To provide a broadband access for mobile communications, a new wireless infrastructure (Fibre Optic Networks for Distributed, Extendible Heterogeneous Radio Architectures and Service Provisioning – FUTON) based on Radio over Fibre (RoF) technology has been introduced. The FUTON intends to cover a geographical area that is divided into several serving areas, where multi-frequency remote access units (RAUs) are located. These RAUs are linked to a central unit (CU), using a transparent optical fiber system, and are able to send/receive signals from different wireless systems.
The FUTON fixed infrastructure provides flexibility to share its resources by a wide range of wireless systems and also by fixed optical connections. The supported systems should include, among others, outdoor Distributed Broadband Wireless Systems (DBWS), where the infrastructure acts as a virtual MIMO enabler to achieve the target high bit rates, indoor distributed broadband systems, and also the remote control of dedicated radio systems.
From the viewpoint of the DBWS or other legacy wireless systems to be integrated, the optical infrastructure is a transparent medium allowing the formation of a reliable network for a joint processing of the radio signals, although some specific physical layer algorithms (e.g. channel estimation), take into account the characteristics of the optical link. An interaction between the Common Radio Resource Management (CRRM) layer and an entity to manage the RoF infrastructure (RoF Manager) is necessary, so that the space (antenna) resources assigned to a specific wireless channel are mapped into the appropriate optical resources at the infrastructure.
This talk will give an overall FUTON Architecture and detailed radio resource management and network management with security in heterogeneous network scenarios using Wireless/Wired/RoF technologies will be discussed.
