| Abstract: | The train-ground wireless scheme would decide the running effect of metro PIS. With the development of domestic metro construction and technical improvement, the choice of PIS train-ground wireless scheme became the key content of metro communication system employee who should think about. The current domestic metro PIS train-ground wireless scheme was introduced emphatically. According to the current and future service demands, the status of application, the technical principle, the proper scheme that adapted PIS service demands was put forward finally. |
