Abstract:
A method for the testing of a radiocommunications network consisting in detecting and elucidating 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 said base station, wherein the method comprises the following steps:downline from first antenna, implementing a first reception line and, downline from at least one second antenna, implementing at least one second reception line, distinct from said first reception line, each antenna comprising an array of radiating elements distributed in a matrix arrangement on a support; assigning said first reception line to the reception of first signals, in a first incoming direction; assigning said at least one second reception line to the reception of second signals, in at least one second incoming direction; said first reception line trying to decode said first signals and said second reception line trying to decode said second signals and, if the decoding can be done, reads an identifier conveyed by the signals and distinctive to the transmitter that has sent the signals, so as to determine firstly which of said first and second signals are said interference signals and, so as to determine secondly, either the incoming direction of said interference signals or the identifier, if any, of said at least one interference unit sending said interference signals.
