Abstract:
1. A method of detecting interfering technologies, the method being performed by a device, the device comprising a transceiver, the transceiver being adapted to employ a first wireless radio access technology, the method comprising: scanning a first plurality of frequency channels provided by the first wireless radio access technology for radio signals of a first interfering technology, the first plurality of frequency channels relating to frequency channels provided by the first wireless radio access technology in which radio signals of the first interfering technology being expected; detecting in each frequency channel of the first plurality of frequency channels the presence of a radio signal by measuring a first signal strength of the radio signal; identifying the first interfering technology as source of the detected radio signals, if for a preset number of frequency channels of the first plurality of frequency channels the first signal strength of a radio signal is detected, or scanning a second plurality of frequency channels provided by the first wireless radio access technology for radio signals of a second interfering technology if the preset number of frequency channels will not be reached during the scanning for the first interfering technology; determining for each frequency channel of the first plurality of frequency channels a number of detections, wherein the number of detections relates to the number of times a radio signal is detected in the corresponding frequency channel, determining the number of frequency channels of the first plurality of frequency channels for which the number of detections exceeds an expected number of detections, wherein the expected number of detections is specified for the first interfering technology, wherein the number of frequency channels for which the number of detections exceeds the expected number of detections provides an indication for the presence of at least a second interfering technology.
