Facing the challenge of providing broadband access to high speed vehicle on motorway scenario, this paper1discloses a fibre network employing star-tree architecture with a central control system in the middle to connect fixed line data collection part on one side and the wireless points to transmit information needed to on road vehicles on the other side. To implement the system, an effective coverage scheme is presented by using radio-over-fibre (RoF) technologies, in which time slot distributor (TSD) plays a key role in avoiding co-channel interference. With adaptive modulation approaches under different channel condition, a buffer management scheme (BMS) could achieve a better system performance. Furthermore, within new frame structure, four handover indicators are added to deal with the fast handovers involved among remote antenna units (RAUs) governed by single base station (BS) and handover between different BSs.
