Cloud radio access network: Virtualizing wireless access for dense heterogeneous systems [PDF]
Journal of Communications and Networks, 2016 Cloud Radio Access Network (C-RAN) refers to the virtualization of base station functionalities by means of cloud computing. This results in a novel cellular architecture in which low-cost wireless access points, known as radio units (RUs) or remote radio heads (RRHs), are centrally managed by a reconfigurable centralized "cloud", or central, unit (CU).
