The researchers have conducted a strict and complete spectrum measurement from December 2006 to July 2007 at two locations in Aachen, Germany, and one location in Maastricht, Netherlands. The measured bands ranges from 20MHz to 6GHz and are composed of four subbands of each1.5GHz bandwidth. A resolution bandwidth of 200 kHz is chosen as a compromise between frequency resolution and the maximum supported span. So, each subband of 1.5GHz bandwidth includes 8192 measurement points, which will cause a small overlap between adjacent measurement channels. The inter-sample time is about 1.8s that means there will be about1000 measured PSD values obtained in 30 minutes for each measurement point by the measurement system. In this paper, almost all the bands carrying the popular services will be included in our analysis. However, due to a lack of public permission, only a small amount of the data is provided here for reference.
