FIELD: physics, communications. ^ SUBSTANCE: invention relates to a base station (BTS) for a cellular communication system which has user equipment on board an aircraft at a predefined altitude, and a ground-based network. The BTS is made as an on-board BTS which has a screening device which generates a first signal (S1) matched for screening a second signal (S2) from the ground-based network at a predefined altitude. The on-board BTS also has a signal generator which generates a third signal (S3) which is more powerful than the first signal (S1) and the second signal (S2), and can set up a communication line with user equipment through the third signal (S3). ^ EFFECT: no problems arise or minimal problems of cross-talk in the ground-based network arise when controlling connection/traffic towards user equipment and from the user equipment to the aircraft. ^ 16 cl, 6 dwg |
