| Abstract: | This paper introduced the CBTC Data Communication Network. According to the redundancy of backbone network, it was established two AP databases, which corresponded to two set of on-board radio. The on-board radio management module was designed in on-board equipment to exclude the illegal radio interferences by the AP databases, implemented the handoff between wireless coverage areas, ensure the handoff safety and stability. |
