In this article the author presents the RoF technology based broadband access network architecture for the metro and
intercity trains, analyzes the relating issues in realizing the network, and addresses challenges towards the direction.
The author first identifies insufficiency of the present wireless communication infrastructure, reviews the RoF
technology and its characteristics, presents the network architecture meeting the performance and reliability, describes
multi-diversities mechanisms for the two-channel transmission, discusses the RoF system structures and their
realization, and finally analyzes the issues of the MMW propagation.
The network planner of the incumbent telecom service provider faces a series of challenges following technology developments, riding demand changes and utilizing existing resources. It is believed that the telecom planning that was started from the early time for PSTN deployment has been contributed to the foundation for the telecom planning but does not provide enough methodologies to help today's planning activities. The planning work for the provider must make innovation for adapting to the dynamic environment and supporting business development. In this paper, the situations and trends faced by the telecom service provider are first reviewed, the planning system restructure and planning methodologies innovation for meeting present situations are then presented, and the issues and directions are finally summarized.
Advanced network planning concerns effective network-resource allocation for dynamic and open business environment. Planning methodologies of ASON implementation based on qualitative analysis and mathematical modeling are presented in this paper. The methodology includes method of rationalizing technology and architecture, building network and nodal models, and developing dynamic programming for multi-period deployment. The multi-layered nodal architecture proposed here can accommodate various nodal configurations for a multi-plane optical network and the network modeling presented here computes the required network elements for optimizing resource allocation.
This paper concerns about optical switching transport network planning methodologies and the associated economic perspective analysis. Mathematical expressions for algorithms to determine network elements in various scenarios such the segmented networks as well as the hybrid-granularity demands are developed for modeling network architectures.
