Abstract :
Integrating optical and wireless broadband access networks is an important step in achieving fixed mobile convergence in metropolitan areas. In this paper, a promising network architecture by integrating a passive optical network and a wireless cooperative network is investigated, in which intercell cooperative transmission is incorporated. Our goal is to exploit both economic and performance benefits. To achieve a cost-effective deployment and meet long-term performance requirements, this paper addresses the issue of dimensioning and site planning (DSP). We provide a complete formulation to capture the challenges behind network deployment. A number of long-term design subjects are jointly considered in a unified optimization framework, including infrastructure placement, base station user allocation, and resource breakdown assignment. To reduce the computation complexity, the DSP problem is decomposed into two subproblems. An approach is further developed to reformulate the problem into a solvable mixed integer linear program. Moreover, we conduct case studies to validate the formulation, in which performance gains are demonstrated in terms of total infrastructure cost reduction, spectral efficiency improvement, and scalability in capacity enhancement.
