Integration of EPON and WiMAX
The integration of EPON and WiMAX is a novel research topic that has received extensive interest from both industry and academia. The major motivations behind the integration of EPON and WiMAX involve the potential benefits of fixed mobile convergence (FMC), which uses a single network infrastructure to provide both wired and wireless access services, and a good match of capacity hierarchy between EPON and WiMAX by using EPON as a backhaul (or feeder) to connect multiple disperse WiMAX base stations. This chapter recaps recent progress in the area of integration of EPON and WiMAX. Three different integration architectures, including independent architectures, hybrid architectures, and microwave-over-fiber (MoF) architectures, are described. Based on these architectures, a range of planning and operational issues are discussed, including optimal passive optical network deployment to connect disperse WiMAX base stations, packet forwarding, bandwidth allocation and QoS support, handover operation for mobile users, survivability, and cooperative downstream transmission for broadcast services. We hope that this will interest readers and stimulate further investigation in the area.
