The virtualized Radio Access Network (V-RAN) is a key technology for 5G networks. In this paper we present a live prototype of Virtual RAN implementing a Coordinated Scheduling algorithm enforced by a centralized coordinator. The 5G proof of concept, devised to improve the usage of radio resource and efficiency, is realized by exploiting open-source software to fully virtualize the LTE eNodeBs, and accommodates commercial terminals. We implemented two coordination algorithms: a simple static one for testing purposes, and a dynamic one appeared in [1]. Preliminary results show that coordination actually isolates the eNodeBs, reducing inter-cell interference.
