Device for common connecting operation antennas of mobile telephony base stations, with telecommunication reception devices, for use in radiointerference detection, is connected by inserting directional couplers (1,2,3), (4,5,6), (7,8,9), in the paths related to the radiofrequency reception, either between every two antenna duplexers (22), (23), or between transceiver units (24) and combiner units (25), being units of every radiosystem of the base stations. The device combines and amplifies signals coming from the antennas and passing through the directional couplers (1,2,3), (4,5,6), (7,8,9), by using appropriate radiofrequency combiners (10), (12), (14) and amplifiers (11), (13), (15), eventually terminating at an output of another combiner (16) to which a telecommunication reception device (26) is connected. By using wire-connected or wireless modems (27), (28), a computer (29) and the appropriate software, both the relays (P1,P2,P3), (P4,P5,P6), (P7,P8,P9), (P10), (P11), (P12) of every such device and the telecommunication reception device (26) are controlled remotely, for detection, monitoring, and demodulation of radiointerference generating signals, recording and documenting the relevant data and also determinating approximately the geographical origin thereof. |
