The most recent evolutionary steps in the development of mobile communication network architectures have introduced the concepts of virtualisation and slicing also into the Radio Access Network (RAN) part of the overall infrastructure. This trend has made RANs more flexible than ever before, facilitating resource sharing concepts which go far beyond the traditional infrastructure and RAN sharing schemes between commercial Mobile Network Operators (MNO). This paper introduces the EuWireless concept for a pan-European mobile network operator for research and presents its vision for RAN slicing and network resource sharing between the infrastructures of the EuWireless operator, commercial MNOs and local small-scale research testbeds around Europe. The EuWireless approach is to offer virtual large-scale testbeds, i.e. experiment slices, to European mobile network researchers by combining the experimental technologies from the local small-scale testbeds with the commercial MNO resources, such as licensed spectrum, through the distributed EuWireless architecture based on inter-connected local installations, so-called Points of Presences (PoP).
