Wavelength Interleaved DWDM Millimeter-Wave Radio over Fiber System: An efficient and consolidated approach towards deployment of hybrid last-mile optical and wireless communication systems

High-speed (mm-wave) radio-over-fiber (RoF) systems that have the potential to resolve the spectral congestion and the scarcity of bandwidth at microwave frequencies are considered promising technologies in distributing future broadband wireless access services. In these systems multiple antenna base stations (BSs) are directly interconnected to a central office via a fiber feeder network dedicated for performing all switching and signal processing functionality. The higher propagation losses of mm-wave signals however shrink the radio coverage and increase the number of BSs required covering a certain geographical area. Therefore it is imperative that the BS architecture be simplified and be cost-effective to realize, while the fiber feeder network must be capable of supporting the required large number of BSs. This book investigates the system technologies in implementing such simplified BS architectures and spectral efficiency in feeder network suitable for mm-wave RoF deployments. This also includes the integration of baseband, microwave, and mm-wave optical access technologies that simultaneously meet the demand for mobility, bandwidth, reliability, security and flexibility.
