随着我国铁路和城市轨道交通的迅速发展,用于铁路及地铁系统的专用业务移动通信也得到长足的进步,特别是进入20世纪90年代以来,中国从国外引进的集群无线通信系统正在逐步替代原有单信道有线/无线转接系统。近年来,一种先进的集群通信技术(TE-TRA)又将替代模拟集群通信技术,在铁路和城市轨道交通系统中崭露头角,备受各方面的关注。
With the rapid development of railways and urban rail transit in our country, the mobile communication dedicated to the railway and subway systems has also made great strides. Especially since the 1990s, the cluster wireless communication system introduced by China from China is gradually replacing The original single-channel cable / wireless transfer system. In recent years, an advanced trunking communications technology (TE-TRA) will replace the analog trunking communications technology, emerge in the railway and urban rail transit system, has attracted all attention.
