transmission error was detected in the standard-compliant telegram.
