1. A system for emulating radio frequency channels, the system comprising:
an input device for inputting a channel scenario,
a channel coordinator device being in connection with the input device, and
at least two channel emulator devices each being in connection with the channel coordinator device and for outputting a corresponding radio frequency signal to emulate the channel scenario,
wherein the channel coordinator device is configured to control each of the at least two channel emulator devices on the basis of the channel scenario and geometrical information with respect to the at least two channel emulator devices,
wherein the channel scenario comprises or is at least one of a communication scenario, especially a communication link scenario, a radar scenario, a traffic scenario, or any combination thereof, and
wherein the geometrical information comprises or is an absolute position of at least a part of the at least two channel emulator devices and/or a relative position regarding at least a part of the at least two channel emulator devices with respect to each other.
