Method for communication between in each case at least two communication terminal devices (16, 18, 20, 22, 24, 26) that are connected to a respective one of at least two at least partly inductively and/or capacitively coupled communication lines (12, 14), wherein a communication protocol is utilised for communication over the respective one of the at least two communication lines (12, 14), and the communication protocol controls transmitting and receiving of communication signals of the respective ones of the at least two communication terminal devices (16, 18, 20, 22, 24, 26), for which purpose signal carriers are utilised, wherein on the transmission side, on a first of the at least two communication lines, a transmission power of the signal carriers is set up and on the receiving side, on a second of the at least two communication lines, a receiving sensitivity to these signal carriers is set up such that on the receiving side, in relation to the second of the at least two communication lines, a receiving signal strength of the signal carriers of the first of the at least two communication lines is smaller than a predetermined comparison value, characterised in that the receiving signal strength is a measured value of a respective receiving device of the respective communication terminal device, the receiving signal strength can be utilised to determine a variable that makes it possible to adjust the transmission power and/or receiving sensitivity, wherein to this end the receiving signal strength is compared with the predetermined comparison value, wherein the predetermined comparison value is selected such that communication over the second of the at least two communication lines (12, 14) can proceed substantially undisrupted by the signal carriers on the first of the at least two communication lines (12, 14), to this end the comparison value is predetermined such that, over the second of the at least two communication lines (12, 14), by demodulating the respective ones of the signal carriers, the communication signals transmitted with these signal carriers over the second of the at least two communication lines (12, 14) are determined to be undisrupted. wherein a communication protocol is utilised for communication over the respective one of the at least two communication lines (12, 14), and the communication protocol controls transmitting and receiving of communication signals of the respective ones of the at least two communication terminal devices (16, 18, 20, 22, 24, 26), for which purpose signal carriers are utilised, wherein on the transmission side, on a first of the at least two communication lines, a transmission power of the signal carriers is set up and on the receiving side, on a second of the at least two communication lines, a receiving sensitivity to these signal carriers is set up such that on the receiving side, in relation to the second of the at least two communication lines, a receiving signal strength of the signal carriers of the first of the at least two communication lines is smaller than a predetermined comparison value, characterised in that the receiving signal strength is a measured value of a respective receiving device of the respective communication terminal device, the receiving signal strength can be utilised to determine a variable that makes it possible to adjust the transmission power and/or receiving sensitivity, wherein to this end the receiving signal strength is compared with the predetermined comparison value, wherein the predetermined comparison value is selected such that communication over the second of the at least two communication lines (12, 14) can proceed substantially undisrupted by the signal carriers on the first of the at least two communication lines (12, 14), to this end the comparison value is predetermined such that, over the second of the at least two communication lines (12, 14), by demodulating the respective ones of the signal carriers, the communication signals transmitted with these signal carriers over the second of the at least two communication lines (12, 14) are determined to be undisrupted.
