In this paper, the authors present the concepts of network virtualization, focusing specifically on wireless virtualization of the LTE mobile communication system. A novel wireless virtualization framework is proposed and developed, which allows mobile network operators to share the wireless spectrum, as well as, the infrastructure (i.e., hardwares equipment). The framework targets the concepts of wireless virtualization applied within the 3GPP Long Term Evolution (LTE) system. LTE represents one of the new mobile communication systems that are just entering the market.
