Abstract :
Efficient use of radio spectrum is a necessity for future wireless systems. This can, for example, be accomplished by cognitive radios. An important point for designing future systems is to gain knowledge about the occupation of the frequency bands which may be used by the cognitive radio. This includes the general characterization of the traffic density at the frequency bands as well as a detailed analysis of the temporal frequency occupation. Thus, this paper describes measurements taken in the GSM network at three different scenarios. Furthermore, a detailed analysis of the measurement results is presented including statistical as well as spectral occupation analysis.
