With the increase of the transmission bit rate on optical fibers, it is now possible to transmit a radio base band signal over long distances. A very promising technology called Digital Radio Over Fiber (DRoF) uses this principle and allows centralization of resource management in the base station architecture. This architecture consists of three components: a Base Band Unit (BBU), a Remote Radio Head (RRH) and the interface between them such as CPRI (Common Public Radio Interface). In this paper, we propose to use the DRoF technology to virtualize current residential gateways making them less complex and allowing centralization of resource management. We show that the propagation delay can be a serious issue with Wi-Fi as we increase the distance between terminals and the access point.
