Central buffer coupler, signal transceiver, vehicle member and computer-implemented method

A central buffer coupler (600) for a multi-member vehicle, which central buffer coupler (600) comprises:

• a first coupling head (610) adapted to be mounted on a first vehicle member of the multimember vehicle, which first coupling head (610) comprises at least one first signal transceiver (100) and a coupling element (611) configured to connect mechanically to a counter-coupling element of a second coupling head mounted on a second vehicle member of the multi-member vehicle, which second coupling head is presumed to comprise at least one second signal transceiver (200) arranged such that the at least one first and second signal transceivers (100;
• 200) are positioned facing one another in a physically matching manner when the coupling element (611) is mechanically connected to the counter-coupling element,
• wherein the at least one first signal transceiver (100) comprises at least one microwave transmitter (111, 112) and at least one microwave receiver (121, 122), which, when the coupling element (611) is mechanically connected to the counter-coupling element are arranged such that in at least one first interface-module-pair (151, 251;
• 152, 252):
• at least one first waveguide transmitter antenna (131, 141) of at least one first microwave transmitter (111, 112) of the at least one first signal transceiver (100) physically matches at least one second waveguide receiver antenna (232, 242) presumed to be communicatively connected to at least one second microwave receiver (221, 222) of the at least one second signal transceiver (200), and
• at least one first waveguide receiver antenna (132, 142) of at least one first microwave receiver (121, 122) of the at least one first signal transceiver (100) physically matches at least one second waveguide transmitter antenna (231, 241) presumed to be communicatively connected to at least one second microwave transmitter (211, 212) of the at least one second signal transceiver (200).
