Wireless connection using mm-waves and fibre

There is considerable interest and application potential in judiciously combining optical fibre and microwave/ mm-wave radio technology to effect efficient delivery of wireless telecommunication services. This paper explores the application of advanced optical fibre technology to the generation, and delivery to a remote antenna site, of mm-wave signals for future mobile radio and other wireless access services. The particular approach discussed deals also with the provision of a return link, utilising the same fibre as used for the forward link, from the antenna site to the base station to enable fun-duplex operation. The paper begins by outlining the need for such systems, stressing in particular the expected increase in demand for access to broadband services from a mobile or remote terminal. A description of the topology of a specific system demonstrator under development within the RACE programme is provided. This is followed by a discussion of some possible system applications, focusing in particular on the system's applicability to mobile telecommunications and the provision of telecommunication services to remote communities. The technology developed during this research project will allow the development of future standards for the definition of the interconnect between the fixed network and a mobile/remote user environment. The paper seeks also to expose broadband networks and services specialists to the capabilities of this emerging technology with a view to fostering its take up and exploitation. It is hoped that this may help to promote dialogue between the 'base technology' and the 'networks and system architectures' communities to ensure that the flexibility offered by this broadband deployment option is considered in future standards setting decisions.
