CENTRAL BUFFER COUPLER, SIGNAL TRANSCEIVER, VEHICLE MEMBER AND COMPUTER-IMPLEMENTED METHOD

A central buffer coupler has a first coupling head adapted to be mounted on a first vehicle member of a multi-member vehicle. The first coupling head contains a first signal transceiver (100) for communicating with a second signal transceiver (200) on a second coupling head mounted on a second vehicle member of the multi-member vehicle. When the first and second coupling heads are mechanically interconnected, the first and second signal transceivers (100; 200) are positioned facing one another in a physically matching manner, such that respective microwave transmitters (111, 211) and receivers (121, 221) therein face one another in an interface-module-pair (151, 251) with a first waveguide transmitter antenna (131) of a first microwave transmitter (111) in the first signal transceiver (100) physically matching a second waveguide receiver antenna (232) presumed to be communicatively connected to a second microwave receiver (221) in the second signal transceiver (200). Analogously, a first waveguide receiver antenna (132) of a first microwave receiver (121) in the first signal transceiver (100) physically matches a second waveguide transmitter antenna (231) presumed to be communicatively connected to a second microwave transmitter (211) in the at least one second signal transceiver (200).
