Optical generation and delivery of modulated mm-waves for mobile communications
Future mobile communications is expected to make use of mm-wave frequencies, spectral congestion at lower frequencies making these effectively unavailable for broadband applications. The potential of optical fibre techniques to support the generation and remote delivery of mm-wave based mobile broadband services has been outlined, with particular reference to developments effected within the context of the EU RACE programme by project MODAL. It has been shown that such systems can be developed using optical and microwave/mm-wave technology which is readily available today. By employing optical techniques the flexibility for systems deployment is greatly increased, with optical fibre allowing signal transport over tens of kilometers, effecting benefits in base station interconnection and antenna siting and so contributing to low construction, installation and maintenance costs. The remainder of this introductory section will outline possible electrical methods for distributed mm wave generation and briefly outline some of the advantages that could be enjoyed if an optically-based method for the generation and distribution of mm-waves were to be adopted.
