Chinese Gao Tieke WiFi Internet access at the end of, 500 km/h did not affect Internet-high speed train-IT information

Chengdu electric high-speed train passengers through mobile APP, they can browse, send information to the Internet, and in addition can also watch over more than 30 WIFI free live TV--this is not a dream, but soon reality.

Often traveling passengers, poor network signal is very distressed. Research Institute of China electronic technology group Corporation 29th of satellite receiving equipment mounted on high-speed rail, has completed loading and waiting for further testing, is expected to be put into operation by the end of.

It is understood that the high-speed rail due to electromagnetic waves penetrate the body losses, Doppler frequency offset and frequent switching, base station, causing cell phone signals are often disconnected, data service results are even less so.

29 products foster introduced Wang Hailong, Deputy Director of the Centre, this technology comes from areas of military armor, Fang Cang-type satellite communications and other military vehicles. In early 2015, civil-military integration strategy background and strong support of Defense workers in Sichuan province, established wisdom 29 high-speed Internet industry incubation team, trying to use this technology in civilian areas.

After 1 years research and development, March 2016, the team delivered the first prototype for the display of the test, in July, the "China standard wisdom EMU high-speed Internet system" in long smooth finish loading, waiting for further tests.

"Currently China's Gao Tieyue of 350 kilometers per hour, this technology could meet within 500 kilometers per hour on the Internet are not affected in any way. "29 senior engineer Zhang Jie said that in addition, user-defined number of 700 people, currently the number of high-speed 8-carriage ride around 560 people, can accommodate all passengers at the same time access.

It is reported that the initial loading of 5 ha large, high-speed rail is the most extreme cold lines, tunnels and bridges on the big West, Zheng Xu line up to do further testing, is expected to start operation in December, and gradually expanding its coverage in China.

年底中国高铁可WiFi上网，时速500公里不影响上网 - 高铁 - IT资讯

新华社成都电 高铁乘客只需通过移动应用APP，便可以进行互联网浏览、信息发送，此外还可以通过WIFI畅通观看30多个电视直播节目——这不是梦想，而是指日可待的现实。

对于经常乘坐高铁的乘客来说，网络信号不佳一直令人十分苦恼。中国电子科技集团公司第二十九研究所研制的装载于高铁上的卫星收发设备，目前已完成装车并等待进一步测试，预计年底可投入运营。

据了解，高铁上由于电磁波穿透车体损耗大、多普勒频偏和基站频繁切换等原因，造成手机信号经常断线，数据业务效果则更不理想。

据二十九所产品培育中心副主任王海龙介绍，此项技术源于军用领域装甲型、方仓型等军用车辆上的卫星通讯。2015年初，在军民融合的战略背景和四川省国防工办的大力支持下，二十九所成立智慧高铁互联网产业孵化团队，努力将这一技术运用在民用领域。

经过1年多研发，2016年3月，研发团队交付了首套样机用于展示测试，7月，“中国标准动车组智慧高铁互联网系统”在长客顺利完成了装车，等待进一步的测试。

“目前中国最快的高铁约为350公里每小时，这一技术可满足在时速500公里内上网不受任何影响。”二十九所高级工程师张杰说，除此以外，用户设定人数为700人，目前高铁8节车厢可乘坐人数约为560人，完全能够容纳所有乘客同时接入。

据悉，初期装车的5辆高铁正在最极寒的哈大线、隧道和桥梁最多的大西线、郑徐线上做进一步测试，预计于12月投入运营，并逐步在中国扩大覆盖范围。
