Spectrum occupancy measurement campaigns carried more than a decade ago revealed high licensed spectrum underutilization. Although a cognitive radio technology has been claimed to increase spectral efficiency by utilizing spectrum “white” spaces, its performance has been limited by imperfections of spectrum sensing and inter-device coordination. Currently, solutions utilizing Radio Environment Maps, being a specialized databases storing and processing information required for spectrum management, are gaining recognition and popularity.

This presentation will show overview of REM-based solutions proposed in standards and international projects. Next, an example of REM utilization for indoor-outdoor spectrum sharing will be shown. Finally, REM-based setup to protect a real network will be presented.
