1. A method comprising:
providing an antenna unit with a device-side signal interface and an antenna-side signal interface;
receiving a calibration signal with the device-side signal interface in a calibration process;
determining a signal strength of the calibration signal with a power detector;
comparing the determined signal strength with a reference signal strength; and
adjusting a gain factor of a gain controlling device such that the difference between the reference signal strength and a signal strength of a gain modified calibration signal is minimized, wherein the antenna unit is operated with the gain factor set in this way after the calibration process has ended and without transmitting the calibration signal or the gain modified calibration signal to an antenna connected to the antenna-side signal interface;
wherein the calibration process does not send the calibration signal or the gain modified calibration signal to an antenna connected to the antenna-side signal interface, thereby avoiding a transmission signal that could otherwise form an undesired interference signal emitted by the antenna that disturbs operation of other units.
