| Abstract: | According to the characteristics of high-speed railway coverage,it gives the suggestions that the WCDMA coverage for high-speed railway should be planned to realize seamless coverage of AMR 12.2 kbit/s service at the base of the existed network.It gives the reference distance between adjacent base stations according to the analysis of link budget and the test results of several high-speed railways.Finally it introduces the techniques to reduce the handover frequency and improve the quality of high-speed railway coverage. |
