Network Planning for Next-Generation Metropolitan-Area Broadband Access Under EPON-WiMAX Integration

Free registration required

Executive Summary

This paper tackles a fundamental problem of network planning and dimensioning under EPON-WiMAX integration for next-generation wireless metropolitan-area broadband access. Due to the powerful coordination capability of the Optical Line Terminal (OLT), inter-cell collaboration through physical layer Cooperative Transmission (CT) among the Optical Network Unit-Base Stations (ONU-BSs) can be initiated. In order to achieve the most efficient deployment of network infrastructure and meet the long-term performance requirements, the proposed planning and dimensioning model jointly considers the problems of ONU-BS placement, BS-User (BU) association, and Resource Breakdown Assignment (RBA), which are further formulated into a combinatorial optimization problem.
