Apparatus and method for determining power parameters of at least one radio system arranged in or on a vehicle

A method for determining power parameters of at least one radio system of a vehicle, comprising:

• simulating a base station being via a base station emulator and a simulation antenna comprising at least three antennas;
• receiving electromagnetic radiation at angular positions via the simulation antenna, wherein the at least three antennas are arranged around a rotation axis of a rotatable platform to provide substantially continuous communication coverage with the at least one radio system across a full rotation of the vehicle, thereby minimizing signal shading caused by the vehicle's structure;
• and
• determining, via at least one testing unit coupled to at least one testing antenna, at least one power parameter of the at least one radio system as a function of a rotation angle of the vehicle.

An apparatus for determining power parameters of at least one radio system of a vehicle, comprising:

• a rotatable platform for receiving and rotating the vehicle;
• a simulation antenna comprising at least three antennas;
• a base station emulator coupled to the simulation antenna;
• at least one testing antenna configured to detect electromagnetic radiation from the at least one radio system;
• and
• at least one testing unit, connected to the at least one testing antenna and/or to the simulation antenna, the at least one testing unit being configured to determine at least one power parameter of the at least one radio system as a function of a rotation angle of the vehicle,
• wherein the at least three antennas are arranged around a rotation axis of the rotatable platform to provide communication coverage with the at least one radio system across a full rotation of the vehicle, thereby minimizing signal shading caused by the vehicle's structure.
