Spectrum Measurements supporting Reconfiguration in Heterogeneous Networks

This paper represents spectrum occupation measurements performed during the Soccer World Cup 2006 in Germany. The measurements cover the range from 400 MHz up to 2600 MHz including among other communication standards GSM 900, DCS 1800, UMTS, and WiFi. The intention of the paper is to compare spectrum occupation during a mega-event to spectrum allocation in a "normal usage" situation and to investigate correlation between the received power levels and specific events, e.g., scoring within a match. These results form the basis for a metric that may be assigned for dynamic spectrum access in heterogeneous radio environments. Measurement results are deeply investigated with respect to time-dependent and peak power statistics as well as quality of service considerations. Quality of service in that case is represented in terms of succeeded voice calls, data calls and data transfers as well as average throughput.
