Abstract

This paper introduces promising millimetre wave backhaul deployment options that serve an ultra-dense outdoor radio access network installed on street-level fixtures. A backhaul architecture which is based on either Cloud-RAN (C-RAN) or Distributed-RAN (D-RAN) configuration is introduced. We investigate the advantages and disadvantages of utilising millimetre wave in bands 71-76 and 81-86 GHz and free space optics (FSO) to fronthaul/backhaul links. As an initial study, the proposed architecture based on D-RAN is applied to a dense urban city area where moving vehicles and other users are served mixed traffic, including high resolution on demand and real time video. The analysis shows that the unevenly distributed traffic caused by different user types and mobility requires that the location and number of backhaul links need to be carefully designed to overcome the problems of bottlenecks on the backhaul links.
