Abstract:

The rapid developed high-speed railway is a new and challenging environment to provide mobile broadband data services as well as voice service, therefore it is important to investigate wireless broadband access techniques for this scenario. In this paper, a novel broadband wireless access network architecture based on radio over fiber is proposed according to the specific characteristics of high-speed railway. Then the corresponding media access control scheme and the mobility management approach are described.

Key words: high-speed railway, RoF, network architecture, fast handover
