The Mobile Cloud supported by optical fiber

Abstract : In Europe, the competition between the mobile operators is so strong that the profitability of the mobile network has decreased. The cost to implement, to operate and to upgrade the mobile network is increasing while the revenues generated by the latter are not sufficient. Therefore, the operators should find the way to reduce the CAPEX and the OPEX. To keep competitive, the operators have begun to think about a novel RAN architecture. This new architecture is called Centralized or Cloud Radio Access Network. The traditional antenna site consists of the Radio Remote Head (RRH) which performs the radio processing, and the Base Band Unit (BBU) which carries out the digital processing. The principle of C-RAN consists to move the BBU from antenna site towards the local secured belonging to an operator called Central Office (CO). The move of BBU from antenna site to CO leads to the appearance of a new network segment called fronthaul. During this thesis, the different solutions to the deployment of fronthaul are studied and also the effects and the impacts of jitter on the fronthaul interface.
