Radio over fiber based signal transport schemes for emerging mobile fronthaul networks – a review

Abstract

Abstract Radio over fiber plays a prominent role in the realization of next generation integrated Optical -Wireless Networks to distribute mobile broadband signals effectively to meet the increasing demand of multimedia services with guaranteed quality of services. In this paper the signal transport schemes of analog and digitized Radio over fiber systems with relevance to cellular communication and the comparison of different Radio over fiber systems with their merits and demerits is explored. Further, review of existing different types of multioperator multiservice architectures to realize high performance Radio over fiber based fronthaul architectures also presented in detail.
