In this paper we study the propagation characteristics of a typical central European forest. Radio propagation dynamics of forests should be better understood as performance of military applications, vehicular networks, and sensor deployments depend on radio performance. The measurement campaign we have conducted covered the frequencies of 750MHz and 2170MHz including two different transmitter locations...
We study the statistical characteristics of radio environment noise, in particular focusing on spurious received power arising from adjacent channel interference, harmonics and wideband man-made interference. Unlike the majority of existing studies, our measurements enable a comprehensive study on frequencies ranging from 80MHz to 2.64 GHz instead of being focused on the properties of an application-specific...
In this paper we report the preliminary results from the large-scale spectrum measurement campaign based study to find out correlations between spectrum use and socio-economical data. We use two large spectrum usage datasets that have been collected from metropolitan London and Paris, and correlate the spectrum usage of GSM, UMTS, and 2.4 GHz ISM band against the local population density and location...
In this paper we present results from a week long measurement campaign on spectrum use in London (UK). The measurements were conducted in order to understand the characteristics and especially the variability in spectrum use over different types of areas in a major metropolitan area. Three spectrum analyzers were used in the measurement campaign, one used for long-term measurements at a single location...
