摘要
对WLAN(无线局域网)、GoTa、LTE和LTEGoTa等四种无线通信技术在城市轨道交通车地无线通信中的应用特点进行了分析比较,认为LTE-GoTa具有电信级可靠性、高带宽和强抗干扰能力,无线频点独占、运营级的技术,提供无线集群功能,以及下行40 Mbit/s,上行100Mbit/s等传输速率的无线宽带,可能是未来10年最佳的车地无线通信技术。
The communication system that providesrailway transmission for signal system demands anti-interference, stability, high bandwidth and high reliability, to ensure traf- fic safely and improve rail transport capacity. Four kinds of wireless communication technology, such as WLAN, GoTa, LTE and LTEGoTa Trunking System are compared, among them LTEGoTa can provide with carrierclass reliability, high bandwidth and strong anti-interference ability, its fre- quency point has deployed exclusively with telecom technol- ogy, providing wireless trunking with 40 Mbit/s downlink and 100 Mbit/s uplink wireless broadband, so it might be- come the best selection of wireless communication technol- ogy between train and wayside in the coming ten years.
