Data network for a vehicle combination

A method of operating a vehicle network installed in a vehicle, the method comprising:

• detecting that the vehicle is being or has been coupled to a further vehicle to form a vehicle combination, wherein there is a solid connection between the vehicle and said further vehicle;
• establishing a communication link from an inter-vehicle transceiver of the vehicle network to a corresponding inter-vehicle transceiver of a vehicle network in said further vehicle including generating a radio beam connecting the two transceivers;
• and
• maintaining the communication link while performing beam adaptation of the radio beam, including one or more of:
• a) performing a radio measurement aiming to localize the corresponding inter-vehicle transceiver and guiding the beam adaptation based thereon,
• b) measuring or estimating an articulation angle of the vehicle combination and guiding the beam adaptation based thereon.
