Design framework for mm-wave frequency Radio-over-Fiber broadband wireless communication

Abstract

Radio over Fiber (RoF) systems have emerged as a cost effective solution for future multigigabit wireless networks operating at millimeter wave (mm-wave) bands. Such networks are composed of three subsystems: a central station, an optical distribution network, and several remote base stations. The design of an RoF land access network is a very knowledge-rich domain, due to the particularities and complexity of each network subsystem and their interrelation, as well as the fast evolution of the art. This paper presents a design framework to support engineers in the conceptual and preliminary design of a mm-wave frequency RoF broadband access network. The design methodology is validated in a case study of an in-vehicle RoF system for specific capacity and cost requirements.

Knowledge-based framework for the design of millimeter-wave (60 GHz) radio over fiber land networks

“…The outputs of the proposed system are found to be reasonable and very similar to those actually practiced manually by domain experts in industry for the example network design [112,113]. The proposed system is ready to be utilized for the design of 60 GHz RoF land networks.…”

“…Development of the proposed knowledge-based framework includes various steps such as knowledge acquisition, framing of design rules and attribute arrays, verification of design rules, sequencing of rules, identification of computer language, construction of knowledge base, choice of the design strategy, and preparation of user interface [112,113].…”
