In its Communication on "Promoting the shared use of radio spectrum resources in the internal market" the Commission pushes and supports Member States to move to an enhanced innovation-friendly internal market framework for the shared use of spectrum. Meeting the growing spectrum needs resulting from the exponential growth in wireless data traffic and the increasing importance of wireless connectivity in the economy, is limited by the absence of vacant spectrum. However, the radio spectrum is a unique resource that can be re-used more efficiently with advances in technologies. This makes additional spectrum resources available and lowers the spectrum access hurdles for new users. To cope with the demand and to attract investments into new technologies, the EU needs a supportive regulatory framework that enables legally binding spectrum sharing contracts between users to encourage wireless innovation in the internal market.
