Title:

Smart Spectrum Database for 5G and Beyond>

Abstract:

Future mobile communication systems beyond 5G are expected to be used by huge numbers of nodes in anywhere for anything. The serious problem for realization of the future wireless systems is scarcity of spectrum resource because almost all spectrums are already assigned to current systems. In particular, no extra spectrum exist below 6GHz, which is suitable for use for mobile communication. In this talk, a new concept of smart spectrum database which is a data and database driven spectrum management with dense spectrum sharing and for improving reliability is introduced. In this concept, the spectrum environment is measured by personal mobile terminals like smartphone as a crowd sensing and the measured data are gathered at the spectrum database. These data are used for spectrum modeling and spectrum management for improving the spectrum sharing performance and the reliability of communication. Examples of the structure of the spectrum database and results of field tests for confirming the concept are shown.
