Proof-of-Concept of Capacity Expansion Through Extended Dynamic Spectrum Access for 5G

Mobile communication networks are typically based on a fixed spectrum assignment policy. However, a portion of the assigned spectrum is used only sporadically and with some geographical variations. The scarcity of spectrum and its inefficient utilization impede meeting the growing user demand for higher capacity and availability. To help solving such issue, the 5G PPP project SPEED-5G has defined a concept that allows dynamic allocation of spectrum, thus optimising the usage of scarce spectral resources. While the project has defined concepts and components in its first phase, several experiments have been designed and made and first results are now available. The objective of this paper is to describe the demonstrator setup and selected Proof-of-Concepts, their mechanisms and the results achieved.
