Method for testing a radiocommunications network, corresponding device and base station

A device for the testing of a radiocommunications network enabling the detection and elucidation of the nature of the interference between at least two transmitters, namely a mobile station sending useful signals towards a base station and at least one interference unit sending interference signals also towards the base station, wherein said device comprises:

• a first antenna and a second antenna each comprising an array of radiating elements distributed in a matrix arrangement on a support;
• downline from said first antenna, a first reception line comprising first reception means and, downline from said at least one second antenna, at least one second reception line distinct from said first reception line comprising second reception means;
• means for assigning said first reception line to the reception of first signals, in a first incoming direction;
• means for assigning said second reception line to the reception of second signals, in a second incoming direction;
• means for decoding the first signal received by the first reception line and the second signal received by the second reception line;
• reading means placed downline from said decoding means so as to read an identifier conveyed by the signals and distinctive to the transmitter that has sent said signals;
• decision-making means enabling, as a function of output signals from said decoding and reading means, to determine firstly which of said first and second signals are said interference signals and, secondly, the incoming direction of said interference signals or
• the identifier, if any, of said at least one interference unit sending said interference signals.
