Abstract
WiMAX is a standards-based wireless technology that provides high-throughput broadband connections over long distance. However, deploying conventional size of WiMAX BS on the motorway will lead to low effective coverage and wireless resource waste, in which a large proportion of wireless coverage areas may not have any traffic flow at all. This paper develops the optimized cell size first based on the certain width of motorway and the overlapping length between adjacent motor-picocells, and then supposes a system design and implementation through the combination of TDMA and RoF technologies. By coverting conventional cells into motor-picocells of RAUs, the effective coverage can be improved greatly. Furthermore, four handover indicators are introduced to deal with the frequent handovers evolved among RAUs governed by single BS and handover between different BSs. A novel concept of TSD is introduced here to avoid co-channel interferences and make the system cost-effective.
