Patent ID: 8140049

Claim:
Method for operating a communication arrangement, said communication arrangement comprising a plurality of devices, wherein for each of said devices a presence of interferences caused by operating other devices, caused by a communication line used for own communication and/or from operating radio services is monitored and in the case that interferences from said operating other devices, from said communication line used for own communication and/or from said operating radio services are detected communication is at most or essentially performed on communication channels or communication spectra where said interferences from other devices or from radio services are not detected, thereby simultaneously avoiding interferences to and from other devices or radio services, wherein a pre-defined reference signal is generated by at least one device and transmitted via at least one available communication channel, wherein possible communication partner devices measure said pre-defined reference signal via channels other than said available, communication channels and/or analyze the respective measurement data, wherein based on said measurements said communication quality data, said communication spectrum data, said communication channel data, said communication spectrum and/or said communication channel are chosen or selected, thereby by fair avoidance avoiding and de-allocating at least one of communication spectra and communication channels associated with at least one of amateur, AM and DRM radio services or said other devices.
