Ethernet fibre transport in cloud-radio access networks

Cloud-radio access networks with digitised radio signal transport between a pool of baseband units and distributed, remote radio heads promise a number of advantages in network deployment, from performance improvements to cost and energy savings. Current digitised links are based on industry standards such as CPRI (Common Public Radio Interface) but these need redefinition as the required bit-rates increase. The transport mechanisms are also different to those used in data networks. This work examines the advantages and challenges of using Ethernet fibre links instead of the CPRI-type technologies. The work is supported by a UK EPSRC grant “NIRVANA” which is coordinated by Nathan Gomes and involves collaboration with University of Essex and industry partners at JDSU UK, EE, BT, NEC, Qualcomm, and Techgate (
